The consequence of removing "grog" from a clay body

[futurebird]

My clay is "yixing" and it comes to be bone dry. Then I crush it up in to chunks re constitute it and then add a little plum vinegar or beer and rest it. This is working OK.

 

The other day I added too much water and turned a batch to slip. I poured the slip in to low containers and let it evaporate.

 

 

Well, I inadvertently separated the clay! One of bodies is without any grit, and one has too much.

 

But could this be useful? I've been trying to get my teapots to have a higher shine and the grit free clay is VERY shiny-- and it has a lot of sparkling mica flakes too.

I think you made a crude terra sigillatta.

And you know how it works.
