What is 'slumping'?

I hear it talked about, but never defined.

I get the gut feeling it's laying a piece of glass over a mould, then
heating in a kiln till the glass take the form of the mould. Close? Am I
even spelling mould right? :-)

yes.

in the US, it would be mold. in the UK, it would be mould.

see http://warmglass.com for a tutorial on this subject.

The simple answer is that it is taking glass to the point that it changes
shape but does not change detail of form.
[The simpler answer is that you are right.]
Fusing is taking bit or shapes of glass and heating them until they more or
less melt together.
Sagging doesn't go this far. The glass used in sagging may have been fused
previously to form a color pattern (like make a checker board) or design
(make a picture on a solid background.)
It is possible to fuse into a mold, doing both steps at once with less
control. (as I do)
Sagging may be into a mold, over a form (usually stainless steel) or through
rings or holes (drop out).

Once again, Empty Bowls for the North Texas food banks will collect money
in February by charging for donated food and bowls at artsy events in Dallas
& Fort Worth. Check out your area if not near here, Empty Bowls was
originally and still is mostly a pottery project. All it takes is a box
stuffed with newspaper and one bowl a week to collect a dozen by then.
$23,000 raised last year.

And if it grows, it's moldy or mouldy...and if it spatters on the wall it's
spam.
