Page 58 of the same book refers to sugar quartz is "The sugar quartz is therefore the only pure silica present in commercial quantity in the region investigated. When pure its refractory value is cone 34 (1,810° C.). With the small amount of impurity present its deformation point or refractory value is about cone 32 or 33, that is, 1,780° C." Several other Native American Arrowheads made out of sugar quartz have been found as referenced in www.ArrowHeadOlogy.com, Lithicasting
