Re: separation of substances

hello, after one year of testing (i did a LOT of testing) i found out that the best solvent was ethanol at 96%, but still some of the polyvinyl alcohol got mixed with the dye and when i heated it burned into a gelatinous substance, of six attempts using the ethanol i only got it completely right once, completely separating the dye and not getting it burned; the other five however got transformed into the gelatin i wrote about.
I read somewhere that some persons used borax in the polyvinil alcohol containing solution to have it completely removed.
any ideas?
