Yea they broke. I was a bit stupid and used a cylindrical handle with no curve on the end so I wasn't surprised. Still, it had snapped in two before I noticed

 

 

Do you thing that this was enough to cause your mould to snap when trying to separate them?

 

BTW twisting a coin (halfpenny bit) or a teaspoon to make a rounded notch works well and avoids undercuts.

Looking at the photo I wonder if your alignment notches were OK. It looks like they may

have broken when the mould pieces were pulled apart.  Is this the case?

The bag should have an identification number on it (perhaps a P followed by 4 digits)

which might help identify quite what you have got.

 

Although Potterycrafts sell quite a few moist porcelain, they don't sell many powdered ones.

Indeed the only powdered porcelain one in their current calalogue looks like the one I have used in the past,

which already contains defloculant.
