Information

Make some gorgeous geode art with our Matte Round Agate Placemat Mould! Having a rough, almost druzy edge, this mould gives an authentic and natural look to your finished piece. Use as a placemat, or as a decorative piece to show off your skills.

We decided to add a bit of shine using angelina film in the centre, along with some silver metallic edging paint around the sides. Dried flowers and leaves also make fascinating additions to your piece!

Want a shiny piece instead? Just paint the matte surface of your finished piece with a layer of clear mixed resin . . . and voila!

Finished piece dimensions:

  • 240mm wide, 340mm long
  • 5mm Deep
  • Requires approx. 250ml of resin or 425g of JESMONITE (without embellishments).
  • Pour steadily - your resin will get very hot when curing in this mould!

If you're using this mould to make placemats, 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 90˚C! Remember that our Heat-Resistant resin needs between 14-21 days to achieve full cure, and should be left for 3-4 days before demoulding. Don't be tempted to place a hot cup on it too early.

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.
