Baking Tips
Firstly I would suggest that when you’re baking clay get an Oven thermometer, you can set the temperature to 130°C/265°F but the internal temperature can vary considerably resulting in under baked or over baked clay! It takes the guess work out and allows you to get an even bake throughout your pieces!
In addition to the thermometer, When baking, I’d suggest popping some parchment or baking paper down to bake your clays items on, This acts as a nice buffer between the surface of tray and clay so you won’t have to worry about any clay adhering to the surface of the tray!
For larger pieces, you can also create a foil tent to place over the top (Make sure the clay doesn’t touch this!!), this will help with the top getting too close to the oven elements and disperse the heat a bit, as you don’t want the tops to burn!
