In my research, I used ultra-low-viscosity HPMC at 2.3 mPa·s, which can be misted at relatively higher concentrations while still producing a very fine, low-impact aerosol: https://www.mdpi.com/2071-1050/15/20/14699 <https://www.mdpi.com/2071-1050/15/20/14699> Because of its low molecular weight and low viscosity, ULV material may also diffuse better into fragile or porous structures and could therefore help with consolidation where penetration is needed. For comparison, A4C is around 400 mPa·s, so the difference in viscosity is substantial. Methocel grades around 4 mPa·s also exist and may be relevant for this type of approach. I have both ULV MC and ULV HPMC in my lab, and I would be happy to send you a small sample if you are interested in testing it on mock-ups.

During my practical work, I have come across several silver gelatin prints with very fragile, powdery emulsions. While researching appropriate treatments, I found that Klucel G (2–5% in ethanol) can be used as a consolidant. However, I was wondering whether anyone has encountered a similar issue and could share their experience or preferred treatment approach. Thank you very much in advance for your time.
