A VALUABLE DISCOVERY. 
The process, devised by Mr. Bower and perfected by his son, accomplishes 
the object of protecting the surface of iron, and at the same time produces a 
beautiful French gray tint, which obviates the necessity of painting the articles 
treated. The process, which is not secret, consists in heating the articles to be 
coated in a closed chamber by means of carbonic oxide, heated air being made 
to enter the chamber for the double purpose of burning the gas and for combin- 
ing with iron. The excess of air after burning the carbonic oxide gas, combines 
with the iron, forming first the magnetic oxide and then the hydrated sesquiox- 
ide, or common iron rust. By shutting off the supply of air until only enough 
is admitted to turn the carbonic oxide, the rust is converted into a magnetic ox- 
ide. ‘The process is repeated until the film is sufficiently thick for the purpose 
of protection. The application of this invention has been undertaken on a 
large scale, the chamber where the oxidation is now carried on being large 
enough to contain about a ton of miscellaneous articles.
