Our #1 graded and cleaned 3-6 inch Texas Georgetown spalls are ideal in size for producing medium to large points and blades. For larger pieces, please check out our raw nodules product. Georgetown Flint is a highly sought after knapping material because it is particularly easy to knap raw, very consistent, and the cortex often has banded layers which in contrast to the blue/grey color of the stone creates an attractive combination.
Georgetown Flint comes from the Cretaceous Austin limestone/Chalk on the eastern edge of the Edwards plateau in the vicinity of Georgetown, Texas. The Georgetown material occurs in a narrow range of grayish colors, of which the steel-blue/grey glassy translucent variant known as "Georgetown Blue" is the highest quality for knapping. In fact itís probably one of the best quality materials anywhere in North America and is highly sought after. We have obtained a limited amount of this high quality material, and will be offering it while supplies last.
Ordering 1 pound of this material will not ensure that you will get a single 6 inch spall unless as a special request. Most often a one pound order will contain two pieces of stone in the approx 4 inch range. To make certain you receive the full range of sizes of this material you will need to order multiple pounds or purchase a flat rate box of material.
We strive to provide the cleanest, blemish free knapping material within our means. On some spalls however, blemishes do get past us because not all defects are evident at first or even second inspection. In efforts to avoid defects as much as possible, we remove a few flakes via percussion to ensure that you do not pay for large amounts of waste.
Large knapping material requires large billets. Attempting to knap large stone with too small of a billet will damage the billet and not produce sizable thinning flakes early on in the process as needed. If you are graduating to this size material from one of our kits, we recommend adding a large copper percussion billet to your order. Texas material tends to be a bit more dense than heat treated chert. Depending on the size material being worked, it may be advisable to use solid copper billets instead of copper bopper billets.
