About

Iron Oxide (Red) Fe₂O₃

Synonyms: Haematite, ferric oxide

Synthetic version 4511 is more finely grained, but even then speck-free pigmentation cannot be guaranteed. Glaze producers resolve this by wet ball milling their glazes so the pigment is ground very finely into the glaze. Sieving through a finer mesh will reduce the specking but probably will not prevent it.

Raw colour of powder: Rust Red

Colour responses after firing:

Painted onto clay: Brown-black
Painted onto biscuit: Brown-black
Painted onto unfired glaze: Brown (honey), black, green Mixed into glaze: Brown (honey), black, green
Reduction firing: Brown (honey), black, green, pale blue (celadon)

Please note that these are the typical results,but combinations of oxides will produce different results depending upon the relative percentages of each used and the firing conditions in the kiln. Also the underlying body colour will influence the resulting colour.
