Thank you all, maybe I need to refine what I am asking; we were talking about for example the next fiiring (glaze firing) when doing "ceramics". The thought being in ceramics, still making greenware, firing to cone 04 then glaze fire. The statement that was made was that a "glaze fire" for "ceramics" as I eluded to takes less time than "pottery" glaze firing.
Thank you for the input; I never really saw a different between making/mold pouring and associated process vs. Clay/Pottery hand building and now wheel works....
Input helps a lot!
