A real gem, our Agate Geode Cut Out Coaster Moulds will certainly make your resin creations look stunning, just like a real geode! These gorgeous homeware moulds will make perfect decorative pieces for around your house that all your friends will envy.

First, brush the inner edges with our liquid metal powder to take your creation to the next level. Next, add heat-resistant resin and embed dried botanicals and mica flakes for impact. Finally top your creation with a fine sprinkling of Aurora Dust, allow to set before adding a final clear layer of resin - Working in layers will help ensure your pretty florals sit up front and central when you turn the coaster out. Voila - a unique one of a kind creation made by you.

If you're using these moulds to make coasters, we recommend that you add a 3mm thick clear layer of Heat-Resistant resin first in your mould. Let it set and then add more resin with colour, ink, glitter, flowers etc. Once turned out, what was the bottom will be the top and heat-resistant up to 90oC! Remember that our Heat-Resistant resin needs between 14-21 days to achieve full cure, so don't place a hot cup on it too early.

If using to make a JESMONITE coaster, remember to seal the coaster before use with our Protect-It sealant to make it less porous.

How to look after your new mould: top tips from the Resin8 team

Our silicone moulds can be used multiple times - to get the very best resin results it is important to care for them perfectly. Keep your mould in the bag it comes to you in and store carefully moulds do not like to be stacked or kept contained in a box with other items, this will result in the mould losing its shape. Moulds that are more complex to demould from will not last as long as straightforward, plain moulds.

It is best to use a heat tool such as an embossing craft gun to rid bubbles from your creations, naked flames can damage the outer edges of your mould. Take extra care when de-moulding your creation, pay special attention to not scratch the interior of your mould with long fingernails.

Any residue left in your mould once you have finished using it can be brushed out with a soft bristled brush such as a watercolour paint brush. Do not use sticky tape to de-tack dust, fluff or glitters - doing this will remove the interior shine within your mould.

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. 

You might like to consider using moulds that have past their best for another exciting craft. How about exploring the wonderful world of JESMONITE? Resin-tired moulds make excellent moulds for working with JESMONITE​​​​​​​.  You can find more about this wonderful composite here.
