This flat Circular Cut Out Agate Geode Quarters Coaster mould has a smooth, shiny interior and can be used to make four coasters, which fit together to make a large circular placemat. Use our heat-resistant epoxy resin (which can withstand temperatures of up to 90oC) to fill this unique mould.

Dimensions: 210mm diameter x 210mm x10mm depth.
This mould takes approximately 200ml of resin to fill. 

If using to make resin coasters, 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.

If using to make Sculpt & Cast coasters, remember to seal the coaster before use to make it less porous. Use specific Sculpt & Cast pigments to colour the material.

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.
