Was Re: question on sizing, now fish eyes
Hi Kerik (and Keith), Your email made me realize that I might have misinterpreted DJ's original post and Keith's below, so a need to clarify: I'm talking fisheyes in a gum/pigment mix, not the gelatin sizing. I think that DJ was having fisheyes in his gum coating on top of a gelatin size hardened with glyoxal. But you and Keith are talking additions to sizing (or are you, Kerik?) to make it smoother, less bubbly, etc.? I do use your method of Everclear in my gelatin, about 20ml per liter, Kerik. So I guess my question is are you two adding these things to the gelatin sizing only or the gum coating as well? The reason I ask is this: as is always the case with gum, troubleshooting explanations will contradict. I have a host of reasons for fisheyes. Insufficient gum in relation to pigment, coating mix too "limpid" or as we say thin, yet another says to increase the sensitizer in the mix because it is too much sizing for amount of gum used, air bells, medium in some watercolors, and those "globules" that are visible under the microscope one author says. If Everclear or Defoamer helps with fisheyes that might say something different even than this. Chris __________________ Christina Z.

Judy turned me on to this magic elixir many years ago and it seems to make life easier.
