Spread the love with this simple but beautiful Heart Coaster Mould. This flat heart mould has a smooth semi-shiny interior and is used to make a gorgeous heart-shaped coaster or piece of art.

Dimensions: 10.2mm x 8.5mm x 6.6mm deep 
This mould takes approximately 45ml of mixed resin to fill. 

If you are making coasters, we recommend using a 2-3mm layer of clear heat-resistant resin first in your mould. Let that set for 7 days and then add more heat-resistant resin with colour, ink, glitter, etc. This helps to boost the heat-resistancy of the resin. Remember too that our heat-resistant resin needs at least 21 days, before a hot cup is placed on it, 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.
