Re: Sugar and or Glycerin

I have to admit to only trying to make tissues a few times. In the
Colorado highlands water is very scarce so the tissue, if it is very
large, is almost impossible when it dries. I need more time to get back to
Carbon.

This email keyed my interest again about just what we can use to keep the
tissue flexible. I think there has been many tries to accomplish this but
I just did a search and discovered a biological application that needs
flexibility and a substance that might be a good replacement for sugar,
although it looks to be a saccharide, a form of sugar. Here is what I ran
across:

 glycosaminoglycan gel

powerfully water absorbing gel called a glycosaminoglycan, a
polysaccharide or sugar complex

A key ingredient of the gel is hyaluronic acid, the most hydroscopic
material known in nature…

Sounds exactly what we need. I doubt it will harden the gelatin prior to
development.

Now to find a commercial supplier vs a human injectable level of product
for experimentation.
