Step 1: Roll Out Your Clay
Grab a good chunk of clay and begin to roll this out with a rolling pin. You can use 2 pencils either side when the clay has been rolled out a bit to help the clay have an even surface.
Step 2: Cut Out the Coasters
Use a circular cutter or the open end of a large cup to cut a circle out of the clay. Place a mug or glass on top to ensure that that the coaster is big enough. Then slice around the circle to give the look of the rough edge, for the geode style.
Once you're happy with the shape, leave to dry, the length of time will depend on the thickness of clay and how big the coaster is.
Step 3: Sand and Paint
Once the coasters are completely dry, sand them down. Don't forget the sides as well! Wipe off any excess clay dust from the coasters once you've finished sanding down.
You can now start painting, I like to use a white base as a primer before painting over this. I used acrylic paint as this is easy to work with and dries quite quickly. Choose 2 or 3 colours and paint these on the coaster in wonky circles. You can add more of one colour and less of the others. Use the darkest colour to paint around the edge. Using a gold paint, paint the outer edge of the coaster all the way round.
Leave to dry.
Step 4: Glaze
Using triple thick, or a similar product, paint on the glaze, you'll need to leave this to dry for up to 24 hours depending on how thick you paint this layer on. You'll want a fairly thick layer as drinks full of liquid can be quite heavy and you'll want it to be durable enough.
Once the glaze has dried they're ready to use!
