By several methods, manganate of baryta may be obtained either as an emerald-green, a bluish-green, or a pale green.    From Wordnik.com.  [Field's Chromatography or Treatise on Colours and Pigments as Used by Artists] Reference

Now, however, this difficulty has been partly overcome by so preparing the manganate as to prevent fusion, and to keep it in a spongy state, which gives very high results, and the substance being practically everlasting, the cost of production is extremely low.    From Wordnik.com.  [Scientific American Supplement, No. 795, March 28, 1891] Reference

On allowing the solution to stand exposed to the air, it rapidly becomes blue, violet, purple, and finally red, by the gradual conversion of the manganate into the permanganate of potash; and on account of these changes of color the black mass has received the name of mineral chameleon.    From Wordnik.com.  [Scientific American Supplement, No. 401, September 8, 1883] Reference

It consists of passing alternate currents of steam and air over sodic manganate heated to dull redness in an iron tube; the process has never been commercially successful, for the reason that the contents of the tube fused, and flowing over the surface of the iron rapidly destroyed the tubes or retorts, and also as soon as fusion took place, the mass became so dense that it had little or no action on the air passing over it.    From Wordnik.com.  [Scientific American Supplement, No. 795, March 28, 1891] Reference
