Art in Oceania

The visual art and architecture of native Oceania, includes media such as sculpture, pottery, rock art, masks and personal decoration. In these societies, art and architecture have often been closely connected, for example, storehouses and meetinghouses have been decorated with beautiful carvings, and so they are presented together here.

Until the 16th and 17th centuries when European societies arrived upon the scene, Oceanic societies maintained various forms of Neolithic technology. The only exception was in the northwest of New Guinea, where the people living around Geelvink Bay (Teluk Cenderawasih) imported very small quantities of metal from the Indonesians of the Moluccas (Maluku). The art of forging was carefully guarded, like a cult secret; some tools were traded but only in amounts too small to have made much impact on normal working conditions.

Throughout the rest of Melanesia and in Polynesia and Micronesia, the basic tool remained the stone blade, which was hewed as an adze or an axe, and at times interchangeably as both. Tridacna shell was occasionally used for blades in those parts of Oceania where stone was in short supply, including Micronesia and the Solomon Islands. When obsidian became available, it was chipped into blades for use as both weapons and tools. Other suitable materials included bamboo and bivalve shells, which take very sharp edges. Some fine cutting and engraving was done with unhafted boar tusks or with hafted shark and rodent teeth. Animal bones served as gouges, awls, and needles. All these instruments were used in working wood, which with very rare exceptions was the main medium used throughout Oceania.

Clay was also used, mainly for sculptures, for some small musical instruments (whistles), and for pottery in Melanesia and New Guinea. The making of pottery vessels was almost exclusively women’s work, except in only a few areas in New Guinea and the northern Solomons. A typical method involved spiral coiling of rolls of clay. The decorating of the pot was the work of men.

Some working of shell and turtle shell was done with simple drilling and abrading equipment. The carving of stone, although obviously presenting far more arduous and time-consuming problems than wood, was employed remarkably often and occurred throughout the Pacific Islands; hammering, pecking, and polishing were the main methods. Even so resistant a material as greenstone was mastered by grinding with abrasives.

Paint and painting were thought to animate sculpture, sometimes literally, in religiosymbolic terms, as paint was considered to have magical, vivifying powers. Paints were usually ochres, with some vegetable-derived pigments. Water was the typical medium, on occasion supplemented with sap. Brushes were created from the fibrous ends of chewed or frayed sticks, small feather bundles, pieces of wood, and sometimes the most elementary applicator of all, the finger. Apart from sculpture, the surfaces used for painting were rock faces, bark, and tapa (cloth made from worked bark). Rock painting was most common in Australia, where panels of bark were also used. In Melanesia, paintings were made mainly on sago-palm spathes and sheets of tapa cloth. In Polynesia the women manufactured great quantities of tapa, which were then decorated with traditional designs using vegetable dyes. Some of the techniques they employed included painting, stenciling with leaf templates, rubbing over relief-design tables, stamping, and printing with carved bamboo rollers.

The only areas where weaving was practiced were the Caroline Islands, the Polynesian outliers east of the Solomon Islands, a small number of the Santa Cruz Islands, parts of Vanuatu, the Saint Matthias Group (northwest of New Ireland), and a few places on the northern coast of Irian Jaya. Spinning was unknown; instead of yarn or thread, strips of banana fibre were used on a simple backstrap loom. Weaving was a woman’s craft in the Caroline and Saint Matthias islands but was practiced by men elsewhere. A form of “finger weaving,” as in net making, was used by Maori women in creating textiles from flax fibres.

The architecture of the Pacific Islands was varied and sometimes large in scale. Buildings reflected the structure and preoccupations of the cultures that constructed them, with considerable symbolic detail. Technically, most buildings in Oceania were no more than simple assemblages of poles held together with cane lashings; only in the Caroline Islands were complex methods of joining and pegging known.

Oceanic artists’ quest for media was completely opportunistic; they regarded almost anything from the lavish natural world that surrounded them as potentially usable. The ocean yielded shells of all kinds, especially conus, cowrie, and nassa shells. Birds gave down, beaks, and plumes (those of the birds of paradise were especially prized); animals provided teeth, tusks, and skins; insects supplied wonderfully brilliant wing cases. The vegetable kingdom was drawn upon for flowers, leaves, and fibres. The assembly of such materials into single objects was rare in Polynesia and Micronesia, but the practice was typical of Australian and Melanesian styles, and added brilliantly to their more spectacular effects. The most basic medium of all was the human body, which allowed for both removable and permanent decorations, including scarification, enhanced by treatment to raise keloid welts in New Guinea, and tattooing with needles and pigments elsewhere.

