Starch paste preservative?
Today I tried an experiment making starch paste. Instead of dissolving cornstarch in water, I dissolved it in liquid laundry starch. This stuff has various chemicals added to prevent spoiling, so my thinking is maybe this would keep a batch useable longer than a week or so, like a typical batch of boiled starch paste might have.
Normally I just use Nori paste, which I love & works great, but it's a little pricey at $16 a tub.
Has anyone else done any experiments with adhesives using laundry starch? Surely I can't be the only person who has thought of this- but searching the bookbinding reddit doesn't reveal much.
Thanks in advance.
