I don’t use it on bisque

[Becki]

 

I don’t use it on bisque slumping molds because, frankly, regular kin wash lasts a very, very long time without reapplying. I do use MR-97 on frit casting molds because it gives a finer finish and doesn’t obscure the detail in the molds but once you use it on bisque you cannot go back to using regular kiln wash because the MR-97 seals the mold. I imagine the same is true for Slide.
