A glass sheet has one surface and the other surface facing the one surface in a thickness direction, wherein a fluorine concentration (average fluorine concentration by SIMS at a depth of 1 to 24 &#x3bc;m) in the one surface is higher than that in the other surface. The following expression is satisfied: 0.07&#x2266;&#x394;F/&#x394;HO. &#x394;F (mol %) is a value obtained by subtracting an average fluorine concentration in the surface having the lower fluorine concentration from that in the surface having the higher fluorine concentration, and &#x394;HO (mol %) is an absolute value of a value obtained by subtracting an average HO concentration in the surface having the higher fluorine concentration from that in the surface having the lower fluorine concentration.

The present invention relates to a float glass plate that is formed by continuously supplying a molten glass onto a molten metal in a bath and allowing the molten glass to flow on the molten metal, wherein the float glass plate satisfies the following expression (1) when, on a coordinate axis that is parallel to a through-thickness direction and has, as an origin, an arbitrary point on a principal surface which is positioned on the molten metal side in the bath among both principal surfaces of the float glass plate, a water concentration in glass at a coordinate x (&#x3bc;m) indicating a distance from the origin is represented by C(x) (mass ppm), the thickness of the float glass plate is represented by D (&#x3bc;m), a maximum value of the C(x) is represented by Ca (mass ppm), and a coordinate at which the C(x) is maximum is represented by Da (&#x3bc;m). 

Float glass plate and method of manufacturing thereof

To provide a process for producing granules, wherein a component in an exhaust gas discharged from a glass melting furnace can be reused as a raw material for alkali-free glass, and a heating and drying step is not required for the reuse. Exhaust gas G1 formed in a process for melting a raw material of glass containing a boron component is brought in contact with contacting liquids L1 and L2 to obtain treated liquids S1, S2 and S3 having the boron component in the exhaust gas G1 dissolved therein; magnesium hydroxide is added to the mixture of the treated liquids in a treated liquid tankto obtain a liquid containing a boron component and a magnesium component; by using the liquid, a granulation liquid is prepared; and in the presence of the granulation liquid, a raw material mixture for producing alkali-free borosilicate glass is granulated to produce granules.

An astral lamp includes a light source and a concave mirror. The concave mirror reflects light emitted by the light source and condenses the reflected light on a light source side toward an illumination area remote from the light source. The concave mirror is constituted by a plurality of concave mirror surfaces that form one parabolic mirror of revolution as a whole. The mirror surfaces respectively have curved surfaces for separately reflecting the light emitted by the light source and condensing the reflected light toward an entire portion of the illumination area.
