Sometimes we would darken-in engravings with a product called stove black. It imparted no gloss whatsoever but I don’t know if that’s even around anymore.
Ahhh…. This takes you down the rabbit hole of linseed paint!
Traditional Stove Black is linseed oil or boiled linseed oil with either graphite, charcoal or ‘soot’ (from an oil lamp or wood stove etc)
There are still some good products around:
Allbäck Stove Blacking Fireplace Paste is solvent-free and can be used on any surface that becomes very hot. The graphite pigment remains black regardless of temperature. Great for protecting metal surfaces from rust.

Linseed oil and boiled linseed oil is a lost product that’s worth exploring. There are now companies that are producing PROPER oils….
Like most other things, corporate America found a way to totally ignore the important process and replace it with cheap chemical dryers etc…
IOW: boiled linseed oil from home depot is NOT the same and won’t work the same…
Anyway, I’ve been using Allback Swedish oil and paint for different products around the farm here. Very good stuff…
I use their linseed wax (linseed oil and bee’s wax) that is magical on your wooden handles on yard tools etc.
Also, (non-boiled) linseed oil is fantastic for seasoning your cast iron cookware!
Handbook for your perusal:
I can see where a linseed product ‘may’ work very well here (remember… its where all art paint came from before modern replacement)
