Firing temperatures for paper clay are exactly the same as the clay body from which the paper clay was made. Some recommend slightly higher firing temperatures.

firing is possible, offering firing and time savings.
There is no physical difference between soft clay and the same clay as a soft paper clay, except the small fibers. Building techniques used with soft paper clay are similar to conventional clay. Dry paper clay is stronger than the same clay without the fiber, enabling thinner, more delicate works.
The inclusion of processed cellulose fiber in the clay enables new ceramic techniques. Joining dry-to-dry paper clay and dry-to-soft paper clay are the most radical new techniques. A new aesthetic has also emerged from combining paper and clay art traditions.
