Warning! Do not use a pump for acrylic liquid. It can cause contamination. Our Deep Ceramic Dappen Dishes are so easy to clean and use, you will never have contamination. These beautiful dishes weigh a 1/2 pound and have a cork bottom to avoid tipping. The well for your liquid was designed to keep down fumes for less odor and makes your acrylic balls perfect every time. The cork lid keeps your liquid from evaporating. You can use acetone to clean your dish and it will not affect the ceramic. These dishes make a beautiful addition to your work station! Our Deep Ceramic Dappen Dishes come in black and white. Tammy recommends you use the new Prizma white ceramic dish when using Prizma Powderz.
