Add one quart of this to one gallon of water. I dip sculptures that kids paint with tempera into this mix. I use glaze tongs to keep the shiny sparkly mix off of my hands. When the students' work is dry it is coated in a thin layer of shiny metallic plastic. The kids love this stuff. Order it from School Arts Specialty, formerly known as Sax Art Supply. It's about 18 bucks a quart.
