125 g Polymer Oven Bake Clay Hard After Bake

Description

Preheat the oven to 120-130 degrees C (248-266 degrees F)Place your sculpture on an oven tray and bake for 30 minutes. Carefully remove from the oven and let it cool .We’d also suggest baking your polymer clay on a standard setting (not fan-forced). The reason for this is that the fan can cause the temperature to spike, making it harder to control the heat ,Baking times may vary, but in general we’d recommend 30 minutes of baking for every 6mm of polymer clay thickness. It’s also a good idea to do a test run with some spare clay before you put your finished project in to bake. Here are a few examples to help guide you:6mm thick: bake for 30 minutes12mm thick: bake for 1 hour18mm thick: 1.5 hours .Once your clay is baked, we’d suggest turning the oven off and opening the door to allow your sculpture to cool slowly. This will help prevent cracking due to sudden temperature changes. Once it’s cooled to room temperature you can take it out and admire your handy work.
There are a couple of reasons your clay may crack after baking, but the good news is that we’ve got a few tips you can try.Under-baking : Sometimes under-baking polymer clay can cause it to crack. The chances of this happening can be reduced by following the suggested baking times (120-130 degree c) .Over heating:  If polymer clay is too close to the element in your oven it can heat up too quickly and result in cracking. Try to place your sculpture in a spot that will get a nice, even flow of heat and you should be able to avoid this issue. Cooling too quickly:  If polymer clay cools too quickly after baking it can crack. The simple solution is to leave it in the oven with the door open to let it slowly to room temperature.
