iIhave had the students use marbles for the bottom of a clay piece but they
also put in some clear tranparent glaze with the marbles ...the marbles once
fired...they cracked but everything stayed in place
Also...if you have some old stainless steel mixing bowls and you coat them
with a kiln wash....giving several coatings and "preheat the stainless steel
bowl"...you can drape a piece of glass over it to create a bowl....better yet
get some glass that is COE compatible and students can create their own
design using stringers, noodles, frit, confetti and pieces of glass....they
love it...i do this with middle school students and is very successful.
