Boiled Linseed Oil - BLO

Many brands of boiled linseed oil now contain so little catalyst that they might as well be raw linseed oil.

Japan drier
This is mixture of one or more catalysts with a solvent. Cobalt lineate, lead, manganese, iron and zinc catalysts may be used. There is no single recipe. These catalysts speed polymerization and hardening of the oil.
MTO
Mineral Turpentine Oil, a thinner
BLO
Boiled Linseed Oil
DBLO
Double Boiled Linseed Oil
napthenic acid salts (naphthenates)
common sources of metal ion catalysts for drying agents (Japan drier). Common sources may contain one or more of the following metals: magnesium, calcium, barium, cobalt, copper, lead, manganese, nickel, vandyl, and zinc.

spontaneous combustion experiment

Pile of paper towels soaked in BLO then drained and then left to sit in a stainlless steel salad bowl.
