    Chemistry Question: Sodium Sulfite & Sodium Carbonate

    I have two quart amber glass jars in which I stored my sodium sulfite and sodium carbonate stock solutions for making ABC pyro. I haven't used ABC in about 6 years and never emptied the jars. The solution in one jar is clear. Is that the carbonate? The solution in the other jar is black as pitch. That's the sulfite, right?

    I'm not entirely sure what you have in solution but, assuming that these are simple water solutions...neither one should be black.

    I have had these for years and years. I have never seen either turn black.

    I wonder if they reacted to something like a jar lid or other contaminate.

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Maybe it was the Solution A jar that I didn't empty. So now the question is: do you guys know of a quick and easy way to tell if the clear liquid is sulfite or carbonate?

    test the clear solution which appears to be functional.

    develop some cachetol with it.

    if it is carbonate, you should get an image. if it is sulfite, you won't.

    Would Pyrocat HD Solution A work as 'catechol'?

    all this time, I can't help thinking...sulfite and carbonate are both cheap and readily available (here in the US)....why not just dump out what you have and mix up some fresh?

    As cheap as both are, just dump 'em!

    Dump the contents are thoroughly wash both containers.
