The material is produced by a process in which casein is kneaded and colored and then processed to produce sheets, bars or slabs; these are then treated by immersion in a diluted solution of formaldehyde that causes, with a very slow reaction, the progressive hardening. Finally the material obtained is dried and then can be processed. The production process is therefore very slow (for thicknesses of 2.5 cm it may take up to one year of immersion), moreover, even if the galalite sheets can be hot bent, mould production is not possible, which makes the processing of the material more complex.
