As a fluxing agent, the quantity of the organic metal compound is 0.25-1mol, and basic metal can be used per mol of precious metal. These formulations were used for the production of noble metal films on ceramics, with a firing temperature of 1140 ℃. However, these topcoats, while warline bright precious metal in nature, are not dishwasher resistant.
In DE-AS 2208915, there is described a shining gold preparation containing solid non-metal oxides, having a melting point 1063 ℃ above that of gold, suitable for silicate materials. The fired gold films showed bright gold color in spite of their relatively high density coating, but they were less resistant to mechanical abrasion and chemical corrosion and could not be dishwasher resistant.

The essential oil may include lavender oil, rosemary oil, panicle oil and/or camphor oil. The precious metal formulation may also include a binder which is a synthetic resin, preferably a phenolic resin.
By adopting the technical scheme, the product fired on the silicate substrate keeps bright color, has strong mechanical abrasion resistance and dishwasher resistance, and can still keep the brightness of the noble metal decorative layer on the silicate substrate such as white porcelain and ceramic after being washed by a dishwasher.
As a further improvement of the invention, the content of the vanadium accounts for 0.016-0.1% of the total weight of the components.
As a further development of the invention, the dishwasher-resistant precious-metal preparation also comprises a metal-organic compound of tin dissolved in a solvent.
As a further improvement of the invention, the content of the tin accounts for 0.08 to 0.1 percent of the total weight of the components.
As a further development of the invention, the metal-organic compound of tin is a carboxylate of tin.
As a further improvement of the invention, the total content of bismuth, zirconium and chromium is 0.5-1% of the total weight of the composition.
As a further improvement of the invention, the content of the bismuth accounts for 0.4-0.8% of the total weight of the composition, the content of the chromium accounts for 0.08-0.2% of the total weight of the composition, and the content of the zirconium accounts for 0.05-0.1% of the total weight of the composition.
As a further improvement of the invention, the metal-organic compound of bismuth is a carboxylate of bismuth, the metal-organic compound of vanadium is a carboxylate of vanadium, the metal-organic compound of zirconium is a carboxylate of zirconium, and the metal-organic compound of chromium is a carboxylate of chromium.

As a further improvement of the invention, the roasting temperature of the precious metal preparation for washing the bowl machine on the silicate substrate is 780-820 ℃.
As a further development of the invention, the precious-metal preparation of the dishwasher-resistant machine also comprises auxiliaries, which comprise rosin and flexible resins, such as polyamides.
By adopting the technical scheme, the flexible resin is dissolved in the organic metal compound to be used as a carrier, thereby being beneficial to screen printing.
As a further improvement of the invention, the auxiliary agent also comprises an antifoaming agent and a thixotropic agent. By adopting the technical scheme, the screen printing is favorably and better carried out.
The invention also discloses a precious metal decorative film for the dish washing machine, which is obtained by transferring the precious metal preparation of the dish washing machine onto a silicate substrate and roasting at 780-820 ℃.
