Longer baking will NOT burn your clay. Longer baking will also lead to stronger clay projects. If your clay is burning, the temperature of your oven is too high. That being said, longer bake times can cause some colors of polymer clay to darken.
How do you know when clay is done baking?
Bake for 15 minutes per quarter inch of thickness. For example, a piece of 1/2″ thickness should be cured for 30 minutes. To test the curing, try pressing the tip of your fingernail into the bottom of your piece after it has cooled; it will leave a mark but will not actually enter the clay.
Can you over bake oven clay?
If you overcook your clay the only way to fix it is to cover it up or sand it off. You can hide browning by adding another layer and rebaking or painting over it. Be warned, sometimes sanding doesn’t work because the scorch can go all the way through. So getting baking right the first time is important.
Can you bake polymer clay too long?
What happens if you bake polymer clay too long? Longer bake times usually result in a stronger clay project. If you’re running into issues with your clay, check the temperature before suspecting the bake time. That being said, it is possible to bake clay for too short of a time.
Does over baking polymer clay make it brittle?
Sometimes your polymer clay beads will break even after you’ve baked them. If the temperature is too low your polymer clay will not cure properly. Improperly cured clay is very weak and brittle, and susceptible to breaking. Certain polymer clay brands are more brittle than others.
Why did my clay melt in the oven?
Why did my clay melt in the oven? If your clay melted in the oven, it was a type of modeling clay, also known as plasticine or plastalina. And you might be surprised to know that this is a very common mistake. Sometimes this happens because you pick up a bar of modeling clay along with your polymer clay.

What does it take to smooth out polymer clay?
However, if you want to a very smooth surface that is completely free from bumps, marks and fingerprints, there is another simple trick. Alcohol melts Sculpey. We can take advantage of this by dipping a paintbrush in rubbing alcohol and then gently brushing the sculpture until the alcohol dries.
Why is my polymer clay still soft after baking?
Your Polymer Clay Creation Is Still Soft After Baking If you take your clay out of the oven and find it’s still soft, it could be one of two reasons: the temperature was too low, or it wasn’t baked long enough.

Can you harden polymer clay with a hair dryer?
When you don’t want to cure clays that harden at a specific temperature in the oven, you can use a heat gun, hair dryer or heat-embossing tool set to the desired temperature. Place the polymer clay creation on a nonstick surface, such as a piece of ceramic tile or block of wood.
Can you put non hardening clay in the oven?

Why is my clay not hardening?
The right oven temperature is a crucial factor for baking polymer clay correctly. If the temperature is too low, it won’t fully bake and could be too soft, crumble or break once it’s cured. If the oven temperature is too hot, it could burn your polymer clay models.
Does clay melt in water?
If the clay isn’t totally dry, it can be left in water overnight to soften, then it can be re-wedged and re-worked. If it is totally dry, it will dissolve into a soupy liquid.
Do you paint clay before or after baking?

Can you put clay in the oven instead of a kiln?
When firing without a kiln, it may help to pre-dry you clay pieces in a kitchen oven set to 190 degrees F. I set the oven to 190 F. This is NOT firing the pots, but it dries them so they can be fired in an outdoor bonfire or pit firing with less breakage caused by steam explosions.
