Double Boiled Linseed Oil has added dryers like lead, cobalt and zinc.Raw Linseed Oil and Danish Oil are lead free.You cannot make Double Boiled Linseed Oil without the addition of dryers therefore it is not meant for food surfaces. These dryers are a combination of Cobalt, Lead and Zinc which helps the product dry in less than half the time as standard linseed oil. Traditionally, lead was added to paints to increase their drying time but nowadays, spirits and solvents are used that give out toxic vapours.If you are worried about lead in the product, we would recommend you use Raw Linseed Oil but then the tradeoff would be much longer drying times.This product has an insignificant amount of vapour as compared to varnishes so it is easier on the eyes, nose etc. Also, the percentage of lead vis-a-vis the volume of the product is in fractions and far lower vs. lead paints. Since this is a concentrated product, a little goes a long way and you can dilute this further with solvents to reduce the lead concentration further. As long as you let the product dry and air out in the outdoors, it is not harmful to the environment or your health.
