Notes
This is a lanthanide rare earth oxide, it is available as a raw pale blue/lavender powder.
It is used as a colorant and acts as a flux.
For information on making vibrant colors using lanthanides visit the page by David Pier linked to this record.
Quote from David Pier: "The oxide is a blue/lavender powder. It is the strongest of these three colorants, giving 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."
