Description

[Detailed description of the invention] Industrial field of application The invention is a writing instrument such as a pencil, colored pencil, ballpoint pen, fountain pen, or water-based marker that can be used to write and erase characters and figures easily. Concerning ceramics such as tableware and tiles that have a space for writing notes.

Problems to be solved by conventional techniques and ideas Ceramic glaze forms a glassy coating on the surface of the base material, and the glazed surface is generally hard and smooth, so it cannot be used with pencils, ballpoint pens, etc. Even if you try to write letters or figures with a writing utensil, the tip will slip, and the graphite of a pencil or the ink of a ballpoint pen will hardly stick to the surface, making it impossible to write clearly. On the other hand, with fountain pens and markers, it is possible to write with liquid ink that adheres to the smooth glossy glaze, but since it is only attached to the surface, if the ink is water-based, it is possible to write on it after it has dried. Even after that, it can be erased by simply rubbing it lightly with your finger.

Purpose of the invention This invention is capable of clearly writing letters and figures on the surface of tableware such as pots and ceramics such as wall tiles using various writing instruments, and to the extent that they cannot be erased by lightly rubbing them with a finger. To provide ceramics having a memo writing field which can be easily erased by rubbing with an eraser, except when oil-based ink is used.

Structure of the invention As a means to achieve the above purpose, the present invention has the following features:
A memo writing field consisting of a polished surface with fine crystals precipitated was formed on a certain range of the surface of the base material with a glossy glaze by transfer printing.

Function of the invention The invention has the above structure, and the memo writing area has a matte surface formed on a glossy glaze, so there are no large irregularities, and the fine crystals that have broken out are rough and protruding from the flat surface. The graphite of the pencil is scraped off by the protrusions of the crystal and embedded in minute depressions.
In addition, since the ink from fountain pens and markers stays in the minute recesses between the crystals, it is possible to draw letters and shapes clearly using these writing instruments, and the scraped graphite and dried ink are Since the eraser is embedded in the recess, it cannot be easily erased even if you rub it with your fingers. However, when you rub it with an eraser, the eraser itself and its debris enter the fine recess due to elastic deformation and adhere to the graphite and ink. The characters and figures are surely erased by removing them from the recesses. Note that if the adhesive is strong, such as colored pencils or oil-based markers, and cannot be erased sufficiently with an eraser, it may be wiped off with a cloth soaked in water or solvent.

EXAMPLE Hereinafter, an example in which the present invention is applied to a cup will be explained based on the attached drawings.A pattern 3 is formed by transfer baking on the surface of a base material 1 with a handle 2 on which a white glossy glaze is formed. , a part of the picture 3 forms a memo writing field 3a. This memo writing field 3a is generally called pine glaze, and for example, an appropriate amount of metal oxide is added as a coloring pigment to a colorless pine glaze consisting of 30 parts of feldspar, 23 parts of limestone, 17 parts of silica stone, and 30 parts of waxite. It is formed by transferring the pattern 3 onto the surface of the base material 1 using a transfer paper printed on a mount paper and firing it separately from the general glaze that forms the other part 3b. Unlike the other part 3b, fine crystals are precipitated on the surface, resulting in a polished surface that is smooth like the surface of an eggshell, but has countless minute irregularities on the surface, and the graphite of the pencil is formed by the protrusions. It is scraped off and embedded in the recess, and in the same way, ink from markers and fountain pens stays in the recess, making it possible to clearly write letters and figures, and it does not erase easily when rubbed with a finger. It can be quickly erased using an eraser or the like.

Effects of the invention Therefore, in the case of tableware, this invention allows you to write notes on cooking methods or messages to family members in the memo area, or when applied to wall tiles,
You can use the memo writing area as a bulletin board, message board, etc.
When applied to gift ornaments, it can be used as a memo field for writing words of congratulations, etc., and has the effect of significantly expanding the uses of ceramics.
