Use hide glue and titanium oxide (snow white) mixed 5:1.  After the batch
has gelled, cut it into cubes and store it in the fridge or freezer
(haven't tried that yet).  This way when you need a little, get a cube
and pop it in the microwave for 12 sec or so.   Instant hot glue.

I do the same with plain hide glue too.
