It's a bit like Scotch, the effect seemes to vary depending how much water
one puts in it.
Now I have replaced my Baume hydrometer for my ferric chloride for gravure, I
will use it to measure
the viscocity of my Bakerex. I have tended to work at 17 degrees Baume in the
past. I intend to 'go into production' with the leasst expensive poly vinyl
alcohol which gives the best results..
