What’s the best clay to use for DIY marble clay coasters?

My absolute favorite clay to use for DIY marble coasters is Sculpey polymer clay. Sculpey clay is a breeze to work with. It’s super pliable, so you can shape it just right, and it bakes up strong, ensuring your coasters will last through countless cups of coffee. Plus, the range of colors means you can easily achieve that classy marble look.

​How to make DIY coasters

1. Take 1/4 of each brick of colored clay and roll each piece of clay into the size of a gumball. Make three more gumballs of the same size using white clay.

If you want a black marble effect, replace the white clay with black clay.

2. Roll out each gumball to form a snake.

7. Using the acrylic rolling pin, roll out the clay on a flat surface until smooth and about 1/4” thick.

It’s always a good idea to make sure you’re working on a nice, clean surface to avoid any dirt or debris getting into your clay.

8. Use a cookie cutter to cut a circle for your coaster. Repeat all of the steps to make more coasters. You can use any shaped cookie cutter to make your coasters – a square or hexagon would work too!

9. Place the coasters on a parchment-lined baking sheet. Bake at 225 degrees for 30-40 minutes. Be sure not to raise the temperature – burnt clay has an awful smell! Use an oven thermometer to be sure the temp is right.

10. Let the coasters cool and then paint over the rough edges with acrylic paint. I chose gold to use, but you can use any accent color you’d like!

You can paint the bottom of the coasters too if you only want the unique marble effect to show on the top.

11. If you want a glossy finish, you can seal your coasters with Mod Podge or another sealant. This step is optional!

FAQs (Frequently Asked Questions) about DIY Marble clay coasters

Can I use air dry clay to make DIY marbled coasters?

Absolutely, you can give air dry clay a try for your marbled coaster project. It’s a fun alternative to polymer clay and doesn’t require baking. Just keep in mind that air dry clay tends to be a bit more delicate than polymer clay once it dries, so handle your coasters with care.

Can I make custom shapes with Sculpey clay for my coasters?

Yes! Sculpey clay is super versatile. Once you’ve created your marbled clay sheet, you can use cookie cutters or simply hand-cut custom shapes for your coasters. Get creative with circles, squares, hexagons, or any shape that matches your decor.

What’s the best way to seal and protect my marbled coasters?

Your coasters have a lovely glossy finish. Simply follow the instructions on your chosen sealant product for the best results.
