Don't tell me book authors are just making up/and or redefining words......
Come on now, poetic license can only go so far.
But I guess if you simply MUST "felt", just don't breath in mercury vapors for too long and end up "As mad as a hatter", felt on!

P.S.
As long as we're at it, I have recently experienced some "terflecky" left over in a blender I didn't clean out real well. The plastic cleaned up well, but the blades are just a mess. Does anyone have any suggestions for cleaning terflecky off stainless steel blender blades?
Hi Paul, I've got a Fara Shimbo book that talks about it. It seems to refer to a fault and I'm guessing it's bits that stick up, but I'm not sure. I googled it as well, so I'm hoping someone here can help me!
I was going to make an inane comment on inventing words, but managed to suppress it. You should go to the book and just copy how the word is used, now I'm curious.

from the book, Crystalline Glazes: Understanding the Process…by Fara Shimbo (2003),
page 17...
"Sometimes grog or sand intereferes with crystal growth, resulting in "felting" or the tendency of crystals to grow perpendicular to the surface of a pot, resulting in an extremely rough surface. ......"
page 31...
".... The trick to growing beautiful crystals is stopping the heating of the glaze at the point where seeds are plentiful enough to start the desired amount of well-placed crystals, but not so plentiful that there are too many crystals and felting occurs. ....."
page 42...
"Spodumene alone is not necessarily a good addition to a glaze because it does promote felting when used with cobalt and iron. ...."
page 66..
"In addition, cobalt glazes seem to be more prone than others to felting or over-crystallization."
page 113...
""Felting" (over-crystallization) can happen under several circumstances, and seems to effect some colors far more than it effects others."

It has been a really long time since I have gotten this but here is an old picture. I do not have any better pictures and I do not have any pieces like this to take pics of.

"Porcelains (or stonewares) with grog or sand will only cause you heartache. The grog particles will act as nucleation sites (or starting points) for the crystals, and you can end up with far too many of them. Sometimes grog or sand intereferes with crystal growth, resulting in "felting" or the tendency of crystals to grow perpendicular to the surface of a pot, resulting in an extremely rough surface. ......"

Is it wrong that I posted this? Like straight from the book... If so I'll take it down. I didn't ask for permission or anything... I don't know how all that stuff works.

Well, that was almost too easy! I'm not sure I like the word, though, because it seems to put too many properties into one word. It can be underfired, too thin, it may be good or bad, depending on other things going on in the glaze (usually bad, though, I think). Wow, there should be a word for the preceding...oh, wait, there already IS, "b###sh##"!

Here's one of my most extreme examples, you can see empty space underneath the crystals at the bottom of this bowl. It feels a bit sharp to be termed felting though.
I believe this happens more so on flat surfaces than vertical surfaces and it is not the result of a thin area but rather a thicker area and when the glaze has either too much zinc, not enough melt, or both.
