Richard,

As I said, I am no chemist, and I am a little confused now.

The introducing of carbon acid to mix with the vinegar fumes will promote the chemical reaction. That was what I said, based on an artichle (in Danish).

You are probably right that the fumes should be called Carbon Dioxide, because it is also named CO2.
The CO2 is formed by the fermentation of the manure, and that is also the reason why it sometimes contains Hydrogene Sulphide that can miscolor the lead powder. Wherefore the manure is often replaced by used tanbark that did not miscolor the lead.

Another way of bypassing the problem of miscoloring was to get the CO2 from a brewery, leading the air from the fermentation directly into the room where the lead was.

I have read about 2 other methods to produce CO2.:
One is to simply drop some Baking Powder into the vinegar, that will produce CO2 into the room where it should be. CO 2 is more heavy than air and will stay in the bucket.
The other is to add HCL Hydrogenclorid, thinned, into crushed Marble, it also produces CO2.
The Baking Powder model is the most tempting.

What do you think?
