Re: Bottem of the Van Dyke Barrel

I did not find too much difference between year old VDB solution and totally fresh, exposed side by side. I did find a color difference, though, the new looked warmer and less grey.

BTW if doing VDB you have to buy the Weston paper...it is beautiful on it.

At first I thought it was my printer and inks. Then I thought it was a
change in my workflow somewhere. Maybe it was my coating method. No. It may
seem like a silly question but is it just normal that emulsions like VDB,
Cyanotype and others start to gain speed over time? I don't do a lot of VDB
but recently I was testing some of my remaining solution from a batch from
last year and it seems to be printing three or four times faster than it did
