Definitions
- T he present invention relates to improvements in a process for crystallizing brass sur-- faces whereby an ornamental surface is produced upon the exposed portions thereof, either upon sheet or cast brass, such surface to be finally lacquered so as to retain the desired flaked or crystallized surface and coloring accomplished by the present process.
- the first step consists in dipping the cast or sheet brass in a solution containing one part of nitric acid and two parts of sulfuric acid. After remaining in this solution for a period of time approximately from five to ten seconds the brass is removed and rinsed in clear, cold water. This step of the process results in the removal of all scale, dust and grease and brightens thebrass.
- the second step consists in dipping the brass thus affected by the nitric and sulfuric acids in 'a solution of 'water in which 8 ounces of potassium cyanid is dissolved to After the brass reeach gallon of water. mains in this solution for a predetermined period of time approximately from five to ten seconds the same is removed and dipped This step of the process prevents the brass from tarnishing.

PROCESS OF CRYSTALLI IZING BRASS SURFACES.
Ito Drawing.
To all whom it may concern:
Be it known that l, O'r'ro ROY HAsnNonR, f;
' State of Indiana, have invented a new and useful Process of Grystallizing Brass Surfaces, of which the, following is a specification.
T he present invention relates to improvements in a process for crystallizing brass sur-- faces whereby an ornamental surface is produced upon the exposed portions thereof, either upon sheet or cast brass, such surface to be finally lacquered so as to retain the desired flaked or crystallized surface and coloring accomplished by the present process.
lln carrying out the present process, there are substantially four steps to produce the completed article.
The first step consists in dipping the cast or sheet brass in a solution containing one part of nitric acid and two parts of sulfuric acid. After remaining in this solution for a period of time approximately from five to ten seconds the brass is removed and rinsed in clear, cold water. This step of the process results in the removal of all scale, dust and grease and brightens thebrass.
The second step consists in dipping the brass thus affected by the nitric and sulfuric acids in 'a solution of 'water in which 8 ounces of potassium cyanid is dissolved to After the brass reeach gallon of water. mains in this solution for a predetermined period of time approximately from five to ten seconds the same is removed and dipped This step of the process prevents the brass from tarnishing.
A third step consists in placing the brass in sawdust which is dampened or moistened with a solution of water, in which to each half gallon thereof, there is 10 ounces of salammoniac and 2 ounces of blue vitriol. Care must be taken that the sawdust is not too moist, it merely being dampened. After topies of this patent may be obtained for Specification ofl'ietters Patent.

, remaining in the sawdust approximately for apelriod of from one to five minutes the brass is removed from the sawdust and rinsed well in clear, cold water and finally dried-lay dipping in and removing from boiling water. This step of the process results in the crystallizing of the surface of the brass.
The fourth step in the process consists in lacquering the surface thus affected, by the various steps heretofore described with a chip lacquer, it preferably being placed thereupon to produce a brown shade.
It has been found with this process, that the surface of the brass either in sheet or cast brass is crystallized or flaked, and
. that a beautiful finish is accorded thereto if this process is carried out with care.
What is claimed is:
The herein described process of crystallizing brass surfaces, which consists first in dipping the brass in a solution containing one part of nitric acid and two parts of sulfuric acid and maintaining the brass in said solution from five to ten seconds, then removing the brass and washing it in cold water and dipping the brass in a solution containing eight ounces of potassium cyanid to a gallon of water, where the brass is kept for from five to ten seconds, after which the brass is Washed'in cold water, and then placing the brass in sawdust which contains a mixture consisting of ten ounces of salam moniac, two ounces of blue vitriol to a half gallon of water, the brass being kept in the sawdust for a period of from one to five minutes, after which it is washed in cold water and finally dried by dipping it in and removing it from boiling water.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
