A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.

Provided are a quartz glass crucible capable of withstanding a single crystal pull-up step undertaken for a very long period of time, such as multi-pulling, and a manufacturing method thereof.

A quartz glass crucible 1 includes: a cylindrical crucible body 10 which has a bottom and is made of quartz glass; and crystallization-accelerator-containing coating films 13A and 13B which are formed on surfaces of the crucible body 10 so as to cause crystallization-accelerator-enriched layers to be formed in the vicinity of the surfaces of the crucible body 10 by heating during a step of pulling up a silicon single crystal by a Czochralski method.

A method of manufacturing a solar heat collection pipe includes an inner circumferential film forming step of forming an antireflection film on an inner surface of a glass pipe and an outer circumferential film forming step of forming an antireflection film on an outer surface of the glass pipe. These film forming steps are performed so that a part of a coating film through which a coating material is flowed when the coating material is discharged from the glass pipe in a coating material discharging step of the inner circumferential film forming step and a part of a coating film with which the coating material is in contact when the glass pipe is lifted from the coating material in a lifting step of the outer circumferential film forming step are positioned within a half circumference of the glass pipe in a circumferential direction of the glass pipe.

Disclosed are methods for coating or decorating a surface of a glass sleeve. The methods include depositing a metal layer onto a surface of the glass sleeve by an electroless plating method. Also disclosed are glass sleeves which are coated or decorated on an internal surface, and electronic devices comprising the coated glass sleeves.

The invention relates to a container (1) made of glass or stoneware for a beverage having surface irregularities in a chosen region, the irregularities forming nucleation sites inside the container, the nucleation sites favouring the formation of bubbles in contact with a carbonated beverage, comprising a layer of enamel (10) coating the chosen region, a plurality of enamel grains (12) arranged on the surface of said layer of enamel (10) and attached to said layer of enamel (10), and a hydrophobic compound (13) arranged on a portion of the surface of said enamel grains (12).

A quartz glass crucible 1 having a cylindrical side wall portion 10a, a bottom portion 10b, and a corner portion 10c includes a transparent layer 11 as an innermost layer made of quartz glass, a semi-molten layer 13 as an outermost layer made of raw material silica powder solidified in a semi-molten state, and a bubble layer 12 made of quartz glass interposed therebetween. An infrared transmissivity of the corner portion 10c in a state where the semi-molten layer 13 is removed is 25 to 51%, the infrared transmissivity of the corner portion 10c in the state where the semi-molten layer 13 is removed is lower than an infrared transmissivity of the side wall portion 10a, and the infrared transmissivity of the side wall portion 10a in the state where the semi-molten layer 13 is removed is lower than an infrared transmissivity of the bottom portion 10b.
