Re: Do dichromates change with age?

Good to know. I bought a gum 'kit' and other small bottles of ammonium and potassium dichromate and related mats to do gum printing from B&S several years ago, then found other pursuits I was interested in -- and never even opened the stuff. Not sure what all is on the shelf related to gum.

If anyone wants it, please contact me off list and I'll ship it to you. Winner take all.

to see if there was a speed change when I got new. No detectable
change at all.
