A larger attempt...

Trying the previous example but slightly bigger and not in a ball (like a did before) but concave...so when the plaster is thrown in and wiped over I'll have a half hole-y half solid blob-ish shape. Hopefully.

Sadly the damn thing broke when getting it out of the mold. Someone in my class suggested I add water based PVA to strengthen it, keeping in mind it would take a little longer to dry, and maybe some rock dust. Well I only had the PVA, added that and it turned the plaster more brittle. The bloody stuff crumbled!

But my idea worked, this is what I was after. I'm loving it!

Plaster casts...kind of

This is my first attempt at pushing a cardboard tube into clay, TRYING to get that outer texture on the cardboard rings KEPT on the outside, even in a plaster replication.

On one side, is a flattened surface where I had poured the plaster into the mold and wiped it away to create the holes. I want to keep this flattened side on the inside and the nice textured side on the outside. Proving difficult.
