These spalls are selected flints and cherts of Edwards Plateau silica. Spalls have been heated to 450F, when needed. Some translucent and some opaque spalls. Spalls are predominantly grays, tans, whites and light brown, mixed.
This is the same product as the Mixed Texas Flint #1, minus the final cleaning step. You clean these yourself for more parctice. Cleaning produces flakes for pressure flaking and some waste. Lot contains pieces from 3 to 8 inches spalled in the quarry using steel spalling hammers.
Sold in 5 lb lots. The price works out to around $3.50 per pound--a great deal for high quality stone.
