This SUPER SHINY round disc mould has not one but 3 petri cavities so you can make 3 coasters at a time! Use our coat-it 1 to 1 resin for coloured wall art, our fill-it slowcure epoxy for crystal clear round discs, and if you want to use this mould to make a large coaster/placemat, remember to use our heat-resistant resin as the final layer (or first layer if you're making them upside down). Easy to demould, this flexible mould gives you plenty of space to make glorious effects with resin and alcohol ink.

Measurements: each petri 95mm across, approx 18mm deep (but you don't have to fill it right up!)
Measurements: entire mould 292mm long, 168mm wide

Each petri takes approximately 100ml to fill, 300ml for all three. 

Made popular by artist Josie Lewis, of Petrified Rainbow, Petri Art combines resin with alcohol inks to create three dimensional splashes of colour with unpredictable results. Called petri art because it resembles the tiny particles found growing in petri dish experiments, this popular technique is simple to get started with as long as you get the basics right.

If you are going to use this mould as a coaster/placemat, we recommend the following: Use a clear layer of heat-resistant resin first in your mould, let that set and then add more 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 7 days to achieve full cure. 

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.
