Re: Silver Gelatin emulsion peeling from Cranes Diploma

["Christina Z. Anderson" <zphoto@montana.net>]

Josh,
Are you using a store bought LIQUID emulsion as in Silverprint or Liquid 
Light?  If so do NOT size or the layer will frill off in flakes, chunks, 
etc.  It needs to sink into the paper to an extent or it will lift.  I have 
never sized with liquid emulsion, but then again I have not used, say, a 
masa paper or whatnot.  But I found that even with a pretty absorbent paper 
like Arches I have had to REALLY work that emulsion in with the brush to 
have it  not lift and bubble off.
