    Here is a quote from The darkroom cookbook
    By Stephen G. Anchell
    It is an excellent and modern book and I think everyone who does B&W work should read it.
    Not for safety reasons but so you can play better in the darkroom.
    It’s lots of fun to try out the formulas in this book.

    Perfect! Now I really don't want to use it.

    I'm just trying to point out that everyone comes forth with their opinions and subjective advice, yet not much objective information. Chock it up to being an advocate for the devil I guess...
    Here is my objective information. You are young and most likely have not seen any of your friends DIE as a result of poor decisions. I have. I did a LOT of STUPID things in my youth. I hope my children, who I love very much, will not try any of the foolish things I did when I was younger.

    Learning how to handle chemicals is probably something you really don't want to learn over the interweb. Years of college chemistry labs and workplace training are really the way to lean this stuff. And even then, there are some things where there is a general lack of real info, like the dimethylmercury example above.

    I would not recommend using mercury compounds in the home or commercial photo lab these days. They are not what we consider "safe" for general use these days. There are safer ways to achieve similar results nowadays.

    That said, I used mercury intensifiers my self as a teenager 30 years ago.

    Look, I don't even want to use mercuric chloride or any mercury compound for that matter, but if you look through the thread, very few actual FACTS were given. That's all I'm getting at!

    Excuse me now, it's the time of day that I usually play with broken thermometers....

    Ordinary precautions should keep you reasonably safe when handling small amount of mercury (II) chloride. Metallic mercury has a fairly high vapor pressure and is therefore much more dangerous. That does not mean it can be handled carelessly, spilled around the lab, or ignored as a poison. But most countries and localities have some very strict rules on the purchase, shipment, use, and disposal of mercury compounds that must be obeyed.

    There was one FACT presented OVER and OVER again. DO NOT USE MERCURY IF AT ALL POSSIBLE.

    I\'m with Chris here. You tell children no.



    You tell adults it is a bad idea, but if they must then here are the rules. But it is still a bad idea.

    In sublethal doses mercury II attacks the central nervous system. It was used for a long tine in felt making hence the term "mad hatter".

    Google "minamata disease" for nervous system effects. The famous photographer Eugene Smith did a series on the victims.

    This is exactly what I'm talking about! No facts, just "NO NO NO NO".

    But oh well, I think my point has been made. Michaelbsc's got the idea...

    And Gerald thank you for pointing out that disease; these are the kind of "facts" that I think will make people do the right thing by their own volition.
