Bake TLS at 275 degrees F (130 degrees C) for 15-20 minutes. TLS can be baked at 300 degrees F (149 degrees C) to increase transparency and intensify transfer image, however this is not recommended when TLS is combined with solid clay.
Overheating polymer clays will result in blackening and the release of irritating gases including hydrogen chloride. Use an oven thermometer and timer to assure that your creation is not overheated.
Polymer clay can be baked in a home oven, however many polymer clay enthusiasts use a separate toaster or convection oven dedicated to polymer clay baking. Another option is to use a dedicated, inexpensive roaster pan (speckled enamelware) with a lid to bake clay inside your home oven. Another, even cheaper option is to take two aluminum foil baking pans: invert one over the other, and clothespin them shut. Voila, a baking container!
TLS has more of an odor when baking than solid Sculpey clays. Although polymer clay is not toxic, it is important to always bake clay in a well-ventilated area.
In thin layers TLS bakes to a translucent finish. TLS can be applied in layers and be re-baked after each layer. Solid clay items can be baked several times. TLS can also be wet sanded and buffed as long as it is not too thin.
