Swedish red, iron-oxide pigment
Derivation
Original Falun Red was a
byproduct of copper mining
and consequently had a
high heavy-metal content.
Today, it is increasingly
being replaced by an iron-oxide pigment that is nearly
identical in color, free of toxic matter and has a similarly
effective protective function. In a water or linseed oil emulsion,
it easily becomes a high-yield, breathable, natural
color that protects wood from UV rays and pests.
Use
It defines the landscape of Sweden: The warm rust color of
wooden barns, houses and churches not only blends harmoniously
with the green of the natural surroundings, it is
also an effective wood protector.
Recipe suggestions
Red protective coat for exterior walls (the oldest color of
Scandinavian exterior paint): Pine oil + 10-20% iron-oxide
pigment. Fertility approx. 3-5 qm/l.
Water-based red paint: 10 l water, 750 g white or rye flour,
3 kg iron oxide, 300 g green vitriol (iron (II) sulfate (can be
obtained in pharmacies), 1 l linseed oil, a bit of soft soap.
Mix the flour with 2 l water until there are no clumps.
Bring 8 l of water to boil. Stir the flour mixture into the
boiling water and continue to boil for 15 minutes, stirring
continuously. Add the iron oxide and cook for a further 15
minutes while stirring. Add the linseed oil and soft soap (as
emulsifier) and cook for a further 15 minutes while stirring.
After it has cooled, it may be used (or thinned).
1 liter yields ca. 3-5 m²/l.
