Linseed oil paint with iron oxide minium is an excellent rust protector

For many years now, we have produced linseed oil paint minium as an anti-corrosive paint and received very good response from our customers. The first time we read about minium was in the book Måleri (Painting) from the Craftsmanship Association. On page 37 in the second edition printed in 1934 you can read the following: ”Minium has very good coverage and is chemically neutral, which is why it is very well suited as an anti-corrosive paint. When used with oil, the minium also preserves wood.” This piece of information was the only one available to us when we started experimenting with producing an environmentally friendly alternative to the toxic red lead minium. The pigment we use comes from Spain and is a clay earth pigment called hematite. The structure of the pigment makes it form a pattern like fish scales in the paint film. When mixed with linseed oil, it is very difficult for water to reach the underlying iron. Graphite (lead) is traditionally a very commonly used pigment for painting metal outdoors. Graphite is not an anti corrosive in itself; the iron must first be primed with minium. Graphite is mentioned in literature for the first time in 1604. It is a mineral modification of carbon with a metallic luster and is used for manufacturing pencils. Our graphite linseed oil paint has a slightly different consistency compared to our other paints, due to the characteristics of the pigment. Graphite easily smears onto other surfaces and therefore should not be used on chairs or seats.
