Ebonising

Ebonising is a process for darkening wood, giving it an appearance similar to ebony, hence the name.

It is particularly used for pianos and fine furniture.

Processes

One process uses iron dissolved in vinegar as the darkening agent. The ferric acetate thus formed reacts with the tannin in the wood.[1][2]

gollark: Allegedly, Discord.
gollark: It randomly breaks for no apparent reason, seems to want to log me out if I open it in multiple tabs (browser version), and seems to just be a bloated monolith with way too many things.
gollark: It's an Electron app, so it ships yet another browser for no good reason.
gollark: Oh yes, MICROSOFT TEAMS.
gollark: Modern computers are *extremely fast*. Billions of instructions per second *per core*. Yet somehow software gets increasingly terrible such that just having a chat app like this open (in a browser) uses a substantial fraction of that, and enough memory to store several hundred *novels*.
