A testing method of thermal barrier coating (TBC) is for evaluating the presence or absence of damage to TBC formed on a bending part on which compression stress acts. The method includes a test piece that includes a pair of arm parts, a bending part arranged between the pair of arm parts, and a TBC layer on a bending surface of the bending part; attaching the test piece to a compression testing device after preparing the test piece; and applying compression stress to the test piece in a direction for bringing the pair of arm parts close together after attaching the test piece with the compression testing device. The pair of arm parts are arranged so as to separate from each other from base end portions toward front end portions of the arm parts. The bending part is arranged between the base end portions.

Provided is an inorganic composition having excellent mechanical strength and the like.

Disclosed is an inorganic composition and the like, wherein the flexural strength of the inorganic composition is 300 MPa or greater, and the fluorescence intensity based on JIS K 0120, is 3,000 RFU or less.

The present invention is related to a water-resistant shoe and a method of making the water-resistant shoe. In most embodiments the shoe comprises an outsole, an insole, an upper, and a bootie product comprised of a bootie, a bootie liner, a strobel and a gasket. In many embodiments water-resistant materials such as tape or glue are used to cover all seams and joints. In some embodiments the different pieces are tested for water-resistance before combining and in others the final shoe is tested for water-resistance. The present shoe and method provide a comfortable yet water-resistant shoe.
