My friend, Warren was busy right to the end. He left behind well over 150 preforms. His method of making points was to use a tile saw to cut rough shapes. If the preforms were hard rock, he would then heat treat the stone (this step is not needed for obsidian). During the winter months, his unheated shed freezes making his saw unusable. For every batch he would work, he set aside three so he could continue working during the winter. If you are a flint knapper, and would like some new material to work with, or if you think you would like to learn but don\'t want to buy a large quantity of stone these preform packs are ideal.
3.25 x 1.0 x 0.4 inches, mahogany obsidian from Oregon; 3.25 x 1.4 x 0.48 inches, amazing double flow obsidian from Oregon; 3.4 x 1.3 x 0.47 inches, gray obsidian from California; 1.69 x 0.7 x 0.32 inches, Idaho jasper; 1.71 x 0.81 x 0.29 Utah agate.
The individual photos showed the pieces wet in order to show the color better. The group photo shows the pieces dry. Because of the microabrasions from the tile saw the pieces look dusty when dry. After flaking you will see the shiny surface you expect.
