Figure F4. A. Smear slide of glass residue remaining after a 2-M Na2CO3 digestion of site survey Sample EW9709-7PC: 122-124 cm (#0945, slide 10). B. Smear slide of residue remaining after KOH digestion of site survey Sample EW9709-7PC: 122-124 cm. Note the lower abundance of glass remaining compared to amount in part A (#0947, slide 11).
