Summary
Dark glass jar containing potassium bicarbonate previously used at Pigment Manufacturers of Australia (P.M.A.) in Laverton, Victoria in the late 1980s. In its natural state potassium bicarbonate is a non-toxic white solid. It can be used in baking to act as a leavening agent, similar to baking soda, in agriculture where it can effectively serve as a fungicide, as well as an ingredient in dry chemical fire extinguishers.
Pigment Manufacturers of Australia (P.M.A.) was established at Laverton in 1961. It manufactured two main classes of pigments, azo and phthalocyanine, which were sold mainly to the local ink and paint markets. P.M.A. closed down in 1990 due to various economic and environmental factors.
