    Looking for an inexpensive source for the above.
    Freestyle doesn't list anything.

    Thanks, I saw that at B+H, but the cost is over $30 with shipping.
    I learned that Freestyle has it listed under another name: Moersch Restrainer Neutral, less expensive than B+H.

    I believe this is just Benzotriazole (BZT). Buy some bulk from the formulary and mix it up.

    Benzotriazole dissolves sparingly in water, but better in an alkaline solution. I read somewhere that Orthazite was just benzotriazole in a mildly alkaline solution which I think was just sodium sulphite. The sodium sulphite would have a negligible effect on any developer.

    How much do you want Karl, I could put some Benzotriazole (dry) in a film cannister, postage would be about $3 to Canada/US.

    I, like Ian, also have a lifetime plus supply of BZT needles ( 96 or so of original 100g on hand presently I think). If I am more local I would be pleased to mail you a few grams. PM me if you are interested.

    I think you're a lot more local :D A little Benzotriazole goes a very long way.

    I have a pound of it and use it at 1% solution. I'm making provisions to pass it in my will :D..EC

    I use benzotriazole all the time. It doesn't take much. Maybe a dollar a year for a benz junkie like me.

    BZT dissolves easily in alcohol. I mix a 1% solution dissolving the chemical in 200ml rubbing alcohol, add water to make a liter. Easy. Quick.

    Once I used a liter of alcohol to dissolve it, not knowing any better. Almost fumed me out of the darkroom putting a mere ounce in a tray of developer!
