In Topic: Removing Greenware From Ceramic Mold Questions

I've made vases about 18" and 14" tall, not cone shaped though.  

Sometimes as you pour the excess slip out it will 'glug' causing the soft slip to pull away from inside the mold.  Be very careful and slow as you do the pouring.  

Experience will show you how long to let the slip stay in the mold before you decant it.  I found that the drier my mold, the less time I had to let it set up.  

Perhaps one of your mold pieces has something on it that resists water, that can slow the movement of moisture into the plaster and cause thin/weak spots.

I have been able to rub the pinholes out at greenware.  Depending on what your mold looks like will depend on if your piece will crack.  How many pieces is your mold?  Is it mostly enclosed or have a large open area?  I have had some luck on a 3 piece mold taking one side and the bottom off, leaving the other side horizontal with the piece still inside of it. Then putting the first side back on and flipping it and exposing the wetter side to air.  

You can reclaim the botched and dried pieces - takes time, but it can be done.

It takes practice and time to make good slipware.  Good luck

Sorry for your loss.  

For human urns I've been told to figure 1 cubic inch per pound.  For a 200 lb person + or - that would be an inside measurement of 6 x 6 x 6.  I've figured that to be a bit less than a gallon size.  For Thanatos at 10 lbs that would be less than 3 x 3 x 1.5, maybe a cup, cup and a half.  You do beautiful work.  I'm sure Thanatos would love being always near you as you play in clay.

I use stretcher bars from the painting section, they come in all sizes.  I suspend the clay on a piece of cloth over the bars after I cut the clay to size.
