Obsidian/Dacite Small Spalls Mix is a 4 lb. lot of select smalls for arrow point makers. Includes black obsidian, a natural volcanic glass, and dacite, a grainy, gray variety of obsidian. Size ranges from 2 to 3½ inches, graded spalls and flakes with good thickness to width ratio. Purchase this material when you need smaller pieces to work and get more spalls per pound. Use a percussion billet to reduce into preforms for pressure flaking.
