The present invention relates to a glass plate which is provided with a first main surface, and a second main surface which faces the first main surface. An antiglare portion and a non-antiglare portion are provided to the first main surface. The average lengths (RSm) of elements of roughness curves of the antiglare portion and the non-antiglare portion are respectively 1 μm or higher. The difference between the RSm of the antiglare portion and the RSm of the non-antiglare portion is 100 μm or lower.

A radically polymerizable dental material having at least one radically polymerizable monomer without acid groups, at least one radically polymerizable monomer containing an acid group, at least one fluoroaluminosilicate glass filler and/or radiopaque glass filler, and at least one initiator for the radical polymerization, wherein the filler is an acid-treated fluoroaluminosilicate glass filler and/or radiopaque glass filler.

A method for manufacturing a formed glass includes using a heating apparatus. The heating apparatus includes a heating element and a heat reservoir having a transmittance of 50% or more in a wavelength of 0.5 um to 2.5 um. The heat reservoir is arranged between the heating element and a glass substrate as an object to be heated. The glass substrate is heated with the heating element, and the glass substrate is formed into a desired shape.

An inorganic glass coating agent is composed mainly of an alkoxysilane and silane coupling agent, wherein the alkoxysilane is a trifunctional alkoxysilane, with a flash point of no higher than 40° C. as equivalent to a class I petroleum and/or a class II petroleum, and a molecular weight of 180 or lower, and wherein at least one of the alkoxysilanes is present at 10 wt % to 80 wt %, where the total percentage of the alkoxysilanes and silane coupling agent is 100 wt %. The inorganic glass coating agent exhibits stable drying and hardening properties not only under ordinary conditions but also under poor conditions by selecting an alkoxysilane having a relatively low molecular weight and low flash point, with high reactivity.

A method for producing a glass substrate with through glass vias according to the present invention includes: irradiating a glass substrate (10) with a laser beam to form a modified portion; forming a first conductive portion (20a) on a first principal surface of the glass substrate (10), the first conductive portion (20a) being positioned in correspondence with the modified portion (12); and forming a through hole (14) in the glass substrate (10) after formation of the first conductive portion by etching at least the modified portion (12) using an etchant. This method allows easy handling of a glass substrate during formation of a conductive portion such as a circuit on the glass substrate, and is also capable of forming a through hole in the glass substrate relatively quickly while preventing damage to the conductive portion such as a circuit formed on the glass substrate.

A cooking appliance with a cooktop includes a glass-ceramic substrate with a top surface for receiving cookware thereon for heating. The surface includes a coating formed by applying a sol-gel coating to the surface after the surface is roughened to increase the surface roughness of the top surface and improve adhesion of the coating thereon. The sol-gel coating forms a matte finish on the cooktop while having anti-stick properties for cleanability.
