The aventurine is a special type of the crystalline glaze in which the separation of isolated individual crystals in the magma gives rise to the characteristic appearance of flitters or spangles suspended in a glass. The glazes may exhibit all degrees of crystallization from a few minute crystals to crowding of the magma with crystals, thus forming a matt texture, or in extreme cases a rough unsightly surface. Iron is most commonly used for this development, although chrome, copper and uranium aventurines have been mentioned in literature. In this investigation, we are reporting the results obtained by various students who have participated in our program of a rather extensive study of these glazes. Some of the data have been had from class exercises, other portions have been the results of investigations conducted for theses.
