Density enhancement and block staining

What is wood density enhancement?

 

Wood density enhancement is an industrial process which improves the mechanical features of the material. Natural corn-starch-based polymers are injected in lumbers under pressure in an autoclave. These molecules are very similar than cellulosis. Once they are in the material, polymerization of thoses elements is activated by kiln drying and the removing of water. The results are particularly striking on softwoods as pine or poplar may be as hard as oak thanks to this treatment.

 

 

What is wood block staining?

 

Wood block staining is conducted in a vacuum/pressure autoclave where pigments are forced into the whole piece of wood. Softwoods would be evenly tinted as hardwoods would get a more shimmering stain. The stain wil remain even after working, cutting, surfacing the piece of wood contrary to a coating. This process is compatible with fire retardant treatment and density enhacement.
