I have used some purchased square glass plates (with no foot ring) as hump molds; you just have to treat the surface and watch like a hawk for the right time to remove the slab from the mold.

I'd just scour the thrift or dollar stores for a cheap plate of the size you're after and either use it as a slump mould as it is (easy if it's wooden) or make your own mould from it by laying a thick (1/2") slab of clay in it, trimming, drying and bisque firing at a low temp (so it remains absorbent). Use this as a hump mould. Slump/ hump all depends on the inner / outer profile of the original. Good luck!

Not sure where you are located and what size you are looking for, but here is a US based website which has both slump and hump molds in plater. I have not used this vendor so can't speak to their service.

Also, you could potentially use a square bisque plate for a slump mold.  There are several square ones if you scroll down this page.  I've been pleased with Clay King as they ship fast and have good prices.

Or you can purchase a square platter, no foot ring, invert it onto a slab of clay, press slightly into clay, coat the platter liberally with vaseline and pour plaster over it, all boxed in of course :D  Plaster set, remove the removable and you have a mold.

I use Chinet paper paper plates. They have dinner as well as salad size. Also pretty cheap as far as a mold goes and if it's just for a gift you can toss it when you are done. I have found though with some care you can use them repeatedly before they lose their integrity.

Try a square piece of plywood on larger piece of plywood 3/8"-3/4" bevel the edges on a table saw, or add pieces of house molding to the edges for a sculptural edge. Get even more involved by using dremel, or carving tools to carve a design into the molding. Press slabs on, and away you go!

I think if you were to take a picture frame, remove the cardboard backing

and replaced it with 3\8 plywood this might work. Plywood would strengthen

the frame since ordinary frames are flimsy compared to the boards used by

the lapellart video. I ll try it today to see how it works.

See ya later

Face down, and face up are considerations. When place the slab on a hump mold, the inside surface is more defined than the surface you get from a slump mold. So in the long run it depends on how detailed you want your top surface to be.
