Abstract
A wood substrate or member is included, having an increased density with respect to natural, untreated wood. The process includes drying the wood prior to application of heat and pressure, which are controlled to reduce or eliminate color change on a surface of the wood member where heat and pressure are applied.
Claims17
A method for increasing the density of a wood member including:
- (a) preheating a wood member, wherein the preheating is for a time sufficient to obtain a core temperature of the wood member of about 250° F. to about 500° F.;
- (b) optionally, applying water to a surface of the wood member;
- (c) after obtaining the core temperature of the wood member of about 250° F. to about 500° F., applying pressure to the wood member for a press time, wherein heat is applied during applying pressure to maintain the core temperature of about 250° F. to about 500° F.;
- and
- (d) providing a post-treatment conditioning of the wood member.
