Georgetown Flint Cleaned Nodules 5-9+ inch -10 lbs
Cleaned of visible waste and checked to be good stone, these mostly-raw nodules are great for knapping large daggers, spear points, knife blades, or spalling down to make multiple points. This material does not require heat treatment. Sold in 10 lb lots.
These raw Georgetown Flint nodules have been cleaned of visible waste and checked to make sure they are quality material. The size of these nodules is great for large daggers, axes, and blades. The material in this natural form can also be reduced down by spalling into smaller spalls/flakes for making multiple blades/points from a single nodule. 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 a particularly 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 it’s 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.
We are selling these natural cleaned cobbles in 10 lb lots because of the sheer size/weight of each piece. Each 10 lb lot will include 2-4 nodules of varying size and thickness.
We strive to provide the cleanest, blemish free knapping material within our means. On some material 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. Material this large will require a spalling hammer, or extra large billet to process. 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 spalling hammer, or extra large 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 or brass billets instead of a copper bopper.
