ABSTRACT:
The present disclosure includes methods for enhancing hardness and dimensional stability of a wood element. In one embodiment, the method includes placing the wood element in a compression assembly set to a compression temperature between about 365° F. and about 410° F., heating and compressing the wood element without exceeding the species' threshold pressure value to produce a compressed wood product, heating the compressed wood product to a post-compression temperature between about 275° F. and about 350° F., and holding the compressed wood product at the post-compression temperature for about 30 to about 48 hours. The disclosure also includes a wood product having enhanced hardness.
