This is my first post here, having been a lurking reader for a while.
I would like to suspend some coarse particulates in a porcelain slip. I am intrigued by the coarse feldspar inclusions in some Japanese wood fired pottery. I have tried adding coarse inclusions in a porcelain body, which fired well but the large chunks got in the way of my preferred style of handbuilding and surforming the surface.
I now want to try to add these particulates in a porcelain slip that I can apply to my pots by dipping.
Does anyone have any tricks on how to suspend larger particulates in a clay slip, eg grog or coarse inclusions? Do grogged slips exist?
I was thinking that perhaps adding bentonite could help due to its thixotropy, but I am not sure.
Any help from this very helpful forum in my self-learning endeavors would be much appreciated
