    What volume of ready to coat emulsion does one mole silver nitrate make, when made according your procedure?
    ----------------------------------------------------------------------
    My largest batch, so far, has been 0.4m. That made slightly over 2,400grams,prior to filtration.
    ------------------------------------------------------------------------

    You said the Glyoxal aids drying...how long does it take to dry without the glyoxal?
    -----------------------------------------------------
    Depending on humidity and ambient temperature, overnight(around 8 hours).In very humid weather, longer.
    --------------------------------------------------------------

    Wouldn't it be possible for your seller to just purchase the gel substitute and
    resell it, rather than make it themselves?
    --------------------------------------------------------------------
    Nobody makes it,except me. I have done patent searches and searched the market. The CA I have with that company is primerely for the gelatin substitute itself. That is where the time and effort is. The emulsion recipe is very simple.
    I will push as hard as I can, without generating hostility.
    So far, they have made one batch of the gelatin substitute. They sent the whole batch to me for evaluation. There batch was up to par.

    Sean and Tim,
    I just do not know. Spraying these emulsions could be very risky, from a toxin standpoint. A good fume hood would be the least you should have. Just spraying gelatin is one thing. Spraying silver nitrate would take a lot of planning for precautions.
    I doubt that inkjet inks are very toxic. Some are dyes and some are pigments. But they all have very low oders. Emulsions often contane alcohol and smell bad. When we did electrostatic spraying or curtain coating,lab or factory, there were always several layers of protection between liquid and people.
    Cheers,
    Bill

    You mean the the "substitute" is not already available premade for another market?

    (I imagine only you make "your" emulsion )

    How is it Toxicity wise?

    Yes. It is mine own little "invention".

    While I have not sent it to a certfied lab for an LD50, I think that the finished 'gelatin substitute' is fairly milde. Certainly not as potentialy hazardous as AgNO3, or as toxic as formalin. I do not have enough space for enough mice for an LD50.

    So I can't put it in my wife's gelatin sweets? Too bad.

    Please remember my offer of a beta tester was not for your LD50 studies!

    Ray;

    IMHO, if I were to offer to have you as a beta tester, I would first like to see some of your emulsion and coating work. This is a suggestion that I put forth to Bill if he considers taking you up on his offer, as it is essential that he see that you are capable of doing justice to his synthetic material in all regards.

    This is intended merely as a suggestion to Bill as something between you and him to reassure him. But, this is what I would do in his place.

    Bill - for a quickie LD50 test you only need 2 mice and 24 hours! ;^)

    Kirk,
    What is the stanerd delivery method? Injection would be easy. I don't think that mice would eat it. Is the injection intraveinus, subcutanious, or musculer?
