Abstract
The disclosure concerns a hard multi-ply laminate, at least two of the plies comprising primarily wood fibers compressed with a plastic, and an intermediate ply of a different chemical composition than the wood fiber plies, and top and bottom plies of substantially the same physical performances to avoid warping. An adhesive is applied between each of the plies and all the plies are compressed to form a hard laminate. An edge of the resulting board is shaped to form an artistic configuration, and the edges are coated with a moisture barrier. Thus the resulting hard laminate boards with a sculpted edge can be used directly for table and desk tops, shelving and the like without the addition of an edging strip.
