Claims
- 1. A process for forming a steel caul to use in forming panel surfaces on panels made of reconstituted wood by pressing said cauls against said reconstituted wood at temperatures of up to about 475.degree. F., said process comprising the steps of:
- a. selecting one face of said caul to form said panel surfaces,
- b. forming a decorative pattern on said selected face, said decorative pattern being adapted to be pressed against the reconstituted wood panels to form the panel surfaces on said panels, and
- c. thereafter, roughening the decorative pattern formed on the selected face of said steel caul by sand blasting said face with number 12-35 sand thereby forming a multiplicity of indentations in said decorative pattern on said selected face said indentations being large enough to capture and retain the carbon materials produced by the use of said caul in forming said panel surfaces, but not being so large as to have a visibly noticeable detrimental effect on the said decorative pattern in said selected face.
- 2. A process as in claim 1 further comprising the step of smoothing said one face prior to roughening.
- 3. A process as in claim 1 further comprising the step of embossing said face with a decorative design prior to roughening.
- 4. A method as in claim 1 further including the step of forming said indentations in a random orientation.
