Abstract: Described herein is coated article comprising: (a) a substrate comprising a ceramic, a glass, or a glass ceramic, wherein the substrate comprises a surface, the surface comprising a continuous upper portion and a plurality of lower portions, wherein each lower portion is connected to the upper portion by at least one sidewall; and (b) a first layer comprising a material capable of physical vapor deposition, wherein the first layer is disposed on the continuous upper portion and at least a portion of each sidewall and wherein at least a portion of each lower portion is free of the first layer. Methods of making such coated articles are described herein, wherein the substrate is coating via angular physical vapor deposition.

Abstract: A headjoint stopper for the headjoint of a flute includes a concave bottom disc member having an externally threaded stem axially extending from the back side, a deformable, ring-like sealing member positioned against the back side of the bottom disc, a clamping washing and a hex nut threadedly received on the externally threaded stem. The bottom disc member has an external configuration sized to fit the inside of the headjoint with metal-to-metal contact around the entire circumference of the bottom disc member. The externally threaded stem is integral with the bottom disc such that as the hex nut is advanced along the stem toward the bottom disc, the clamping washer is forced against the sealing member and the sealing member is thereby compressed between the bottom disc and the clamping washer.
