I heard something yesterday that just reached right into my skull and swiveled my brain.
I was talking to my local clay supplier and at the same time fitting plugs into the bottoms of a salt and pepper set when she said, "The holes don't shrink, you know, between when you make the piece and when you finish firing it."
"Whaaaaaa?" Brain said.
"Whaaaaa?" Mouth said.
"Yes. The hole doesn't get smaller; the clay shrinks, but the hole stays the same."
"Uaaaaggggg, Whaaaa?" Brain said.
Jeanette said to Brain,
"Call up that mental image of the hole in the bottom of the salt shaker.
Run the footage of the hole in bisque firing.
See the clay shrinking.
See the hole stay the same.
Run glaze firing footage.
Ask yourself, How can the hole shrink with glaze all over it?
Huh...... She must be right."
By golly, she must be right. I can't visualize the clay gathering up in the firing and shrinking the hole. I can visualize the clay platelets solidifying and the spaces between them changing and getting compressed or with glaze flowing over them, but I can't see them binding together to draw a hole up smaller.
Message to Brain:
Keep track of holes in things and measure after each firing to see if this is true.
File under Puzzle Section in Drawer Re: Screw-on lids and other mysteries. Could have a bearing on figuring out how to make these.
Que music from "Brazil".
Note: If I ever got locked up in stir, I could easily fill my time thinking about stuff like this.
