This coaster is a mixture of two of my favourite techniques – printing and kiln formed glass.
First, the coloured background is created using a variety of glass powders over a warm white glass. Each colour is hand sifted, each one is unique and I cannot accurately predict the outcome or distribution and depth of colour. Another layer of glass, clear this time, is added on top to create depth, and to give the coasters a substantial feel. The two layers are then fired to a full fuse to become one single smooth piece. They go into in one of the studio specialist digitally controlled, dedicated glass fusing kilns, and area annealed for strength and durability (a controlled cooling process to ensure there is no stress in the glass) – each firing cycle takes between 18 and 24 hours. Once fully fused, the top layer is screen printed with glass enamels – again, although a stencil is used, the image is hand placed and squeegied, so each print will be slightly different. It goes back into the kiln to fuse the enamel to the glass to make the image permanent.
The coaster is 10cm square, and it has four rubber bump-ons in the reverse side to protect your surfaces.
We do not recommend you put your coasters in the dishwasher. Whilst the glass is fully washable, it’s best just to only wipe the surface, or if you spill your cuppa on it, you can wash it in warm soapy water.
