Green decomposition of organic dyes using octahedral molecular sieve manganese oxide catalysts. Journal of Physical Chemistry A, 113, 1523-1530. 

Some oxide-type minerals have been found to luminesce when irradiated. A simple example is ruby (aluminium oxide with chromium activator), which emits bright-red light. The phosphors are incorporated into colour television screens to emit the colours blue (silver-activated zinc sulphide), green (manganese-activated zinc orthosilicate), and red (europium-activated yttrium vanadate). 

Common chemical properties The alkali metals are so chemically reactive that they are never found free in nature. Sodium and potassium react explosively with water to produce hydrogen gas. The alkaline earth metals are not quite as reactive as the alkali metals. The alkali metals react with water but not explosively. The transition metals are generally the least reactive of all the metals. However, when they combine with other elements, they form a large variety of colored compounds. Chromium oxide is green, titanium oxide and zinc oxide are white, manganese oxide is purple, and iron oxide is ochre. 

Manganese oxides MnO is grey-green Mn02 is black Mn203 is black. 

The nearly colorless glass fragment (object 1) has essentially the matrix composition. The slight green tint probably comes from the very small amounts of iron, copper, and manganese oxides present. 

Pigments for use with concrete in the UK should comply with BS 1014. Carbon black, red, yellow, brown and black iron oxides, black manganese oxide, blue cobalt oxide and green chromium oxide are used.
