I would like to discuss the creation of one or more tags for amorphous solids, glasses and quasicrystals.
There are many question on the site which address specifically glasses and the glass transition, for example this one and this one and this one.
Others are about amorphous solids in general, like this one, this one and this one.
Finally, other questions are about quasicrystals, like this one and this one.
We have a tag for spin glasses, but not a tag for glasses. I find this to be pretty absurd.
I recently proposed the tag amorphous-solids, but I'm wondering wether it could be useful to create the tag glasses (or glass) since someone asking a question about glasses will probably try to type "glass" instead of "amorphous".
Also, it could be useful to create a quasicrystals tag.
Update
Since the response has been mainly positive (or no one seriously objected, anyway...) I will create the glass tag. As for the quasicrystals tag, I still haven't decided what to do.
go
on the quasicrystals as well, particularly if you can unify the existing questions under it. $\endgroup$ – Emilio Pisanty Nov 23 '16 at 11:10
