Steaming (wood)
Steaming is a woodworking technique . It serves as a simple process to refine wood .
Goal setting
Steamed woods work less, the susceptibility to tearing and throwing is reduced. Some types of wood, such as beech , pear , maple , cherry and walnut, discolour evenly during this process and no longer need to be stained separately.
The steamed wood is easy to bend and retains its shape after it has cooled and dried. Beech and red oak are the most unproblematic types of wood in the bentwood process. But other woods such as ash and nut can also be used for this.
Procedure
In closed rooms, a steaming chamber or steaming pit, lignin components such as B. Sugar, rubber, tannins in lumber decomposed by means of water vapor . In order not to change or weaken the wood fibers, the temperature must not exceed 100 ° C. The steam should be supplied in small quantities at the beginning in order to gradually heat the wood and make the pores more receptive to the penetration of the steam. After about 12 to 15 hours, the steam valve can be opened fully until clear water comes out of the tap. After up to 80 hours, the wood is removed and dried out. The steaming time depends on the thickness of the wood.
