> Are you using baking soda with the glut Chris?

Yet another nice thing about glut is that glut can harden gelatin at
acidic pH as well as alkaline pH. So baking soda would be unnecessary.
This is probably more useful for processes that don't work well in
alkaline environment, because the sizing can be made deliberately
acidic.
