All the mesc acetate I've seen is anything from light beige to dark brownish black, never seen anything yellow like that.

Maybe 69ron can shed some light on that wierd coloration.

Evaping vinegar without a ventilated room becomes very overpowering if you're evaping hundreds of mls.

You get used to it, but when you leave for a bit and come back it's like putting your head into a bag of salt and vinegar chips and inhaling deeply.
