Abstract

Production of artistic surface effects or properties comprises applying one or more different liquid or vaporous chemicals onto one or more different metals so that a chemical reaction takes place to form a color on the metal surface. Preferred Features: A covering layer is applied in a further working step. The covering layer is made from a transparent colored lacquer.

Description

The invention relates to a method for achieving special artistic Surface effects or textures, especially in a painting or Artwork, using chemically modified metal. The invention also relates to a painting or picture made according to the process.

Metals have so far been used in art as

• - sheet metal, e.g. B. in icon and panel painting or for finishing z. B. Wood sculptures,
• - sculpture itself, e.g. B. Bronze and steel sculpture.

Sheet metals and sculptures of this kind are rarely or not painted at all because of the application of paint adhere poorly to the metal surface, appear dull and the shine of the metal affect.

The invention has for its object to provide a method that allows it to develop color and plastic motifs on metal surfaces without Paint application to affect the gloss.

This object is achieved according to claim 1 by the following steps: On one or more different metals, one or more are differentiated ied liquid or vaporous chemicals applied, so that a chemical Reaction is triggered, which forms color on the metal surface.

Through the targeted use of chemicals, motifs and thus paintings or Educate images.

For the process according to the invention, metal sheets, plates or moving plates are suitable flat type, solid and hollow body and metal foils preferably on a support brought.

The named can be of the same or different types of metal.

On the metal surface cleaned of grease, dust and dirt, a or applied several different chemicals. By repeated application or / and higher concentration of chemicals can be stronger or / and others Form colors and thus work out the modulation of the image.  

The chem. Connections can optionally be made with another Chemical can be solved again.

A top coat can be applied in a final step for which a clear varnish is preferably used, which reliably presents the image protects against harmful environmental influences.

However, it is possible with transparent, colored spirit varnishes or individual motifs to color the entire area. The dyes of these varnishes are completely disembodied. and hardly affect the gloss of the metal. Modulations cannot They are also often too bright and toxic.

In an unpleasant way, they falsify the color that was chemically formed. After this step, it is advantageous to have a protective top coat made of clear lacquer apply.

Further details and features of the invention are apparent from the following description of embodiments with reference to the illustrations of some after Processes of images already produced according to the invention can be seen.

Show it:

Fig. 1-4 each silver leaf placed on a support and processed according to the invention with potassium polysulfide dissolved in water.

The potassium polysulfide solution causes a conversion of the silver into silver sulfide, the as a very thin layer shows different stages of discoloration of the silver, from delicate gold tones over reddish nuances to an almost black steel blue.

Fig. 1 shows 4 silver leaf ( 2 ) placed on a support ( 1 ).

In this case it would also be possible to replace the silver leaf with a solid one Use silver plate.

In accordance with the procedure according to the invention, potassium polysulphide, which was heavily diluted with water, was applied to form the lightest, golden tones ( 3 ). It takes about 2 hours until the chemical reaction is complete, only then can the result be assessed and further work carried out. Preferably with a somewhat higher concentration of potassium polysulfide solution to form darker, in this case reddish tones ( 4 ).

If the chemical reaction is also completed after this step, it is advisable to use very strongly concentrated potassium polysulfide solution for black-blue tones ( 5 ).

However, further processing of the image can also be done with repeated application the same solution of the potassium polysulfide.

It is advantageous to put the various concentrated potassium polysulfide solutions in front of them Application on the image to test their reaction and thus color strength and change if necessary.

Fig. 2 shows silver leaf ( 2 ) cut according to the motif on a carrier ( 1 ) here papyros. The process according to the invention was continued as described under FIG. 1.

• 1st working step with low concentrated potassium polysulfide solution.
• 2nd step with a slightly higher concentration and 3rd step with strong concentrated potassium polysulfide solution.

Fig. 3 also shows silver leaf ( 2 ), cut according to the motif on a support ( 1 ) Papyros and processed according to the invention.

The development of the method according to the invention is shown here in a color layer ( 6 ), here pastel chalk, which is applied according to the procedure according to the invention and is distinguished by the fact that it supports the motif in its meaningfulness.

Fig. 4 shows silver leaf ( 2 ) side by side on a support ( 1 ).

In this case it would be possible to use a continuous silver plate instead of the silver leaf use.

Fig. 4 is characterized in that highly concentrated potassium polysulfide solution was applied in its entirety by means of a sponge to the silver surface, recognizable by the streakiness of the image.

After the chemical reaction was completed, the motif was worked out using a cyanosodium solution. This cyanosodium solution dissolves the silver compound and the silver ( 7 ) underneath which has not come into contact with the potassium polysulfide solution is revealed.

Claims (8)

1. A method for achieving special artistic surface effects or textures, characterized in that one or more different liquid or vaporous chemical are applied to one or more different metals ( 2 ), so that a chemical reaction is triggered, the surface color on the metal ( 3 ; 3 , 4 , 5 ), which, when used in a targeted manner, forms a picture or painting ( Fig. 1; Fig. 1-4). 2. The method according to claim 1, characterized in that there are metal sheets, plates moving or flat type, solid and hollow body made of metal and metal foils for the procedure. 3. Process according to claims 1 and 2, characterized in that other and / or stronger colors ( 4 ; 4 , 5 ) are formed by multiple application and / or higher concentration of the chemicals and the formation of a modulated and thus plastic by targeted use Motive ( Fig. 1; Fig. 1-4) enable. 4. The method according to claim 3, characterized in that the, by the applied Chemical reaction caused by other chemicals if necessary will be annulled. 5. The method according to any one of claims 1-4, characterized in that in one subsequent operation, a top layer is applied. 6. The method according to claim 5, characterized in that one or several different transparent, colored lacquers in whole or in part on the Metal surface can be applied. 7.
