Citizens,
Permit me to add a bit of trivia tidbit to the conversation.
The tendency for 'real' wrought to have layers of ferrous silicate spicules, in it, made it rust resistant. The use of wrought iron was continued for sea-side bridges, continued many years after it fell out of favor for other construction, elsewhere. Those wrought iron bridges did not deteriorate as fast as steel bridges
Some of the members, here, have capitalized from that situation by collecting, or scavenging, or even buying the demolished bridge scrap and selling it to other smiths.
I bought some of it from a chap, here, on I-forge a while back.
Lovely stuff.
SLAG.