How to get the most from your Grid-Connected Solar Power System

Ok, so you’ve just had your brand new grid-connected solar panels connected by your friendly accredited solar power installer.

Now, think back to the initial meeting you had with the sales consultant around the kitchen table. Do you recall discussing your previous energy use in the home, and what habits you ought to change if you decided to get solar? If you answered yes, then you probably organised your solar quote through mysolarprice.com.au, as we only deal with solar companies that we are certain will educate the consumer about their typical power use and give them a great understanding of what power output the system is capable of. Some ‘fly-by-night’ solar panel companies who have only recently arrived on the scene have misled the public in the performance capacity of their grid connected systems. This has led to some mistrust and confusion in the Solar arena. Mysolarprice.com.au knows of these companies, and will not deal with the solar installers found to be giving misleading information or involved in any dishonest sales tactics.

Have you forgotten the power saving tips the solar consultant gave you? If so, don’t worry, as we have the TOP 15 tips for reducing your power consumption to get the most out of your tariff feed, whether that be Net Tariff feed or Gross Tariff feed. Some businesses with larger systems from 2kw (2 kilowatts) or more may not have to modify their electricity usage at all and will still be in positive territory, that is, able to get a surplus or credit for their power. This depends on the home, roof type, shade, number of people in the home, appliance usage, and most importantly their behaviour in the home or in other words how they interact with their home. Some families work during the day and turn their standby power off, whilst doing their washing and household chores at night time. Whereas some people have an air-conditioned home office which uses a massive amount of power during the day and which does little at night. How does this make a difference you may ask? If you are in a state like Queensland which has a “Net Tariff Feed” this is extremely important. A Net tariff feed basically means you get the balance of the power you send to the grid from the amount of power youhave used during the day but not at night, because solar panels don’d generate power at night time. Therefore, if you are using a lot of power during daytime when your solar power system is working the hardest, you are competing or cancelling it out with the amount of power you are feeding back to the grid, or “Net” Feed. If however, you are out during the day and turn off all your appliances at the wall to eliminate inactive and active standby but only leave the essential items on like the fridge, you will be streets ahead of the rest and get more of a “net” balance which means one thing: more $$$$$$ in your pocket!

These top 15 energy saving tips range from modifying the building fabric of the home, to being more energy efficient, to minor behavioural modifications like turning off the lights when you leave the room. This list is in the order of the simplest minor behaviour modifications to bigger structural changes to the building material.

TOP 15 POWER-REDUCING TIPS

1.Turn the lights off when you vacate a room. This is very important if you have energy-guzzling old-fashioned incandescent lights or worse, halogen lights. I have seen people leave on 4 x tastic 500w heat lamps on in the bathroom all day. That’s an incredible 2KW or 2000 watts of power being consumed for no reason.

2.Allow natural light into the rooms. This will reduce the requirements for lights during the day.

3.Replace your incandescent light bulbs and halogens with CFL’s (Compact Fluorescent Lamps) or LED’s. They use only around a quarter or less power than the standard 75watt incandescent or 60watt halogen, and can last far longer than the standard incandescents or halogens.

4.Use Sensor CFL spotlights outside, instead of the old energy-inefficient spotlights of yesteryear.

5.Turn off all standby power. This is probably the best tip I can give you for reducing your daily electricity consumption. A typical dwelling generally operates at around 10-15% standby power, so if you have a quarterly bill of $400 that means $40-$60 of that bill is standby power -which does nothing! It may not sound like much but that’s around $120-$240 a year just for not turning appliances off at the wall. An easy way to monitor your standby is to install a proper standby power board.

6.Choose energy-efficient appliances. This doesn’t necessarily mean throwing out your 5-year-old fridge because it only has 2 stars, and spending $2,500 on one that is 4 star. It means if you are presented with an option of buying a new appliance, then make sure it has the highest star rating available. So if you have the money and the choice is over a 2 star 50 inch plasma TV or a 5 star 50 inch Led TV you should get the LED.

7.Turn off any second or third fridges not in use. I have found in energy audits that many people have a spare chest freezer or 20-year-old rusting fridge with deteriorated seals in a hot garage. This will account for a large chunk of your electricity bill. Sometimes I’ve opened the door and there is nothing even in there, so the fridge is running -and working overtime- for no reason.

