I've lurked, I've learned ( well, at least I THOUGHT so), I experimented.
Yesterday was my first batch of tuffa. I wanted to make a big flat bowl container for sedum. Plastic container, real serious problems getting it to unmold. Do you guys still use a mold release with plactic? It wasn't a lip on the bottom in the sense of any kind of overhang, but there was a ridge and I think that interfered with getting it out. I broke the tuffa and the mold. Wondering - if I had waited longer (it had been 20 hrs) would I have been able to get it out at all? Would I still have broken it in the process? I cast on the outside but didn't use a measuring device and one side was significantly thicker than the other. The lopsidedness kind of appealed to me, but I think it wasn't going to be strong enough on the thin side. How thick do you make the walls of your planters?
I cast and carved a face - it's OK, nothing like some I've seen here but compared to my planter the face turned out fine,
I also did two spheres intending to carve either a word or a celtic knot on it. I think my mix was too dry. The outside of the sphere is very pitted - I don't think my carving is going to work. I set it aside to cure a little more, but not sure how long to wait before carving. I don't want it to crumble.
In any case, I was pleased that it didn't actually take that long to get set up and mix. I thought it was a much bigger time commitment and with 3 kids and a full time job my free time comes in very small increments.
