Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing wax silver cloisonné ware having a unique strong shine using silver foil.

Wax silver cloisonné is manufactured by adding a step of attaching silver foil cut into a desired shape during several pongee coating steps in the normal cloisonné manufacturing process.

The method for cutting and attaching this silver foil is to do it all by hand, or to glue the silver foil onto a mount using adhesive.
A method is known in which this is cut into a desired shape by photoetching, placed several times on a cloisonné material surface together with a mount, and then the adhesive is dissolved using an appropriate solvent and the mount is removed.

The former method cannot express minute shapes, and the latter method requires complicated work and tends to cause misalignment when silver foil is attached. The present invention has been made in order to improve these inconveniences, and involves directly attaching silver foil to a cloisonné material surface and forming it into a desired shape using a photographic etching method.

That is, in the process of cutting and attaching silver foil, the present invention applies varnish to the cloisonné material surface, adheres silver foil on which many small holes with a diameter of 0.2 or less are formed, and then This is a method for producing wax silver cloisonné, which is characterized by wiping off varnish from the surface of the silver foil, and then forming the silver foil into a desired shape using a photoetching method.

To form small holes in silver foil, it is best to hit the silver foil with a horizontal copper brush.

When adhering the silver foil, this small hole varnish flows out to the surface, so the silver foil can easily adhere to the cloisonne base surface without flowing sideways. At this time, even if the surface of the substrate is uneven, the silver foil will stretch to some extent, so this work is easy. In addition, this small hole can be seen through the surface after completion,
If it is sufficiently thick, that is, if the diameter is about 0.2 skin or less, it will not be visible to the naked eye and will not cause any aesthetic problems. To wipe off the varnish, it is effective to use cotton soaked in a solvent such as methanol.

For the photographic corrosion method, a known method can be used as is; a photosensitive solution is applied onto the surface of the silver foil, a master plate with the desired shape is layered, exposed and developed, and unnecessary parts of the silver foil are melted using a solution such as ferric nitrate. Let it come out. Note that if a point light source is used during exposure, a detailed figure can be correctly exposed even if the original plate is somewhat separated from the surface due to irregularities on the substrate surface. After the above work, apply yuzu medicine and attach it in the same way as regular cloisonné.

At this time, the remaining varnish and photosensitizer are removed due to the high temperature, and no stains or the like will be produced on the final product. As described above, the manufacturing method of the present invention is simpler than the conventional method using photographic etching because the silver foil is directly attached to the cloisonné base surface, and there is no possibility of misalignment.

Moreover, since the method of the present invention does not require the work of layering the cut silver foil on the base surface, it is possible to express more detailed figures than the method using the conventional photographic etching method. Next, Examples will be shown to further specifically explain the present invention.

Example First, prepare the cloisonne base.

This is manufactured by molding a pure steel plate, washing it with dilute sulfuric acid, applying pongee to the front and back, and baking it in an electric furnace.The surface is then coated with colored sleeves and baked twice. Next, varnish is applied to the surface of this cloisonne material, and silver foil with many small holes is adhered and bonded by hitting it with a yellow steel brush.

Next, use cotton containing methanol to wipe off the varnish that has spilled onto the surface of the silver foil.

Apply a photosensitive liquid (TPR20 manufactured by Tokyo Ohka Kogyo Co., Ltd.) to this surface.
Apply 1).

A transparent vinyl film with a desired shape drawn in ink is placed on top of this, and exposed using a point light source to create a phenomenon. Next, it is immersed in a ferric nitrate solution to lacquer out the unnecessary parts of the silver foil. Next, colored pongee is applied to the surface and baked to complete the work.
