Gerard,
I'm not sure if you wanted to know if you can reuse the solutions or
how long they last, so I will try to answer both.
You cannot reuse the solutions once they have been heated and the
developer should be mixed together immediatly before use, then
discarded.
The solutions should be kept in the refrigerator, even the gelatin(just
heat in the microwave to melt before use). The solutions should be fine
for 3-4 months.

I hope this answers your questions.
Kathy