8.Turn off your computer monitors and speakers when not in use. This is so easy, but most people I come across forget to do this. If you have a Sub-Woofer with a separate power supply be sure to turn that off also when not in use.

9.Draft Sealing in Winter. If you are using electric heating in winter, be sure to stop any drafts, otherwise you are simply wasting money.

10.Use ceiling fans or pedestal fans instead of air-conditioning. Air-conditioning can be one of the most expensive appliances to run in summer. If are going to use air-conditioning in summer, make sure that the room is properly sealed, the windows are covered and you have insulation in the ceiling.

11.Air-Conditioning Tips for Summer.

- Buy the optimum sized air-conditioner for your room -not house, unless it’s ducted. If buying ducted make sure it can be zoned.
- Buy an energy efficient inverter air-conditioner with a high star rating for both cooling and heating.
- Set the thermostat between 18-21 degrees. Every degree celsius higher that you set the a/c increases its consumption by 10%
- Re-circulate cool air from the inside instead of using hot air from outside. If the compressor is outside be sure its not sitting exposed in the western sun.
- Ensure the windows have both internal and external shading.

12.Air-Conditioning Tips for Winter.

- Set the thermostat to 23-26 degrees
- Wear warmer clothes to insulate your body so you need less mechanical heating
- Insulate your space as with Air-Conditioning in Summer Tips.
- Because hot air rises, a ceiling fan can be turned to the lowest setting -in reverse- as this actually pushes the warm air down towards the home’s occupants
- Avoid electric radiator heaters and electric fan heaters as they are massively expensive.
It is better using reverse cycle air conditioning as it’s a great deal cheaper (most people don’t know this).

13.Insulation. Reflective foil type insulation is better in sub-tropical climates such as Brisbane receives, but thicker, bulky insulation such as wool/fibreglass or polyester is best suited to the more temperate climates such as Toowoomba.

14.Windows. There are a number of things you can do to insulate your windows to stop the heat entering the dwelling during summer, and keep it in during winter. In summer it’s important to keep direct sun rays off the east and west windows by vertical screening, and keep it off north facing windows with big eaves or horizontal shading. This is so you can let the sun in during winter when it is lower in the sky. These are principles known as solar passive design.

15.Hot Water. If your house has an electric hot water system and it is on the wrong tariff this can be the greater part of your bill. Generally, your hot water should be on an off-peak tariff depending on your location and retail provider. Your hot water bill is normally a quarter of a electricity bill if the system is electric. If it is a relatively new heat pump it will be much less. The most efficient water heating device is Solar Hot Water, with a natural gas boost.

These are just a few of the basic energy-saving tips I have come across when performing household energy audits which I find many people need help with. If you can reduce the daily consumption it’s going to make it a lot easier to:
1. Keep your bills down, and
2. Make it easier for the Solar Panels to work and provide you with a bonus or credit on your next bill.

One other thing I forgot to mention is panel care. Your panels should be kept free of dirt and grime, as even a small build-up of dust on the panels can significantly reduce the panel’s performance by up to 30% or more. I will look at the process of solar panel maintenance in my next article.

Why you should turn to stone cladding when building your dream home

If you talk to anyone who’s knowledgeable about stone cladding, they’re most likely to tell you one thing over anything else: it’s the bee’s knees. Really, a stack of rocks and stone never looked so good. If you’re planning at building your own dream home, you might want to consider including stone cladding in the final design of your house.

Far from looking like your typical bunch of rocks stacked on top of each other, the majority of constructions that use stone cladding can look very aesthetically pleasing, not to mention reliable and very easy to build. Stacked stone examples exist far and wide and can be found in a multitude of places. Take for example a certain country retreat in the Daylesford Hills in Victoria, where they opted to use stacked stone instead of the usual sandstone walling. The architect ended up choosing Craft Stone European Castle Stone Golden Sand as the alternative.

What resulted from this was a far more pleasant design and they avoided additional footings, particularly by using timber frame & fibre cement as a substrate. This was used in an outdoor portion – a rock wall if you will – so it’s something that will easily catch the attention of passersby if they ever come across it.

But of course, usage is in no way limited for outdoor portions of a house. Indoor use is also popular, and when it comes to cases like these, its benefits can be experienced in a number of ways of ways, whether it ends up in the kitchen or in the bedroom.

