Color print on steel and glass by oxidation with heat or chemistry
Attachment 82702Attachment 82702
I was surfing in 470000 Russian thesis database and I found an research on laser oxidation of metals for obtaining color patterns. I returned to Google and found above stainless steel piece made by Singapore researchers with nd yag lasers. Mechanism : Heat causes an chromium oxide layer at bottom and iron oxide layer on top of the first and different heats increase the iron oxide layers and change the color.Similar mechanisms apply on glass.
I found electricity is used to create automobile point welds and same technology could be used to create controlled heat and controlled color large pixels to form an lower resolution color print on stainless steel or glass. If I am not wrong , as we see at dish washing machines , if we ground the piece , no danger.
Is there a simpler , chemical way ?

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.
