Subject: Old Wei T'o
Solutions of Wei T'o which are 8-10 years old are not likely to be useful. You might contact Dick Smith at P.O. Drawer 40, Matteson, IL 60443, (312) 747-6660 to confirm this. I recall a discussion I had with him some years ago during which he mentioned that some formulations of Wei T'o had a shelf life of approx. 6 months. Jack C. Thompson Thompson Conservation Lab.
