Purpose of borax?

Postby ScottC » Sat Aug 12, 2017 3:03 pm

Does anyone add borax to their carrageenan? I recently read a book on marbling, and they suggest preparing the size with borax added. Is it used in this case to soften the water or balance the pH?

I read in an old book that it was used to prolong the life of carrageenan when they used the actual moss but there may be other reasons
