1. Soften your clay with your hand, until you get it to the consistency that it can be pressed into the mould.
2. Press the soften clay into the mould, gently bend mould to release the pressed shape. If you find that the clay is sticking to the mould you can use a releasing agent like talcum powder or spray a fine mist of water onto the mould.
3. Add mica powder (Pearl Ex) to the pressed shapes to make them come alive. Dip a brush into the Pearl Ex container, brush off excess powder and then gently brush over pressed shape.
4. Bake the finished pieces
Bake your clay pieces on an oven-proof glass or metal surface at the baking temperature and time listed on the package. DO NOT USE MICROWAVE OVEN. DO NOT exceed the recommended baking temperature or baking time. Carefully remove from oven and allow to cool. Baking should be completed by an adult.
275 °F (130 °C)
30 minutes per 1/4 inch (6 mm) thickness
While many items used with polymer clay may be found in our home kitchens, once used for polymer clay, they should not be used for food purposes.
5. If you have any polymer clay on the edges of the letters or number you can remove this once it is baked with a sharp craft knife. This may not be necessary if you are grouting, as you only see what is on top.
6. Sealing the tile / embellishment
You can seal your tiles with Sculpey Glaze Gloss or Satin which provide a smooth seal to set your clay, cover imperfections, increase durability.
If you decide to grout your mosaic, make sure you cover your letters or numbers with blue tack first to prevent the tiles absorbing the colour from the grout.
As polymer clay is waterproof your tiles can be used inside and out, do not place in direct sunlight as there colour may fade.
