Title: Gray-Brown Chemical Stain In Southern Hardwoods

Abstract: Sapwood chemical staining of southern hardwoods has created a serious problem to manufacturers of dimension lumber, flooring, and specialty items which require bright finished material. In the spring when the humidity is high and drying conditions are poor, this stain has shown up extensively. The stain can be identified by a simple acid test, but its control is more difficult . Steaming, low temperature drying, forced-air drying, or immediate kiln drying may be the only present means of controlling chemical stain.
