Re: [GBW] washing family documents

Wow! Hmmm......

Well, I know Talas have never claimed to be expert conservators, or 
bookbinders, or anything other than sellers of supplies for these 
industries, but to be honest I am pretty surprised that not only do they 
still carry this stuff, they also recommend it to people like me!

Frank, thank you for your advice on this one.  I'll be returning the 
Chloromine T unopened.

Best wishes,

Tony Farthing

Unbelievable.    Chloramine T has not been used in the conservation of
Paper for over 30 years.
In the 70s conservation scientists found out that it was one of the most
insidious bleaches that had been used on paper. It is practically
impossible to remove from the paper once applied and over time will
destroy the paper.

Please stop and refrain from bleaching paper this way.  For
nonprofessionals the only "safe" method is Light bleaching, where one
places the paper to be bleached in a tray with 1-2 inches of pure water
(not contaminated by copper or galvanized iron pipes)  and expose it to
intense sunlight or a bank of cool white UV shielded florescence.
Depending on the stain it may take several hours or more.  Wash the
paper again after light bleaching to further remove degradation products
released during the bleaching process.

One of the most difficult objects I have been faced to treat are papers
that were "bleached" in the past and were done improperly and without
careful subsequent treatments.  They are always brown (in a unnatural
way and tone) and very brittle.

I use 2 teaspoons of Chloramine T per one cup water. Use warm water,
stir in the Chloramine T. Get your document good and soaked in the
wash tray, then pour off as much of the solution as you can. Let it
air dry. If it is still stained, repeat the process. When it is
sufficiently cleaned, soak the document in warm water for 10 minutes
or so. Pour off and let air dry.

Good luck!

Steve
