A forced air drying oven can efficiently remove moisture from the chamber—the more air in the chamber, the faster the drying process. You can also adjust the drying rate through the exhaust ports built into the equipment. Forced air ovens can be used for processes to eliminate germs and harmful bacteria on items.

Air Dry Clay. In general, air dry clay is a lot softer and easier to work with. It doesn't really need to be warmed up to be soft enough to roll out and it is very easy to cut. Because the air dry clay is softer, it takes stamped textures very well. All the stamps I tried came through very clearly and with all the details intact.
