Steam bending

Steaming is a method of woodworking. It serves as a simple method to refine wood.

In enclosed spaces, such as lignin sugar, gum, tannins are decomposed in sägefallenden wood by steam. In order not to change and weaken the wood fibers, the temperature must not exceed 100 ° C. The steam should be supplied at the beginning in a small amount in order to gradually heat the timber and to make the pores of the penetration of the steam susceptible. After about 12 to 15 hours, the steam valve can be fully opened until after shut off leaking fairly clear water. After up to 80 hours, the timber is taken out and dried. The steaming time is sometimes dependent on the strength of the wood.

Steamed wood work less susceptibility to crack and warp decreases. Some types of wood, such as beech, pear, maple, cherry and walnut, discolor evenly in the process and need not be specially stained.

The subdued wood can be bent easily and retains its shape after it has cooled and dried. Beech and red oak are considered the least problematic in terms of the types of wood timber deformation in Bugholzverfahen. However, other woods such as ash and walnut are available for this.
