PROCESS OF COLORING FOIL.
No Drawing.
This invention relates to a process whereby tinfoil is givena gold color andthe manner in which such operation is carried out.
The objects of the invention include, among others, the production of a gold colored foil, a process for converting the present tin foils into gold colored foil, and in the provision of a means whereby conventional foil is converted into a new product possessing the characteristics of tin foil or alloyed foil but having a golden color.
These objects, and such other objects as may later appear, are obtained by the novel process which is hereinafter outlined, step by step, in the manner in which such steps are arranged, and the product resulting from such process.
In carrying out the process, tin foil or alloyed foil is prepared in the usual manner.
Such tin foil, after its manufacture, in any of the conventional methods now known in the art, is washed. Such washing is for the purpose of freeing the surfaces of the foil from impurities. During the course of manufacture, grease or soap may come In contact with and adhere to the upper or lower surfaces of the foil sheet.
The preferred washing of the foil is accomplished by passing the foil through a wash mill. Gasoline is the most desired washing medium, and both surfaces of the tin foil sheet are thoroughly cleansed therewith. Other materials for this cleansing operation could be employed, but at the present time, gasoline of standard quality apparently produces superior results.
lVhen the foil has been washed to the extent indicated, it is either spooled or cut' The higher the temperature, within specific limits, the deeper the shade of gold color which will be produced.
The time which the foil is kept in the oven, hereinbefore referred to as from four to twelve hours, depends generally upon Application filed October 52$, 1825; Serial No.1 65,052.
the widthof the foil r-which 'is under treatment. The wider thefoil, thelonger it must i be kept under the heat of the oven.
A test to determine whether the. foil isis retained in the oven, from which the heat is cutoff, the oven being allowed to cool off slowly, such slow cooling completing the coloring operation.
When the oven shall have become cooled, and foil under treatment will likewise be come cool, it is then ready for removal. As previously stated, whether the temperature was three hundred ninety degrees Fahrenheit, four hundred degrees Fahrenheit, or somewhat above the last mentioned degrees, will determine the tone of the gold color imparted to the foil. The higher the temperature, within certain limits, the deeper the color of gold.
It is quite manifest that the process of coloring foil by means of heat treatment may be accomplished in some apparatus other than an oven; and that the specific temperatures, or the time of the exposure. to heat may be modified to produce the result heretofore obtained. It is therefore my intention to claim the invention as a process of changing the color of tin and alloyed foil to gold by the application of heat thereto in an oven or other heating apparatus and the product obtained thereby, it being understood at this time that the process involved is one of oxidation.
lVhere the words foil and tinfoil are used. in the appended claims, a foil of pure tin or of tin and alloys is meant.
I claim:
1. A process of converting tin foil of a silver color into a gold colored foil by the application of heat thereto for a predetermined period of time.
2. The process of changing the color of tin foil by oxidizing the surfaces thereof while contained in a heat producing apparatus at a predetermined intensity of heat.
3. The process of converting tin foil of a silver color into a gold colored :toil by the application of a low heat thereto for a predetermined period of time and in the presence of oxygen.
4. A process for changing the color of tin foil which consists in baking it in a heat producing apparatus at a temperature of approximately three hundred ninety to four hundred degrees Fahrenheit.
5. A process for the production of a gold colored tin foil from tin foil which consists
