When nitronium tetranitratoaluminate is sublimed it can form anhydrous aluminium nitrate. Brilliant opaque monoclinic, or rhombohedral, crystals sublimed as a result. The small hollows and pits formed as the ice evaporated (sublimed). Another option is to use sublimed magnesium or magnesium anthracene. The iodine can be sublimed by mild heating. Many phthalocyanine compounds are, thermally, very stable and do not melt but can be sublimed. They are less thermally stable and often can not be sublimed. Many argued that the more times calomel was sublimed, the purer it got. The Sublimed and Meritorious Fourth Degree was organized in 1917.
