Hello. I tried to make a wrap vase and after I stood it up it basically collapsed. Should I have left it on the form until the clay was harder before standing it up?Im thinking it was soft so it slumped down.

Your clay might have been too soft in terms of wetness, so it was just not set up enough before you took it off the form. If pressed for time and you need to take a form out of a mold sooner rather than later, you can point a small fan at it, be sure to rotate often so your edges don't crack from drying too fast. If your environment is very humid or just not helping it dry, you can put it in the oven ON VERY LOW TEMPERATURE, 150 degrees MAXIMUM should be fine and not explode your mold if its plaster or glass. If your working with a plastic mold, try surrou d it with bisqueware or boneware as it sets up, those will draw out the moisture and quickly. Drying evenly is whats important. If you form is cracking as it drys regardless of how you dry it, your clay might not be compressed well enough, which you can fix by wedging your clay more thoroughly, or going over the clay slab, before you put it on a form, with a metal or rubber rib. Hope this helps!
