I am hopping somebody can help me out with a dilemma I have concerning a lava glaze I have got from ceamicsarts daily. There are two versions of this cone 6 lava glaze. One says 0 .34% silica carbide and the other says 34%. The current stoneware one I am using used 2%, so one seem a bit low and the other way to high. Thanks for any help avaibale. Lyn
