i agree the clay is dry. I also agree this could be dangerous. In the UK if I had employees working this way, i would be fearful for their health and suing me for not providing protective masks. I do fear that there must be fine particals of dust in this process. When wet turning the clay is too damp to separate and lift to get into the lungs.
First of all, these pots are bone dry. If there was any moisture the clay would be sticking together when it was trimmed. Secondly, it isnt dangerous- risky, maybe, but he obviously knows what he's doing well enough to have the wheel spinning full speed and also the amounts he takes off in just a moment says a lot! You can tell he is experienced. It's nice to see how this works, he probably doesnt have to worry about them drying now, he can trim them no matter what.
Hi Savannah! LOL I can't remember what I was thinking 6 months ago, but it just doesn't appear to be bone dry. Looking back at older comments, I see others are agreeing with me. The shavings even *sound* heavier than bone-dry shavings would. Those are some sharp-ass blades. WANT!!!
They all trim the porcelain at this stage in Jingdezhen and they probably have been for couple of thousand years. Silicosis maybe but then why would they all trim like this?
It seems that clay has different qualities to those most of us are used to, to trim like that BUT where's his mask?? Everytime he blows the debris away some dust is going into his lungs - can't look!!
The piece is very dry--it does not peel off in ribbons--but there still must be a small amount of moisture in the clay. If it were absolutely bone dry (i.e. ready to be fired), it would not trim like that no matter how sharp the tool; instead, it would come off like a powder.
@rwheeler67 yes the plaster bat that he is trimming on will make enough grip to not let them slide but he has to keep downward pressure to keep them from flying off the wheel
i would never do it that dry ....with or without a mask

@ThatLynnGirl You will find that the clay is still quite damp, any drier and it would not turn as easily as it is doing.
When clay is dry and sanded this is dangerous.

is there any reason those cups dont slide off and break? is it the hole in the middle of the bat?
rwheeler67 2 years ago
he's not putting any force on the sides, just straight down.
tmachris91 2 years ago
then wat is the hole for?
rwheeler67 2 years ago
the hole is to trim the top of the the cup.
if you look carefully, when he tap centers the rim of the cup is bigger then the hole
tmachris91 2 years ago
@rwheeler67 its for reference on the center allot of the production places have that sort of thing to mark center and make it less work to tap center
