So several years ago I took a clay class where the instructor said that he often used acrylic paint with his younger students. Being a professional clay artist....I felt he gave me permission not to glaze everything! That was a weight off my shoulders. I have over 100 students in every grade level...20+ student in each class. It is so time consuming to glaze everything and fire it(and $$$). So...whatever you do...awesome...but I use acrylic paint for most of my clay projects. My 3rd graders did these fun masks..most with an animal influence. I'm praying my kiln holds out awhile longer...it is OLD...and I have no idea where the money would come from for a new one. I may try Donors Choice out.
