The early years - home- and trade-made paintsDuring the 19th, and into the early 20th century, there was virtually no industrial development of surface coating technology in Australia. House paints ranged from crude water based mixtures to oils mixed with white lead. Paint manufacture was a cottage industry and recipes such as boiled seaweed and lime, Murray mud and lime, egg white gum and zinc oxide, made up on the spot, abounded.
Clear lacquers were based on heat-bodied oils or crude varnishes, formulated from either natural resins such as shellac or yacca gum dissolved in alcohol, or from oil by cooking it with fossil resins e.g. Congo gum.
No coloured pigments were mixed or manufactured in Australia. Those used included green copper hydroxide, naturally occurring red and yellow iron oxides, and Prussian blue, all imported. These pigments were dispersed in oil as 'colours in oil' and were used by the painter's apprentices to tint white lead/oil or zinc oxide/oil bases.
The earliest patent for a paint invention lodged in Australia, came from one Edward McFie, retired Master of Marine of Tasmania in 1904.
At the turn of the century a working man had to work three days to earn the cost of a gallon of paint, so people made their own. It was not until the 1920s that prepackaged distempers, called kalsomine, consisting of whiting mixed with glue or casein, became available in Australia.
