Oh YES!!!....drove my instructors, kiln technicians and fellow students mad at college firing all sorts of things in the kilns to 'see what happens'.......
......steel at 1280C liquifies and burns through the kiln shelves destroying everything in its path
......hay/papers/woods/leaves/seaweeds etc smoke out the kiln sheds and encourage the college neighbours to phone the fire brigade
......tin/chrome formulas made whole kiln loads turn out puce-y red affecting everyone elses work as well....not popular
......the leftover slops glaze that ran and glued everyone's work to the kiln shelf
......the crackle glaze applied over a glassy parian clay body that ripped all the work apart in cooling
....etc, etc, etc.....I spent my whole undergrad experimenting rather than producing a coherent body of work, I wanted to know what 'everything' did knowing I would not have such a fully resourced ceramics studio and college library again when I graduated so wanted to learn as much as possible,..... still experiment but far more carefully now!
