I just want to make sure it would be safe to introduce brass to the 
mixture without any dangerous changes in composition.

I will also be doing small etchings also, but if it works out OK, I 
may end up selling some of my etchings, and therefore would like 
to "renew" the mixture using the bubbler method.

Plus, I am used to the bubbler in the etchant to help etching 
speeds, along with an aquairum heater, from other etching 
techniques.  

Also, i wanted to make sure it would be safe to store this mixture 
in a Rubbermaid container, or if the mixture would create enough 
gasses to blow the lid off, if brass is introduced.  A previous post 
mentioned that brass etched in this mixture may create too much 
bubbling.
