Uncleaned heat treated Keokuk chert spalls straight out of the kiln. The chert at this stage has not been cleaned of waste like our #1graded spalls. Large variety of sizes and some odd shapes; uncleaned rock will have some waste. Great practice material for beginners and advanced knappers. Sold in 5lb lots.

Lightly graded Heat Treated Keokuk Spalls without our final cleaning stage performed.  Sold in 5 lb lots. Spalls range from 4-7 inches.

Keokuk Chert most often ranges in color from grey, pink and tan with occasional bands of red and purple. Keokuk is a dense, high quality chert found in parts of Oklahoma and surrounding areas.

Next to impossible to knap raw out of the ground, we digitally heat treat all of our Keokuk within close tolerances in an effort to produce the most consistently knappable stone achievable.

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.
