This flat round mould has a smooth interior and is used to make a coaster. Use our heat-resistant resin to make glorious coasters to give to friends and family as gifts or sell at craft fairs. 

Dimensions: 90mm diameter x 10mm depth 
This mould takes approximately 50ml of resin to fill. 

We recommend using a clear layer of heat-resistant resin first in your mould, letting that set and then adding more resin with colour, ink, glitter, etc. This helps to boost the heat-resistance of the resin. Remember too that our heat-resistant resin needs at least 7 days to achieve full cure.

Have you tried the alcohol ink drop in a coaster? It's super-popular at the moment! Just search "resin petri art" in your browser's search engine. 

Our silicone moulds can be re-used time and again providing they are looked after well. Keep it in the bag it comes to you in, don't use a flame near the mould (use a heat gun instead) and be careful when de-moulding - try not to scratch the mould with long nails or bend it out of shape too much. 

If your casting comes out dull it could be that the mould has come to the end of its life (or that the mould doesn't have a shiny interior surface). You can keep using moulds that are past their best - it just takes a little more effort. Add a thin layer of resin to the casting or use polish and a cloth to bring up the shine.
