Builder wants green-blue patina on steel staircase

Modern Masters Green Patina
from eBay or
Amazon

(affil links)

How do we patina steel to obtain the greens and blues of bronze patina? We are building a 'floating' circular staircase with steel sheets on the bottom and partway up the sides and we love the soft hues of bronze patina.

If you haven't already..try contacting Ron Young at SculptNoveau in Escondido, CA. He's developed a bunch of great finishes for steel, bronze, etc and should have something that fits your needs.

I have a solid bronze threshold (Pemko) with a brass finish. I was wanting to know if there is a chemical process to speed up the patina to make it look darker?

Hi, Scott. If it has brass lacquer ⇦ this on eBay or Amazon [affil links] on it, you must first remove the lacquer with lacquer thinner ⇦ this on eBay or Amazon [affil links] Warning! flammable! . Then you can blacken it up quickly with liver of sulfur ⇦ this on eBay or Amazon [affil links] or brass darkening solution ⇦ this on eBay or Amazon [affil links] . But it's strong stuff, both in terms of being a little noxious, and in how fast and how black it will make it. Good luck.
