 During this time, a solution of 50% camphor in alcohol is added, which then changes the macromolecule structure of nitrocellulose into a homogeneous gel of nitrocellulose and camphor.The chemical structure is not well understood, but it is determined that it is one molecule of camphor for each unit of glucose.After the mixing, the mass is pressed into blocks at a high pressure and then is fabricated for its specific use.
