For those of you making your own oilcloth, or using linseed oil on wooden implements used for food, it is wise to note that the "Boiled Linseed Oil" you purchase is in fact NOT BOILED!!! Instead the manufacturers have added poisonous chemicals to aid the drying process!!!
ONLY therefore ever use RAW LINSEED OIL. It will take longer to dry if you don't boil it first, but it is safer. Make sure you read the contents label even on raw linseed before purchasing.
