ABSTRACT:
Mineral or wood fiberboard is provided with a disrupted or embossed decorative surface, painted overall with a paint containing yellow pigment grade ferric oxide pigment, and the high areas contacted with a heated surface at a temperature such that the ferric oxide pigment is heated to drive off the water of hydration and convert it to a red ferric oxide, thus achieving a two-toned decorative painted board product.
