ISTR that there is a word for the chemicals used to artificially age
or color wood via a chemical reaction.
Examples would be sodium hydroxide, iron acetate, potassium
dichromate, or nitric acid.

This is distinct from coloring wood with dyes or stains or toning it
with colored clear finishes.

Does anybody know what the proper term is for the technique or the
chemicals used?

Now now, don't get angry...

OK, just kidding. That's what you call it when you use ammonia
vapor, but not
when you apply the chemical in aqueous solution, right?

Ooooh yeah.

One word that would apply to sodium hydroxide and nitric acid when in
contact with organic materials is that they act as 'denaturants.'
They alter the structure of proteins, a process called denaturation.
A drop of nitric acid will produce yellowish brown stains on skin.

As to the other chemicals, I don't know if the same thing applies. I
seem to remember potassium dichromate had a strong orange color, but I
think you're looking for effects produced through a chemical
reactions.

There is no one word that characterizes the use of "chemicals" to color
wood. Since they react with the wood itself, unlike a pigment or dye,
perhaps "reactives" might be a good shorthand. Fuming is specific to
ammonia. Acids like nitric and sulfuric as well as things like potassium
permanganate are all oxidants. They color the wood by oxidizing the wood
components. Dichromate both oxidizes and dyes the wood. Think of oxidants
acting as a very controlled "burn".

Correct, direct application is not fuming. I don't remember what he called
it but David Marks once used this on one of his shows. I believe that
potassium
dichromate was what he used.

I think the term is "distressing", which also covers deliberatly damaging
furniture to make it look old or antique.

That's called "Minwaxing" here. titter

Yes, I can remain still on an escalator for quite some time.

I was thinking aback about DM also but I thought he was using the
chemicals on metal surfaces rather than wood.

He did a lot of that with metal and called it patination IIRC.

I remember the metal piece but I thought that he also did one with wood.
Could be wrong. Long time ago.
