I am getting into a creative groove and was excited to have a customer/student ask if they could make a dimensional porcelain (or other ceramic clay) heart wall hanging. She showed me photos of what she had seen another artist do.
Well, not wanting to copy, and not having the photo in front of me (just my memory of what was in it), I proceeded to try to fabricate a hump mold to create them on top of... that failed me... so, instead I just used a curved piece of lightweight chip board, like gift boxes are made from. In fact, I used some shirt boxes I purchased at the dollar store.
This was my prototype. It is still un-fired in this photo. It is difficult to see that it is a convex curve. The ones in class are much more pronounced.
The glazes I ordered on the 4th didn't arrive until the Monday after the Saturday class... frustrating! But, they couldn't have used them that day anyway.
I have made multiple test tiles to sample a variety of glazes and their compatibility with one another. When those are done, the ladies can glaze!
