    Thank you,
    But what is the dilution for use, 1:X:100?

    Use it like the carbonate solution, but please do a test film before you do anything precious.

    I weigh out the Pot. Carbonate each time I make up some working solution and add it to the water first. After letting the bubbles that it releases disperse, I add solution A. Adding the borax to the water will raise the water temp about a degree C, so compensate accordingly.
