Gary Jackson: Fire When Ready Pottery
A Chicago potter’s somewhat slanted view of clay & play
Categories: process, studio

So tonight when I came back to my studio, I noticed some sort of random “fuzz” growing on my plaster bat. I use the bat to lay out my sloppy reclaimed clay. It sits on the bat for about a week before it is dried up enough to roll off and wedge up. I took my latest batch of reclaim clay off the bat about five days ago. I decided to leave my plaster bat sitting out so it could dry up a bit before laying out another batch of reclaimed clay slop. The bat is “elevated” on a couple commercial tiles so there is air circulation below it as well. I didn’t notice before… but I assume the fuzz has been “growing” since I took the clay off the plaster bat. I’ve seen little crystal-like build-up before, but NEVER this thick & furry!!!

Any thoughts of what’s going on here?
Should I be worried? Should I be concerned?
How do I fix the situation?… or is it too far gone? And time for a new plaster bat?!!!

Hi Gary,
It happened to me once. The plaster bat contained too much water so I removed those salt cristals with a dry stiff brush and let it dry outside for some time.
I love your blog! It is a routine to visit it every day!
Cheers from France!

We would get this same stuff in the community studio I used to go to in NH. It was around the plaster and I think this same time of year too. I was told it is a kind of mold, if so it’s the prettiest mold I’ve ever seen…

It is pretty amazing… a delicate crystal-like formation. Consensus says that it’s just a salt build-up. Nothing to worry about… just something to watch for with every batch of reclaim!!!
