ABSTRACT:
A steel caul for forming wood panels is sandblasted to roughen the contact face thereof. The process of roughening the face results in a multiplicity of minute indentations in the surface of the face which function to capture and retain therein carbonized materials which are produced when the caul is employed to press panel products, thereby extending the period which the caul can be used without the need for cleaning carbon deposits from the same.
