7267RE: Tragacanth size paint
- Nov 25, 2013
The ox gall I have is from Talas and I had a bit of a class with a marbler awhile ago and I think he said tragacanth requires either 4 or 8 (I don't remember which) times more gall in the paint in order for the paint to float. However, I've tested drop by drop untill there was about as much gall as actual paint mixed together and it still wouldn't float so I think maybe it would be better to try with pigments(once I know a bit more) because of the reliability. Also totally forgot about my name showing because I thought it would just show on my email haha.

Dear "ui9ojiopk" (You didn't give your name),
What kind of gall are you using? Is it what Windsor & Newton sells? If so, don't waste your time. If you're in the US, get some from a marbling supplier like Diane Mauer, Iris Nevins, Garrett Dixon, Colophon Book Arts Supply, or Talas. What they sell is a lot more concentrated and typically preserved in alcohol. In Turkey, the gall that they use is prepared in manner similar to how Turkish coffee is made, which is more concentrated. In my experience, marbling on tragacanth requires a bit more surfactant than when marbling on carrageenan size.
As far as making your own paints from pigments, I wouldn't describe it as 'easier' so much as more 'reliable'.
Best of luck,

It floats but it kind of spreads into a vein like look. They are winsor and newton designers gouache paints and i first add enough water to make it the consistency of skim milk. I think i have to add a binder like gum arabic to the paint to fix it but I'm not sure. I would also like to know if maybe mixing paint right from pigments would be easier than using a brand of watercolor paint in the sense that you would know exactly what the paint contains and would be able to fix it easier.
