We have some glazes in our program that should run (see pictograms in the catalogue), so please only glaze the lower area of ​​your object very thinly. But if other glazes run off, it could be because the application was too thick or because the temperature was too high. You may want to check the oven temperature actually reached using Seger cones (or Orton cones). We recommend protecting the oven plates with a release agent (e.g. BOTZ release agent item no. 90108).
