RE: gum dot test - Crawford

Dear John, your question about the dot tests excites me strangely.
Should you do the test and actually manage to get any useful information
out of it, can I marry you??? I will be waiting with bated breath to see
if you reply......

Subject: gum dot test - Crawford

Hello list
 
I'm about to do the dot test en masse as on page 211 in Keepers of the
Light. Watercolour pigment is given in length of 3.8cm or 1 1/2" but
there is no mention of tube weight. Pigments I want too test range from
5ml (0.17 US fl oz) to 37ml (1.25 US fl oz) and the exit holes of the
tubes vary in diameter, so a 3.8cm length doesn't mean much. Can anyone
enlighten me on either the tube weight Crawford used or give me a sample
weight as a starting point.
 
Many thanks
 
John.
