摘要:
The invention provides an opalescent forehearth color concentrate comprising a non-smelted agglomerated interspersion of particles for use in coloring glass, said concentrate comprising by weight from about 10% to about 70% of a glass component and from about 30% to about 90% of one or more opalescent pigments, the glass component comprising by weight from about 10% to about 50% ZnO and about 15 to about 60% SiO2. The invention also provides a method of using the color concentrate.

This invention relates to lead free, cadmium free, bismuth free low melting high durability glass and enamel compositions. The compositions comprise silica, zinc, titanium, and boron oxide based glass frits. The resulting compositions can be used to decorate and protect automotive, beverage, architectural, pharmaceutical and other glass substrates.
摘要:
The invention provides an enamel composition that imparts a frosted appearance to glass articles such as bottles and windows while allowing a wide firing range and maintaining consistent properties such as gloss and light transmittance. The composition comprises a zinc borosilicate glass frit with one or more crystalline materials added thereto.

摘要:
The present invention provides a method of making a decorated multilayer glass structure using a single firing step that includes that use of a crystallizing glass enamel composition that contains ingredients to ensure the complete burnout of the organic portion of the composition upon firing and bending of a mated pair of glass sheets. A benefit of the composition is that when applied to one sheet of a mated pair of glass sheets, it burns out completely during firing and bending of the pair. The presence of high levels of oxidizers in the composition ensures a supply of oxygen to enable combustion of the organic vehicle while firing the glass sheets and prior to the sintering of the enamel composition to only one glass sheet in a mated pair of decorated or colored glass sheets.
摘要:
A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.
摘要:
An inlead for an electric lamp formed of an alloy of tungsten and molybdenum. The inlead has a rate of thermal expansion or contraction approximating that of the glass forming the bulb. This minimizes the expansion/contraction mis-match stress between the two materials. In addition, the alloy composition functions to reduce oxidation and degradation of the lead.
摘要:
A method of manufacture for a lamp involves making up, separate from an envelope, a sub-assembly comprising a lead structure and a vitreous body that surrounds it. In one form of this method, particles of vitreous material are pressed into a mold cavity that surrounds the lead structure, thus forming a compact surrounding the lead structure. This compact is sintered in an inert atmosphere, thereby forming the sub-assembly. Thereafter, the sub-assembly is placed in an opening in the envelope, and a hermetic seal is made between the envelope and the vitreous body in the interface region between the envelope and the vitreous body.
