    I’m interested in this terra sig for raku… how do you use it? Do you just apply it like regular terra sig, on bone dry greenware, bisque and then raku? ??????? Or is it put on bisque ware?

  • Harry K.

    What is “XX”? What “saggar clay” do you use?

  • Should be 15 lbs. clay.
    Very good recipe, if you don’t use 115 lbs. clay.

  • Mona T.

    This recipe is definitely flawed! 115 pounds of clay mixed into 3.5 gal. of water does not read correctly. Please review this for typos. MT
