50% (m/v) gum arabic in water with 5% glycerol (v/v) then added. The latter slows drying rate, fills in holes at surface and on platform. I am interested in the "thin films" that form under testing conditions. Glycerol will aid in preventing blistering . These films can be studied by FT/IR. UV changes can also studied this way. The dried paint is very resistant to water. This is one of my research areas as a chemistry professor in the USA. Chemistry and art have a long time traditional relationship and it continues.
