In traditional varnish manufacture an open kettle is set over a fire in which copal or other natural gum is heated and dissolved in hot oil. Other ingredients such as driers are added and after cooling the varnish is thinned out to a workable consistency with solvent. It is then clarified by gravity settling, straining or centrifugation.
