Of course, still, there's the problem of gum not being a defined compound
(it can change depending on source and year of harvest). Therefore I'm
interested in synthetic alternative such as PVA. I haven't find a good
source of suitable PVA, plus, I'm not completely sure which kind of PVA is
most suitable for our purposes. As soon as I figure these out (source and
type), I'll leave gum aside and use PVA as the colloid. (My current
understanding is that something like 85% hydrolized, with a molecular mass
around 10 - 12.000 should do well... Any thoughts?)
