Abstract

"An abundant amount of chats and clays of various kinds is available in Missouri. In the mining districts of south-eastern and south-western Missouri enormous piles of gang known as chats have accumulated. The mining companies desire to rid themselves of this accumulation and would dispose of the chats at a very low price. In northern Missouri and in the diaspore district of central Missouri suitable clays could be found which may be had for a small royalty, mining and transportation costs. Some of the requirements for roofing granules are that they have (1) a size limited by 10 and 30 mesh Tyler screens; (2) permanent and uniform color; (3) low reflectivity and low absorption; (4) resistance to freezing and thawing; (5) ability to be wetted and embed well in hot asphalt; (6) such a composition that it will not effloresce due to soluble salt content in moist climates and; (7) especially it should have a low production cost"--Introduction, page 1.
