Materials used:


Measure out equal parts of resin and hardener into your plastic mixing jug, starting with your hardener. You shouldn’t need more than 400ml of fully mixed resin, therefore 200ml of hardener and 200ml of resin.

Combine and mix well for at least 5 mins.


Split the resin between 6 mini silicone cups and colour 5 of them to your liking leaving 1 clear.I coloured mine as follows:

  • Cup 1 - Glittery teal
  • Cup 2 - Antique gold
  • Cup 3 - Deep teal
  • Cup 4 - White
  • Cup 5 - A mix of 3 glitters
  • Cup 6 - Clear


Now add each colour to each of your 4 molds. However, don’t use up all of your resin in one go. Start with just one layer.

I like to start with the center colour and then the outside colour and carry on from there. Add rings of colour in any order you like.

To see how I filled my coaster molds, check out my YouTube video using my links in this post.


Pop some bubbles using your blow torch and then blend your rings using your heat gun.


Repeat the earlier steps adding more resin rings. Then add the clear resin to spread and blend all the colours.


Blend and pop some more bubbles before leaving your coasters to cure for at least 12 hours.


All that’s left to do now is demold and fall in love! It’s that easy!

    I'm about to watch your you tube video, but would like to know if you can see light through these? By the way, absolutely gorgeous!!

    Wonderful. How many coasters do you get out of the batch of 1/2 c hardener and 1/2 cup resin?

  • Cary Cary on Jan 28, 2020

    What else could you use for the molds? The ones you use seem very project specific.

    It might be cheaper to buy the coasters because the things you need to make these are very expensive.

      These would make great gifts. When you tell everyone that you made them yourself, there will be a huge whooo hoooo factor!!!!!
