Fellow Apuggers, When I mix up D76 from scratch, I usually make just one litre of stock solution. I used to weigh out several batches of each of the chemicals (and bag them up) so I could easily make up another batch when needed without farting about weighing all the ingredients again. The trouble with this, and admittedly it's only a minor problem, is that it becomes quite heavy on the little plastic bags I use for storing the weighed out ingredients. Like the Ilford or Kodak products, can I package any of the raw chemicals together e.g. the hydroquinone with the borax or, perhaps more to the point, which chemicals should I avoid storing together?
