wax resist final project

(not my vessel) But what i did was i made a coil pot in the shape of a bowl, then i drew a zig- zag pattern on the inside of the bowl with pencil after it became bone wear, then i painted the wax on and waited for it to dry, once dry i wiped the bowl with a damp sponge creating different depths of the clay. Where the wax was, was now a raised surface and the untouched clay was sunken in. Sadly after doing this step half of my bowl broke off when i was taking off the outside design because i didn't like it anymore. I kept the bottom half and glazed it a dark aqua color and it still needs to be fired.
