Blueing & other metal patinas
« on: July 16, 2017, 11:07 AM »
Looking to start a thread to share info on metal patinas.

Latest project is another live edge table from the trove of slabs I hauled home from Amish country a while back. Not much new on this table but I used raw steel hairpin legs and finished them with cold blue, turned out great with a nice deep blue/black color. Finished them with a light coat of Camellia oil.

Top is finished with heavy Surfix.

After that I started bluing everything in my upstairs workroom while listening to audiobooks at night.  [big grin]

I am aiming to replace some metalworking equipment that I lost in Sandy and start doing some mixed medium projects. YouTube is loaded with makers doing really fun stuff with wood & metals.

Anyway, looking for input from anyone with experience with patina's for steel, AL, stainless, etc. I have been looking at the offerings on sculpt nouveau, they are interesting but expensive to do trial & error with when I am not sure what I am looking for.

Input is appreciated. 


As of 10/17 I am out of the Dog business and pursuing other distractions. Thanks for a fun ride!

I've used vinegar & salt on copper to get a blue-green color. The only problem is that the patina coat is very fragile and tends to flake off. A driving rain & hail will peel the coating off.

Here's a picture of what's left after 8-10 years.

Nice job. Is the blue color made of resin?

Richard. I like Birchwood Casey Presto Black. It's a room temp agent.

Sculptnuveau is not a bad place to go to. Most of the manufacturers only sell in one gallon minimums. Sculpt repackages down to 8 ounces on most stuff.


Nice job on the table.

You might want to check your local library or local universities to see if they have a copy of the below book you can view or check out. The book is only for copper, bronze, and silver alloys, but it's 370 pages.

ASME handbook 5, covers surface finishing for metals including plating and phosphate finishing etc.
