Manganese Oxide

Alternate Names: MnO, Manganese(II) Oxide

Oxide Analysis Formula
MnO 81.58% 1.00
LOI18.42%
Oxide Weight 70.90
Formula Weight 86.91

Notes

If manganese is being used in glazes fired below 1080C, then it should be considered as composed of 100% MnO2 (Manganese Dioxide), if above it should be taken as 81.5 MnO (Manganese Oxide).

Typecodes Colorant
Metallic based materials that impart fired color to glazes and bodies.
Typecodes Generic Material
Generic materials are those with no brand name. Normally they are theoretical, the chemistry portrays what a specimen would be if it had no contamination. Generic materials are helpful in educational situations where students need to study material theory (later they graduate to dealing with real world materials). They are also helpful where the chemistry of an actual material is not known. Often the accuracy of calculations is sufficient using generic materials.
Materials Manganese Carbonate
Materials Manganese Granular
Materials Manganese Dioxide
Temperatures Manganese oxide melts (1785C-)
