Re: SAME BRUSH; PT/PD & CYANO?

[Diana Bloomfield <dhbloomfield@bellsouth.net>]

Hey Loris,

Well, I meticulously cleaned my brush, too-- and the first time I did  
it, no problems-- after a very few repeated uses (both cyanotype and  
pt/pd with the same brush)-- even after cleaning very carefully-- I  
would get some slight discoloration, from the contamination.  Not all  
that visible, but I could see slight streaks-- very subtle-- but  
under the right light, I could definitely see it.

Brushes (even the famed magic brush) are probably the least expensive  
part of what we (I) do, so why not just buy another and avoid the  
potential contamination and headache.

I also agree with the poster who said they use a cheaper brush for  
the cyanotype coating.  I do as well.  In fact, I have a slew of  
cheap brushes that work perfectly fine for me.  I use the Richeson  
only for pt/pd, which really does seem to make a difference-- for  
that particular process.