A stacked stone fireplace can take advantage of such an architectural marvel, where a timber frame clad with fibre cement sheet can be used to construct a stone gas log fireplace. A 12mm Standard mortar joint can be used to fit the Craft Stone Stacked Ledgestone Merlot for the construction. The best part is the whole thing takes a day to construct which brings to light the astounding cost and labor saving incentives . It’s obvious – less construction time means less labour costs, and fewer expenses in general.

With clear benefits such as those mentioned above, it’s no wonder the stone cladding method is becoming more and more popular nowadays. Add the fact that resulting designs can compliment just about any design, and suddenly it’s not so hard to see why people say it’s the perfect design feature. Stone cladding is what dream homes are made of!

The Importance of Decorative Night Lights in Interior Design

Lighting is an important aspect of any room. It takes a lot of effort and consideration to choose the right night lights, as it can make or break a room. Decorative lights can easily liven up a space, irrespective of how average the furniture is. Lighting plays an essential in creating the ambience in a room. Where you place these lights should also be planned well, as wrong placement can ruin the mood in a room.

Interior design has significantly evolved throughout the years, as decorative pieces and furniture have come to represent a more contemporary look to them. With the development of interior design trends came the similar evolution of lighting. Designer night lights have become one of the most important aspects of a interior design project. Choosing decorative lights that make a statement fulfills both the aesthetic and as well as the functional side of the designing process. Whether you want classic designs or modern ones, there is definitely a lighting piece that will suit your needs and preferences.

Adding a lampshade or two in a bedroom can make a huge difference. Drop lights are also welcome additions to the living room and the dining room and string lights are increasingly becoming a necessity when decorating. There are so many different choices for night lights today that it can be rather overwhelming to choose. Decorative lights provide an interesting feel to the room and depending on the kind of light you decide to use, it can create the overall theme of the room. More contemporary designs include LED colour change lights, large drop lights and metallic lighting fixtures. irregardless of what your interior design theme is, you can find a lighting fixture that will be ideal. This even extends to the gardens and water features with outdoor lighting.

A lot of the modern lights today are also more cost-efficient they don’t consume too much electricity as they used to. It is preffered to decide on one center light and include several accent lights so that you are able to dim the lighting in the room should you want to. Warm lighting can greatly influence the ambience in the room, as it is a lot more comfortable than white lights.

Chandeliers have also greatly evolved through the decades. From elaborate tear drop chandeliers, they now come in varying colours and designs. Dark wrought iron chandeliers offer more simplistic options for homes, as they are not as ornamental as traditional chandeliers but can be as beautiful in design and lighting. Decorative night lights are certainly a wonderful investment, as they can improve the aesthetic appeal of any home.

Plastic Packaging Facts

Because packaging helps to control the present environment of a food product, it is useful in creating conditions that lengthen the storage life of a food. Packaging materials that are usually used for foods may be classified as flexible (paper, thin laminates, and plastic film), semi-rigid (aluminum foil, laminates, paperboard, and thermoformed plastic), and rigid (metal, glass, and thick plastic). Plastic materials are widely used in food packaging because they are relatively cheap, lightweight, and easy to form into desired shapes.

The selective permeability of polymer-based materials to gases, such as carbon dioxide and oxygen, as well as light and moisture, has led to the invention of modified-atmosphere packaging. If the barrier materials are carefully selected, a packaging material can continue a modified atmosphere inside the package and thus extend the shelf life of the food product.

Dehydrated foods must be kept apart from moisture during storage. Packaging materials such as polyvinyl chloride, polyvinylidene chloride, and polypropylene have low moisture permeability. Similarly, packaging materials with low gas permeability are used for fatty foods in order to minimize oxidation reactions. Because fresh fruits and vegetables respire, they use packaging materials, such as polyethylene, that have high permeability to gases.

Smart packages offer properties that meet the unique needs of certain foods. For example, packages produced with oxygen-absorbing chemicals remove oxygen from the inside of the package, thus guarding oxygen-sensitive products from oxidation. Temperature-sensitive films exhibit an abrupt change in gas permeability when they are submitted to a temperature above or below a set constant. These films change from a crystalline structure to an amorphous structure at a set temperature, causing the gas permeability to change substantially.

If you are looking for shrink packaging film and shrink wrap equipment, talk to Redblade. Redblade are the experts in plastic packaging and Cryrovac film.
