XTOL mixing, part A cakedgreenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
opened my first packet of XTOL, and was a little surprised to see that part A was not a pure powder, but clumped together. dissolved okay, and part B was as expected. has my curiosity however, as to if this is normal. the package appeared to be sealed from air. thank you.

Yes, it is normal. Part A has always been like that everytime I have purchased Xtol. It readily dissolves in water, so you can tear open the package and dip it in the solution to make sure you get all of the "powder".

I have heard that a batch or two of Xtol didn't have a good seal on part A. I have only had one packet which had a "caked" part A, and all the rest have been a normal, dry powder. Try it on a test roll first before using it on your normal work, as I have heard bad results when the caked part A has been used.
