Hello everybody. I'm a long time lurker and learner. I have a great deal of respect for the effort and care that has built this site. I'll try to contribute as I learn just a little bit more.
I have read several posts related to Zinc in the forum. I recommend reading the Wiki page about zinc metal: Zinc - Wikipedia
Zinc metal can act as a strong acid. When Zinc dust is added to an acid solution it evolves hydrogen gas. If the acid is HCl, the Zinc metal forms ZnCl2 and hydrogen is liberated. When this happens, some of the free hydrogen in solution might pass near and bond with an oxide group to form an OH radical. When more hydrogen encounters the OH radical, a water molecule is formed and the oxide will be reduced. To summarize, in an acid solution, Zinc metal liberates hydrogen and it is the hydrogen that reduces DMT-N-oxide to DMT. The byproducts are water and ZnCl2.
Zinc can be toxic. The Wiki article mentions that swallowing copper clad Zinc pennies can corrode your stomach. The article describes someone who died from swallowing 425 "post 1982" pennies. Keep in mind though, lots of reletively harmless things contain Zinc. For instance, brass metal contains around 35% zinc metal and you don't really worry about touching or using brass or Zinc containing items (handrails, cookware, tobacco pipes, galvanized cans, batteries, musical instruments, galvanized iron etc.). You need Zinc in your diet and the USDA recommends ~15 mg per day. Under the right conditions it's possible to vaporize Zinc metal at around 285 degrees C (so a match or torch might be able to do this). To summarize, a little Zinc in your body is a good thing but it wouldn't be good to allow too much. Be careful.
Many metal products contain Zinc metal but many things containing Zinc aren't made of pure Zinc. One type of item that is made of pure Zinc is a device that is used on metal hulled boats (and ships) to prevent corrosion. This device is actually called a "Zinc". In the case of a steel hulled boat, a "Zinc" acts like a battery delivering electrons to the steel hull so that Iron Oxide cannot form (ie the boat can't rust). Most marine supply stores sell Zinc bars for this purpose. Just ask for a "Zinc" for rust prevention. They will have many shapes and sizes to choose from. In order to work properly, a marine "Zinc" must be made of very pure metal. Marine "Zinc" purity specifications have been defined (by the US Navy) and are listed below (in percent impurity):
ZINC MIL-A-18001-K (%)
Iron (Fe) 0.005 max
Cadmium (Cd) 0.025 - 0.07
Lead (Pb) 0.006 max
Aluminum (Al) 0.1 - 0.5
Copper (Cu) 0.005 max
Others (each) 0.10 max
Zinc (Zn) remainder
Marine "Zincs" are very pure (perhaps 10X purer than pennies).
Sincerely....cker
