I finally got back to tinkering with carbon printing this week, and
discovered that my 3% solution of potassium dichromate had coated the
bottle with a brownish black sediment. Is this normal? I strained the
solution through a coffee filter, and scrubbed the inside of the bottle to
remove as much of the sludge as possible. A couple of sample prints made
using the solution seemed to turn out OK, but I'm wondering how long I can
expect this solution to last?
