The role of glycerol in addressing surface checking - Summary Report

The role of glycerol in addressing surface checking - Summary Report

This project investigated the impact of glycerol application, during the early stages of drying, to reduce the incidence of surface checks in Australian hardwood timbers.

The project showed that for four out of the five species investigated, surfacing checking was educed by well over 10% by the application of glycerol in the early stages of drying. The glycerol had generally penetrated into the timber to a depth of between 1-3 mm at the end of drying and conditioning. This outer glycerol penetrated layer of timber will most likely be machined off during final dimensioning.
