    Burton 95, H&W Control recipes?

    Anyone know where to look at recipes for Burton 95 and H&W Control developers?

    I spent some time on Google, and got no where (old posts telling one to use them or that they were no longer available).

    Thanks

    You can find the patents: one for H&W and another for what looks like a rip-off.

    I can't remember the magic words to get them to appear. Keep trying >> fine grain developer phenidone << and such for key words and something should come up.

    The way it was marketed, you'd think H&W Control developer would be something more exotic than that.

    I believe the Burton formula is also listed in "The Darkroom Cookbook" or "Film Dev Cookbook".

    Murray, did you also give the `Perfection XR-1´-formula a thought?

    The Holden and Weichert formula as published (Frugal Photographer) and allegedly used in the Bluefire developer is meant to be used quickly.
    The Carbonate is added to the developing agents and altho it looks like a bath 'A' and 'B' to mix as required nobody would put all that CO3 in with the phenidone and expect it to keep.
    I sugest putting all the sulfite in a bath 'A' and all the carbonate in a bath 'B' if you want it to last any sort of reasonable time and mix those as needed.

    A better solution :-) might be to disolve the phenidone and HQ as a concentrate in alcohol or glycol and have a premixed sulfite and carbonate solution ready to go - i.e. add enough of the concentrate to the volume needed for your paticular tank. I leave the math to you.
    That way it would last for a very long time.
    I have been using it for microfilms with success. I even add a little ascorbate to 'jolly along' the phenidone, but that's another story.
