Baking temperature is about 900 ℃
In the following, for example, translucent crystallized glass is a low expansion material having a linear expansion coefficient of −3 to −5 × 10 −7 / ° C., and is a film-forming material of a type composed of a vitreous flux and ceramic paint. In the case where the coating is applied, gloss is generated by welding and the decorative effect is high, but cracks occur on the coating surface, which is not suitable for practical use. In the case of no welding, the formed coating film has no cracks, but its surface is uneven, is not dense, has no gloss, etc., so it can be applied only to limited uses in terms of design and function. There wasn't.

Raster paste SL-900X-3 was applied by printing onto the back surface (inner surface) of the flat plate of 50 × 350 mm, which was not the used surface, to form a baking coating at 830 ° C. As a result, a flat plate having the properties shown in Table 1 was obtained. It has a quaint texture when used for the top plate of an electromagnetic cooker, and since the coating is a smooth and dense surface, vapor etc. may adhere,
There was no problem after the adhesive was attached.
Further, the formation of the coating is not practically used due to severe wear, and is therefore suitable for practical use.
