What kind of printing process is used for platinum prints?
The platinum print process is based on the characteristics of light-sensitive iron salts, which react with platinum salts to form platinum metal. A sheet of paper is coated with a solution of these salts to make it sensitive to light.
When was the platinum print patented?
William Willis was the first to patent the platinotype process in 1873 (British Patent No. 2011, June 8, 1873), and again in 1878 and 1880, which he leveraged to gain commercial success in the manufacture of platinum papers sold through his Platinotype Company for professional and amateur use.
How can you tell the difference between platinum and palladium?
The difference in color between palladium and platinum is very minimal. Platinum rings are generally about 1 shade whiter than palladium, but there truly is a very small difference. Unlike white gold, both platinum and palladium are not rhodium plated since they are naturally a bright white color.
How do you make palladium?
The production of palladium starts usually from the residue of the production of another metal, typically nickel. The chemical differences between the metals in this residue is used to separate them. The first step is dissolving the residue in aqua regia, which will allow all the metals to form their nitrates.

Who invented platinum print?
A platinum print is made with paper containing light sensitive iron salts and a platinum compound, rather than the conventional silver salts, exposed in daylight in contact with a negative. The process was invented in 1873 by William Willis and made commercially available in 1879.
Does a magnet stick to platinum?
The quick answer is no, Platinum on its pure form is not magnetic (a paramagnetic metal).
Does palladium stick to a magnet?
Palladium isn’t magnetic. If the piece you have is a forgery, it may contain iron. This is because iron is an inexpensive metal that’s relatively easy to mold and shape. If your piece contains any amount of iron, it will react to a magnet.
How are platinum prints made?
As with most historical photographic processes, a platinum print is made by placing the negative and emulsion-coated paper in direct contact. Therefore, the size of the photographic print is equal to the size of the negative. Platinum prints have a different “look” from silver gelatin or digital prints.
What is Palladium photography?
Platinum palladium printing is a traditional photographic printmaking technique dating back to a period in photographic history that predates silver gelatin prints. The prints are exposed by UV light, and were originally exposed by the sun.
How do you print platinum?
Is palladium better than platinum?
Of the two metals, platinum is stronger than palladium, but again both metals are strong enough to be used for engagement rings or wedding rings that are worn daily.
What color does palladium burn?
-Relative to platinum, palladium will form a bluish oxide film when heated in a Bunsen flame and then, unlike base metals, will if heated in a reducing flame revert back to a silver colour.
How do you test platinum with hydrogen peroxide?
You can buy hydrogen peroxide at most drugstores or grocery stores. Step②: Wait for the chemical reaction to occur. The precious metal platinum is a strong catalyst for hydrogen peroxide. If the precious metal is pure platinum, the hydrogen peroxide will immediately start bubbling white.
