Today I will share with you my experiment to determine how waterproof is lumina clay.
I always do a waterproof test out all the clays I use before I make jewelry. I want to make sure all my products are made out of materials that will not have a reaction that will ruin my customers clothes. Of course there are always unforseen circumstances but for 99% of the normal occurances I like to be sure everything will be okay with my creations.
So since I used ink, acrylic paint and oil paint to tint lumina I needed to make sure these items are really waterproof and the pigments wont leak out of the clay if they get wet. So I decided to do a 5 day test to see what would happen.
I took several pieces of tinted clay and I put them in a ziplock bag filled with water. Below is a picture of the pieces of clay before I put them in water
