We've compiled a bunch of frequently asked polymer clay questions below. If you can't find your question here, feel free to email us at firstname.lastname@example.org. We're always here to help!
Can I bake polymer clay in my regular oven?
Yes! Polymer clay is non-toxic so you can bake it in your home oven - just follow the packet directions (if you are to accidentally burn it we recommend cleaning your oven). Many polymer clay artists also use toaster ovens and some even use air fryers!
Do I need to bake the clay straight away?
No. If you can't bake your clay straight away, simply keep it in an airtight container in a cool dark place.
Do I need an adhesive to layer clay?
If your clay is unbaked, you can place clay on top of clay and the pieces will bind when they bake. Just be sure to stop air pockets from forming between layers. You can lightly roll the clay pieces together to ensure there isn't any trapped air. If your clay pieces are already baked, you will need to glue your layers together with an adhesive.
Do you have to seal clay?
You may want to sand or buff your pieces, or seal with a resin, to achieve a certain finish but this is not necessary. Polymer clay is hard wearing and water resistant. We do recommend sealing your pieces if you incorporate another medium, such as when you add gold leaf to your clay.
How should I store excess clay once the packet is open?
Once your clay packet is opened, we recommend keeping it in a sealed ziplock bag in a cool, dark place.
How long does polymer clay last?
If you store your clay properly, it can last for well over a decade!
What do I do with my clay scraps?
Colour mix! Choose a handful of clay scraps that you think will work well together and combine them. We love seeing what colours our scraps make!
Can polymer clay get wet after baking?
Yes. Polymer clay is water resistant.
Is polymer clay non-toxic?
Yes. Polymer clay is non-toxic.
Are there certain polymer clays I should use over others?
We use Sculpey clay. Sculpey Premo and Souffle are hard wearing after baking and ideal for jewellery. Some clays can become brittle after baking (such as Sculpey III) so are not suitable for jewellery.
How do I stop getting bumps in my clay?
Bumps and air bubbles can occur in your clay during the conditioning phase. If you fold your clay over and trap air in between the layers, it is difficult to remove them and makes for a bumpy finish. Tear or cut your clay instead of folding and pop any air bubbles you see as you go.
Why is my clay cracking?
There are three main reasons why your clay is cracking. The first is underbaking. Make sure that you are following the instructions on your clay for baking times and temperatures. The second is using the incorrect clay type. As mentioned previously, some clays are more brittle than others once baked. The third is if you have water or moisture in your clay. If you wipe down your surface to clean it, make sure it is dry before using it for clay.
How do I stop clay from getting stuck in my cutters?
There are a few different methods you can use to stop clay from getting caught in your cutters. The smaller or more detailed the cutters, the more careful you will need to be when stamping them out. See our Cutter Use and Care page to learn about the burnishing, cornflour and plastic wrap methods.
