Dacite is slightly translucent to opaque, with a medium gray to solid black coloring. With a slightly grainier texture than the glassy obsidian, it looks and works more like stone. This is the best recommendation for the beginner knapper because of its ease of workability and little to no flaws. Your purchase will contain 10lbs of premium (Grade-A) spalls that range from 4-7 inches long and are a great choice for the beginner to expert knapper. Stone shown in the picture is an example of what to expect. Actual pieces may vary, a 10lb box contains approximately 7-8 spalls depending on size and weight of each piece. Skill Range: Beginner to Expert.
