[Ravensfort] Raven's Fort red ochre

[doug bell]

Oils are used in modern paint with clay pigments but I don't know how
far back in history that goes.  Oil is the solution for the particles so I
doubt the color would change much.  Clay minerals are molecules shaped
like flat dinner plates.  Other molecules, like water, will fit in between them and give
clays their properties.  

Clays are remarkably useful substances throughout history.  

You get various pigments from clay minerals by drying to remove the water, heating them,
or reacting them with other chemicals and metals.

Cinnabar is mercuric sulfide.

The artists and alchemists didn't know the chemical formulas but they know 
what you got from mixing substances and could follow a recipe.

Magnus
who as an alchemist is fascinated by Hydrargyrum but has enough modern sense
to stay far away from it.












Would it change differently if oil was 
used instead of water?
