the appropriate place for further discussion. If the reader has a difficult time gathering
the context, then reread the Welcome thread under "Hello, I am Kareltje".

Nice piece of work.
But I impatiently wait for articles about tin (Sn), zinc (Zn) and iron (Fe). These may not be aal construction materials, but they are abundant in containers for food and drinks, kitchen utensils and farm or garden tools.
What about a tinned can for collecting distilates? I found a watering can of galvanized iron that looks perfect as a helmet for a still. Can I use it? I have a iron column or iron fillings for a copper column. Is that a problem?
What about toxicity, attacks by acids, transports by gasstreams etc.?
And what about other metals? I saw a still of titanium for sale (made by a engineer of a aircraft company). Is this safe?
I answered based on what I understood. Which is this:
Are these metals safe for distilling alcohols? You mentioned galvanized iron specifically, and tin for collecting in and wanted info about zinc and iron. So, if I misunderstood what you were asking. Please set me straight.
And then this:

I suppose you are refering to the first part of the article. I did read it, but you did not read my questions. I am not so stupid as to make a boiler of a tinned can or a galvanized bucket: I know very well what tin and zinc are used for. But a helmet is filled with a hot mixture of water and alcohol and that is supposed to be neutral. A recipient is supposed to be filled with cold distillate, also supposed to be neutral. Strong and hot alcohol may leach out plastics, but I wondered about the leaching out of metals and alloys by neutral alcohol.

Your arguments sound like: "The earth is flat and the sun revolves around it and everybody knows that and so it is, because it is the wellproven truth."
On the other hand: maybe this corner of the forum, especially for newcomers, is not the right place to discuss these matters.[/quote]
Yes, of course the earth is flat. And the sun revolves around it. Who said it wasn't?
Was it Kepler, Galileo, Newton, Einstein? Galileo was put under house arrest for
believing otherwise. I'm being facetious of course.
Cetain theory becomes accepted fact when a body of experts have observed it enough
over time that it is no longer questioned. "quoted from a physics class by bernstein"
Now you post a link to an article that is food related and has no bearing on distilling hot alcohols. And then ask a question of whether it is safe to use a galvanized watering can as a
helmet in part of your still? Is that correct or am I missing something? And then state that the vapor that passes through the helmet is "neutral", as if to say, (and I am only guessing here), that somehow it is less volatile in vapor form on the metal than in the boiler. Am I right? Or not?
I admit that I depend a lot on the senior members experience of this forum and do not claim to have all the answers. It has been well documented on here as well as other studies what is safe to use for distilling. If I have missed something, I will gladly stand corrected.
As to the science of it all, I have spent a great deal of time studying physics and chemistry, so I am not completely ignorant to most theories and especially chemical reactions. And yes, I do lean heavily on the current accepted literature available, simply because I don't have time or a lab to do my own tests. Even if it says the earth is flat, I would believe it because as Isaac Newton said: " If I have seen further than others, it is because I have stood on the shoulders of giants".
In closing, your questions are valid and open to a real discussion without prejudice.
