Art Clay Silver Paste is a composite material, made of fine silver powder and water-soluble or oil-soluble organic binders. It looks and feels like dull-grey double cream. During firing, the binders vaporise, the powder sinters, and the soft clay turns into real solid 999 silver: ready to wear, give, or sell.
Art Clay Silver Clay fires at 650°C held for 30 minutes or 800°C held for 5 minutes. The fired metal is solid silver, which can be hallmarked as pure 999 silver. A wide range of other materials can be combined with it before firing.
The water-based silver paste has three main uses: to paint onto a mould; to add shape to existing unfired silver clay; or to stick two pieces of unfired silver clay together. It's often used on a cork-clay shape, a leaf, or an organic texture so that, after firing, a delicate shape remains.
The oil-based paste has three main uses: to add shape to existing fired silver clay; to stick two pieces of fired silver clay together; or to repair a broken fired silver piece.
The overlay paste has one main use: to add silver highlights, texture, or decoration to fired silver clay, glazed ceramics, glass, or porcelain.
Although you can fire Art Clay 650 on a kitchen gas hob, on a camping gaz ring, or with a butane torch, it's more reliable to use a kiln. To learn more about kilns, transfer to Electric Kilns using the link above the menu bar near the top of the page.
|USING THE PASTE|
The paste comes in a small plastic screw-top bottle. Take as much as you need, using a modelling tool or a soft wet brush, and replace the lid. As you apply the clay, you can use a little water to smooth the surface and optimise the adhesion.
Whilst working, don't let any clay dry on your tools: keep your brush tips in water and dab them on lint-free cloth just before use. Save scraps of clay in a small airtight container.
Dry silver clay for 24 hours in a warm place, or in a kiln programmed from cool to 150°C then held for 10 minutes: although, with care, you can dry it with a hair drier or a hot air gun, on a central heating radiator, or in a kitchen oven.
After drying, silver clay looks and feels like dull-white plaster. It's strong enough for you to be able to refine the shape using a knife, a scriber, a file, a drill, and abrasives. However, at this stage, thin pieces are brittle, so may snap.
Fire silver clay in a kiln programmed from cool to 650°C, then held for 30 minutes: although, with care, you can fire small pieces on a kitchen gas hob, on a camping gaz ring, or with a butane torch. If your piece doesn't include anything that will crack or melt at a higher temperature, it can be fired at 800°C for 5 minutes.
As it's heated, the organic binders vaporise and small amounts of non-toxic carbon dioxide and water vapour are released: so it's safe to use at home.
After firing, the clay still looks dull, but brushing off the powdery coating reveals bright metal. Your piece is now ready to reshape, drill, stain, polish, tumble, or burnish. Remember, it is metal: it doesn't just look like metal.
|ART CLAY UK|
is a Cherry Heaven internet resource. Cherry Heaven is a top-tier international distributor for Texas-made Paragon kilns, furnaces, and ovens, and has been one of their top-selling partners from 2006 to : a pleasing outcome since the UK is only one third the area of Texas and one fortieth the area of the US.
Although Paragon kilns are very reliable, we normally have relays, thermocouples, heating muffles, programmers, and shelf kits in stock: even small parts such as screws, door hinges, bits of wire, and element connectors. Elements are the exception as there are so many variants, but these arrive air-xpress regularly.
As this is an on-line resource, there isn't a paper catalogue or a price list. However, you can mail or call about kilns, power supplies, public area safety, a special project, business ideas, diagnostics, repairs, or reselling opportunities.
