RE: Do dichromates change with age?


If it's not too late I'll take the gum kit off your hands.

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.
