      ATTENTION Forum Database Breach   03/04/2019

      There has been a breach of our database. Please make sure you change your password (use a password manager, like Lastpass).
      If you used this password anywhere else, change that too! The passwords themselves are stored hashed, but may old accounts still had old, insecure (by today's standards) hashes from back when they where created. This means they can be "cracked" more easily. Other leaked information includes: email, IP, account name.
      I'm trying my best to find out more and keep everyone up to date. Discord (http://invite.gg/TerraFirmaCraft) is the best option for up to date news and questions. I'm sorry for this, but the damage has been done. All I can do is try to make sure it doesn't happen again.

TFC in Harry Harrison's "Stonehenge"

3 posts in this topic

Found another nice quotation about metallurgy from a book (in addition to Jules Verne's one).

This time - from Harry Harrison's "Stonehenge", which is actually about Greek and Atlantis warriors fighting over a tin mine to be able to produce bronze.

"

It was a war over a resource as precious as the one that names our own Petrochemical Age. Not oil, but tin. Without tin,
there could have been no Bronze Age. For at the very dawn of metallurgy it was evident that copper alone was too soft to
make durable tools and weapons. Tin was essential, but almost impossible to find. Yet when combined at a proportion of
one to nine, it transforms the abundant, more malleable copper into hardened bronze. Too much tin, and the bronze is
too brittle, like the raw hardening agent itself; too little, and the bronze is too soft, like the copper it melds with. But it
is scarce; the more so for the ancients, who didn't dig deeply for it as we do, but who searched for nodules of cassiterite in
naturally open tin streams. There are none of those nut-like nodules of tin oxide left anymore, the surface of the earth
having been picked clean a long time ago.

Exactly like near-spawn area :)

This is one reason why Great Britain was strategically important - (relatively) large deposits of tin in the South West.

So much so that they were known as the "Tin Isles" by some in Roman times.
