Bleached Shellac 250 grams
Dewaxed Bleached Shellac is refined using the Bleaching Process, in which Seedlac is dissolved in an aqueous alkaline solution. The solution is then filtered to remove any insoluble material and the wax, before being bleached with sodium hypochlorite to remove the colour. The Shellac is then precipitated from the solution by adding dilute sulphuric acid, before being filtered, washed with water and dried.
Add 250 grams of Shellac to 3/4 of a litre of methylated spirits and stir, the shellac will dissolve in about 2 hours (stir / shake frequently).
Top up Shellac mixture with 1/4 of a litre of methylated spirits.
