Turning bronze green

Post by king11 »

I know bronze will tarnish with time. Is there any chemical I can buy that I can brush on to turn bronze green immediately?

Bronze Coloring

Post by tartansailor »

To Color Bronze.- Bronze articles acquire handsome tempering colors by heating. In order to impart an old appearance to new objects of bronze, they may be heated over a flame and rubbed with a woolen rag dipped in finely powdered graphite, until the desired shade is attained.
Or else a paste is applied on the article, consisting of 5 parts graphite, 15 parts rouge in enough alcohol to make it workable. After 24 hours brush off the powder residue.
A hot solution of 4 parts sal ammoniac, 1 part sorrel salt in 200 parts vinegar may also be brushed on.
Another way is to dip the pieces into boiling solution of 20 parts cupric acid, and 10 parts sal ammoniac, dissolved in 60 parts vinegar.

[double double toil and trouble;
fire burn and cauldron bubble]

Hope this helps,

Funny... those who want/try to keep it shiny will tell you that it turns green virtually overnight. :)

tarnish

Make sure it isn't coated with something to keep it from tarnishing. I bought new cleats for my Ty and they looked pretty good by the end of the season. Salt water is a good thing, Steve.
