Rublev Colours Genuine Japan Drier - 2 fl oz

The name refers to “japannning,” a term for drying oils as an imitation or substitution for urushiol-based Japanese lacquer. In the nineteenth century, Japan driers often were made with lead and manganese in a base of linseed oil, turpentine, and natural resin. The resins used were copal, dammar, rosin, and shellac. Today, most Japan driers consist of manganese in a base of linseed oil and mineral spirits.

Manganese is a primary oxidizing (active) drier. Used alone and in thick paint applications, it tends to cause wrinkling. Manganese is often combined with lead, zirconium, calcium, or a combination of these metals as a drying initiator.

Lead is an effective auxiliary drier when used in conjunction with active driers, such as manganese. Lead promotes the through drying of the paint film. It improves the action of manganese drier, is used in conjunction with it, and assists in the “through dry” of oil and alkyd paint.

Directions
