Chemical Patination of Metal and Glass
There is an chemical answer to patinate and oxidate the metal. Which sculptors used for thousands of years. Patination recipes are sometimes dangerous and I dont know any for steel or glass. I will ps. here if I can find.
PS: Sone say dung the answer for glass. Louis Comfort Tiffany and his men created the most beatiful color glass on earth with some say with carbonic acid patination and ammonia salts .
A book reports Tiffany irridescent glass has been made with spraying silver or bismuth in to a fire and than from there on to molten glass. When the glass piece went to closed furnace , wait the fire turns to green and they spray tin chloride . They measure the heat with first fingers nail.
Second irridescent formula is dropping in to molten glass copper gold alloy , gold is ruby , copper is amber.
They call these glasses carnival glasses after 20's which Harry Northwood invented poor man's Tiffany and produced every color. I am after that recipe now.

PS3:Carbonic acid is the chemical compound with the formula H2CO3 .
PS4: I read many times , Tiffany used Carbonic Acid at his glass patinations but I read silver in glass and tin chloride spray on to hot glass also.. Carbonic acid mechanism is works for antique glass , his works differantiate from the old with non cracked clean and new surfaces. He did see these examples while visit in Europe and when came back to America , he requested the same look from the Nash.
PS5:Stainless steel is only be patinable chemically to gold and gold brown . Normal steel could be rust only.
