Our German suppliers have been making wood pulp bannetons since the 1920s. Wood pulp is obtained from fresh spruce wood from local forests, which is free of any chemical additives and is produced in a purely physical way.
The fresh tree trunks, which come from sustainable forestry, are pressed against rotating stone rollers while being supplied with water. The wood structure is broken up and a fiber material is created from molecules of cellulose attached to one another. All other wood components, such as lignin, which is a natural wood adhesive, are retained.
You may recognize this by the light yellow-brown discoloration of the shape, as lignin is responsible for the yellowing caused by heat during drying or by sunlight. This yellowing is therefore not a defect but evidence of the natural state of the wood pulp used.
Water is used to produce a pulp from the wood pulp.We have a separate pressing tool for each bread pan into which the pulp is filled.Under strong pressure, the water is pressed out of the fiber pulp in the pressing tool and the fresh bread form is created from the compacted fiber material.
During the subsequent drying process, the cellulose fibers cross-link and knot and thus give the shape its mechanical stability.After drying, the rough edges of the molds are sanded and a quality control is carried out, after which the molds are ready for dispatch.
