A set of 4 coasters with a blue bubble butterfly design. Each coaster is 10cm x 10cm.
These coasters have been made by sifting a mix of copper oxide powder and clear powder frit onto a layer of clear glass with a stencil. A second layer of clear glass was placed on top. During firing the copper oxide turns a brilliant blue and bubbles are created with the two layers of glass.
Each coaster is fitted with rubber feet to protect surfaces.
We do not use single use plastic in the production
