Looking for an appropriate method of consumption. The machine seems like a good solution, but does anyone worry about the dangers of inhaling hot metal fumes? It seems like that could potentially be very bad, and we wouldn't know until someone got serious symptoms.

So, does anyone have any further information on whether metal mesh used as it is in the machine is safe or not? It seems that some of the primary concern comes from chromium in stainless steel, and zinc in brass. There's some information that makes copper seem questionable as well.

Metal vapors and metal oxide vapors can be harmful, as your links indicate. But metals and their oxides vaporize only at very high temperatures (in the neighborhood of 2000°F). This is why the linked ailments are often associated with metal refineries, welding, etc. and either prolonged exposure or very concentrated exposure. Unless you were to either completely oxidize metal mesh and inhale the fumes, or liquefy metal mesh and then inhale any resultant fumes, you will not be exposed to harmful vapors.

Even glass if heated sufficiently could be harmful. I would guess that if glass was heated to its boiling point and the fumes were inhaled, then one could get sick. This does not mean that it isn’t safe to use glass. Cookware is typically made of stainless steel, copper, or aluminum, is heated to high temperature (300-400°F) and is considered safe.

At normal DMT vaporization temperature, none of the metals in question will produce vapor. They are safe.

Thank you, this is what SWIM was hoping for and half expecting. Just wanted to clear up the concerns and ask the question for others who had the same one.

Count me in 2! i use wire mesh and have always got paranoid about inheailing unwatned fumes!

Very useful information here.

When we talk about metal mesh, we are referring to something like this, not woven metal screens.

I was looking at the Chore Boy FAQ page and found these interesting items:

Be sure to gently burn off the oil/lubricant before using.

edit: scrubbers also are available in stainless steel and brass

I wonder if the stainless steel vaporizing pad for the volcano (volcano liquid pad) could also fit a machine. It does work as a metal mesh for the vaporgenie, but I never tested for the machine. It is a more 'tight' metal mesh, but maybe one can pull it and make it 'looser'. And since its so cheap, I guess it would be worth a try since it is definitely safe for vaporization. If you do try it, let us know

I’ve looked at photos of liquid pads, and it seems that they’re made of wire rather than ribbon. The scrubbers are made of metal ribbon – the individual strands have a thin rectangular cross-section in contrast to wire, which of course has a circular cross-section.

The result is that ribbon has a much higher surface area per unit length. A smaller amount can be used to effectively hold a liquid. I haven’t tried a liquid pad, but my guess is that after cutting one to size, loosening it up, etc. it would be about as effective as using multiple screens.

If anyone tries a liquid pad, I’d be interested in hearing how it works.

Did you mean something along these lines of wire mesh?

Check out some of the galvanized and stainless steel very fine wire cloth there and you will have a better idea.

Screens and woven metal "cloth" are not as effective.

I’ve already posted this photo elsewhere, but here it is again:
