Beth I haven't checked to see if there are other answers to this - how about a non oil based gelling agent? You'd have to keep it in the fridge, but starch based like they thicken foodstuffs with? You don't have to heat anything too much but its pretty instant, or agar gar, something like that?
Jane ----- From: Bethany Methven Could anyone give me some ideas with making a colloidal silver gel? Thanks - Beth
