My partner and I want to slip cast cups, I have a bit of an idea when it comes to ceramics (thanks mum) but have some questions :)
We have found a clay that already has a speckle in it - can we use it to make slip for casting?
If the clay cannot be made into slip - is there something we could add to plain slip to make a speckled look (that's food safe)?
Can we add pigment to clay/slip that already has a speckle? Would this interfere with the chemistry?
I know the other option is to use glaze to achieve a speckled look but we would prefer that it came from
