Yikes! $75? I have a $20 set of Korean glass stones that I got at a Korean grocery store. No misshapen stones there, but there are only 160 stones per color instead of the usual 180/181 (This will almost never be a problem unless you want to try Ing counting). They're not pretty or anything, but they're solid and have a nice weight to them. I use them for studying at home. Shingwang is a nice company that makes cheap stones. Cho Namcheul, the father of Korean baduk was once on the corporate board there; perhaps that could be considered a celebrity endorsement. They have an English storefront on the web, although I have never tried using it.

EDIT: Perhaps your stones are nicer than mine. Mine are really basic (and somewhat small), even if they are cheap and reliable.

I have a set of size 38 glass stones on the way from Korea right now. I will look for deformed stones when they arrive and report on what I find.

I recently bought a set of Korean glass stones, and several of them are badly deformed in size and shape. I have seven set aside because they are unusable (they lean to one side as such an obscene angle they become an aesthetic detriment). Incidentally, they are all white stones thus far.

Is this kind of defection or poor manufacturing common in glass stones? Or did I buy a shitty set? Note I paid $75 for the stones alone.

Does anyone else have badly misshapen stones in their set?

Where did you buy them from?

Does anyone else have badly misshapen stones in their set? Also, do other materials (yunzi, shell&slate etc.) have the same issue, or is it just glass?

and yes, more likely with the white stones; the black glass stones seem to be more uniform.

Ok, that's not normal.

Please either send the whole set back or figure out how many stones are like that and send those stones back to me and we'll replace whatever you send back. We'll pay for postage and will show the defective the stones to 6 Brothers to see what they say.

If you could email me please we can work out the details.

Why is this, do you think? What is it about the white stones which makes them different to the black stones?

That's a good question, I've wondered about the same;
my guess is it has to do with the manufacturing process --
the white glass stones must go through a (slightly/vastly?) different process than the black ones?
I've never been to a glass stones factory, nor have I seen any videos, so I have no idea
how they make them. The ones shown in your photos are quite bad, and as David said,
not normal. For my 10mm Japanese glass stones set, I probably had about 1 or 2 white glass stones
with that kind of deformity. For my 8mm Korean glass stones, since they are much thinner,
even when a stone is "deformed", they physically don't have enough thickness to be
as lopsided as yours. But my guess is the Korean 8mm white stones would be in the range
of 5 - 10 with some unevenness.

PS. I like your cushion to contrast the white stones. I used a yellow-ish manila envelope
for my photos to show the manufacturers.

when simply contacting us directly would have seen the problem fixed quickly.
