FeCl3 Mk 1!
Chris has cooked up our first batch of Ferric Chloride using the Wheal Jane acid mine drainage sample. I tested it down at John Howard’s print studio in Penryn last Thursday. It works…..just very slowly! John measured the density with a hydrometer and the baume was way too low, below 10 and we need it around 37-42…..but a few adjustments and we should soon have our own Ferric Chloride for etching.
