I'm a little stuck... Click here to teach me more about this clue!

'chemical weapon' is the definition.
(I know that tear gas is a type of chemical weapon)

'from the air glass oddly is a' is the wordplay.
I cannot quite see how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'air' could be 'gas' (I've seen this in other clues) and 'gas' is present in the answer.
'a' is present in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for tear gas that I've seen before include "Police use it for riot control, hurts the eyes" , "Discharge sprayed by riot police" , "Crowd disperser" , "Riot control weapon" , "Lacrimator" .)

I've seen this clue in The Guardian.
