    KODALK Question.

    I know that Borax is disodium tetraborate (decahydrate) and that Kodalk is sodium metaborate.

    Is Kodalk the 4-mole or the 8-mole metaborate?

    This page claims Kodalk is the octahydrate. Check out this post, too.

    So the 8-mole then. Thank you for the links.

    How does one know if it is 4-mole or 8-mole? Looking at Photographer's Formulary, for example, they simply list the chem as sodium metaborate, no further information. More broadly, is there a qualitative difference between the two?

    Photo Formulary provides an MSDS on their product page, which states that their Sodium Metaborate product is also the 8-mole version.

    Thanks, Rudeofus -- I forgot about the MSDS.
