a friend of mine gave me some recipes and his recipes have "spanish" iron
oxide which i've never used. Also, one glaze has "iron chromite." i tried
to find out both iron oxides, but my ceramic resouses are limited. does
anyone know more about both iron oxides? also, it may be a good time to
review functions and substitutions of all iron oxides such as red iron, black
iron, yellow iron, spanish iron, iron chromite, and so on... iron exparts,
please help me!

Iron oxide in a recipe should apply to the normal Red Oxide of Iron.
This can be natural or synthetic. ..and as with Black Iron Oxide..(which =
is normally about 10% higher in Iron content) can be variable in =
content. The best technique is ..as usual with our materials..test and =
then buy a reasonable quantity to keep you going without the nuisance of =
having to retest a new supply frequently.If you buy from a regular =
supplier..then make sure they inform you when their source of ANY =
material changes.
I cannot find a reference for pure Yellow Iron Oxide..and wonder whether =
it would be a natural material in the Ochre area and therefore could =
have a clay content and be lower in pigment power.
Yes David..It would be most helpful if all suppliers would add to the =
labelling of all Iron oxides ...the exact Fe content.The behaviour of =
the Iron and any other oxide..can alter with a variation in particle =
size ..(Black Iron is usually not as fine as Red) and gives a reason for =
ballmilling a celadon.

Nubiola inorganic pigments produces very good synthetic iron oxides.
The product number I use is R-5510, red iron pigment red 101. It will
produce great color in reduction or oxidation. =3D20
