Hallo,
Does anybody familira with the effect of pouring hot melting metal tin in the palm without harm?? It used a metal alloy called Cerrolow-117. It has a low melting point of 117 degrees. Where I can obtain that special metal?? Richard Gerlitz has sell, name is Trial by Fire, but no more available. Thanks. |

I haven't heard of that alloy, but I posted of another containing gallium, bismuth, and tin, that can be made to melt in your hand.
It's on page 18 (I think) of the Howie Diddits thread at the Secret Sessions forum.
Just hanging out with the rest of my fellow dregs.

My pal,
Thanks. I often heard about Howie Diddits, but can not find the site. can you tell me what is the site?? Thanks. |

Toxicity of gallium is apparently of a low order, but not yet fully established. See the relevant part of the MSDS here and proceed with caution.
"Gallium and gallium compounds may cause metallic taste, dermatitis and depression of the bone marrow function. Large doses may cause hemorrhagic nephritis." Yours, Paul |

Seriously though, how about Indium, that was the original ingredient in place of gallium, but a somewhat higher melting temperature. Howie Diddits is a special thread in the Secret Sessions forum in the Banquet Room. It's got a sticky bun, so it's always at the top, hard to miss.

Mystician,
Indium is far worse. From the MSDS cited above: "Exposure to indium compounds may cause pain in the joints and bones, tooth decay, nervous and gastrointestinal disorders, heart pain and general debility. Experiments with animals also indicate that indium may cause reduced food and water consumption with weight loss, pulmonary edema, pneumonia, blood, liver and kidney damage, leg paralysis and damage to the brain, heart, adrenals and spleen." Makes you take a different point of view about card tricks, doesn't it? Yours, Paul |

Thanks for the infos.

Drwilson,
You didn't mention from the MSDS's cited above, all this from casual handling of small portions of these materials ? Or is this more along the lines of the FDA sacharin tests of the '70s where they fed enough to rats in one day to last 100 humans a lifetime ?

Mystician,
Those MSDS sheets tend to be cautious. Read the MSDS on salt (sodium chloride) someday for comparison. That said, I personally wouldn't do this, even if I could get the metal, which is hard these days. The studies on these elements are limited. Not only are you exposing yourself to this stuff, which is your own business, but you are also potentially exposing your audiences. For the sake of comparison, fire eating is not great for your health. Your are drinking fuel every time that you do this. You risk getting burned. If you do the blast, you risk blowing half your face off or your lungs out if you have one bad day, just one (Was this your card? No? Sorry folks that happens sometimes...). Yet the danger to the crowd is minimal. With handling these metals, you are working close to other people with a warm alloy. This is really a closeup effect. Notice in the MSDS they tell you to work in a fume hood with the gallium-indium eutectic. This means that there is metal vapor, like that from mercury, that you, and the people watching, are inhaling. If you drop any (seems likely), it sits there in the performing venue, maybe someone's house, waiting for the dog to eat it or a toddler to stick it in his mouth. I have done chemical effects that I can't discuss in detail here that involve chemicals that are dangerous if handled improperly, but which did not present the toxicity risks posed by this effect. One example is Andruzzi's Demon Dirt, with which you are likely familiar. I haven't done this in a long time, because to my eyes it looks just like what it is, a chemical reaction causing fire. There are a lot of things of this type that I did in my youth from chemistry-demonstration books. Along the lines of this effect, though, is something that I would do in a suitable setting (not a kid's birthday party). It is possible to dip your fingers into molten lead without injury. Here you are demonstrating the effect that this gallium/indium business is attempting to simulate, but you are doing it for real. The apparatus necessary to melt the lead makes it clear that high temperature is involved, a strength that the gallium/indium effect lacks. It is so obviously real that the audience just has nowhere to go with this. PM me for details. I am just putting this out there to show that I am not a wimp or a wet blanket, just that I don't care for the effect that is the topic of this thread for the reasons that I give. Yours, Paul |
