Rare Earth Kit

Rare Earth Sample Kit

10 grams of each erbium oxide, neodymium oxide and praseodymium oxide 

Erbuim oxide 

This is a lanthanide rare earth oxide, it is used in ceramics as a stable pink colorant at high temperatures and can also have an opacifying effect.

Neodymium Oxide 

This is a lanthanide rare earth oxide, used as an aqua colorant and also can act as a flux.
Neodymium Oxide gives a good aqua color in most glaze bases at 1-2%.
At 4-7% it gives a pleasant lavender/grape color that appears as a different color under different artificial light sources.
It is very strongly affected by iron, particularly in oxidation, giving a reliable perfect neutral transparent gray.
Avoid trace iron impurities to achieve the brightest blue and lavender colors.

Praseodymium Oxide 

This is a lanthanide rare earth oxide, it gives a small range of vibrant lime green colors in oxidation and reduction at concentrations of 5-8%.
In small amounts (<1%) in reduction with a trace of iron, gives a bright spring green color.
