Bottem of the Van Dyke Barrel

[Michael Koch-Schulte <mkochsch@shaw.ca>]

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
initially.
