This highly-purified, chemically inactive coating (supercoating) photo gelatine can be used in daylight. Just stir 40-80 grams into 1 Liter of 40° C. hot water until completely dissolved. It can then be used as a basecoat on highly absorbant surfaces, to minimize the amount of photo emulsion used.
The gelatine can also be used to improve the glossiness of fiber (baryt) paper when using a hot print dryer.
