An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 15 to 50 wt % of phosphorus pentoxide (P.sub.2O.sub.5); 5 to 20 wt % of one or more of lithium oxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF.sub.2), or aluminum fluoride (AlF.sub.3); 1 to 35 wt % of one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO); and 5 to 30 wt % of one or more of manganese dioxide (MnO.sub.2), molybdenum trioxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or nickel oxide (NiO). The enamel composition may be cleaned without being putting it into water.

A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt %, more preferably 0.001-0.010 wt %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-010. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO.sub.2. An embodiment of the invention covers a glass made according to the method.

A method of recycling glass fiber-reinforced polymer composite materials that can provide improved quality recycled glass fiber is described. More particularly, the method comprises pyrolysis of glass fiber-reinforced polymer composite scrap and/or end-of-life material and the subsequent immersion of the pyrolyzed glass fibers in a molten salt bath, e.g., comprising molten potassium nitrate. Immersion in the molten salt bath can eliminate char from the pyrolyzed fibers, as well as removing residual inorganic materials. In addition, immersion in the molten salt bath can strengthen the glass fiber, which can result in the recovery or avoidance of tensile strength losses normally incurred through traditional char removal processes.

Apparatus, system, and method for blending batch and cullet at a predetermined cullet ratio for feeding to a furnace. It includes a first hopper for holding cullet; a second hopper for holding batch; feeder associated with the second hopper; a chamber positioned to receive cullet from the first hopper, an inlet spout configured to receive cullet from the first hopper so that cullet flood feeds into the chamber to keep it constantly filled with cullet up to its angle of repose, and an outlet spout; a chute positioned to receive batch from the feeder and extending into the chamber and having a chute outlet having a diameter equal to or larger than the outlet spout; a charger for receiving mixed batch and cullet from the chamber; and a controller operatively connected to the feeder and to the charger.

A system for producing a stream of glass sand from mixed recyclables comprises first and second pulverizing system, each comprising a size-reducing pulverizer and a size-separating trommel. The pulverizers and trommels are heated, so as to also serve as driers.

A lightweight modified filter material, a preparation method therefor and use thereof, the lightweight modified filter material being prepared from the following components in parts by mass: 75-100 parts of waste glass, 5-20 parts of a metal oxide modifier and 1-10 parts of a foamer. The lightweight modified filter material has the advantages of being lightweight, having large specific surface area, a high isoelectric point, porosity and the like, increasing the isoelectric point and service life of the filter material. The added metal oxide can be combined with SiO2 in the glass to form Si—O-Me (Me metal ions) and enter the glass network.

A method of fining glass is disclosed that includes flowing a molten glass bath through a fining chamber. The molten glass bath has an undercurrent that flows beneath a skimmer that is partially submerged in the molten glass bath. One or more fining agents are introduced into the undercurrent of the molten glass bath directly beneath the skimmer from a dissolvable fining material component. In this way, the fining agent(s) may selectively target the gas bubbles drawn under the skimmer within the undercurrent of the molten glass for removal. The method may be employed to fine molten gas produced in a submerged combustion melter. A fining vessel for fining molten glass is also disclosed that includes a housing, a skimmer, and a dissolvable fining material component disposed directly beneath the skimmer.

As a solid electrolyte used in a lithium ion secondary battery, it has not been possible to obtain a lithium ion conductor precursor glass and a lithium ion conductor in which crystallization progresses at low temperatures and which exhibit high ion conductivity. The present invention can obtain a lithium ion conductor precursor glass and a lithium ion conductor in which crystallization progresses even at low temperatures and which exhibit high ion conductivity by containing 10-35% of a Li.sub.2O component, 20-50% of a P.sub.2O.sub.5 component, greater than 0% to 15% of an Al.sub.2O.sub.3 component, 20-50% of a GeO.sub.2 component and greater than 0% to 15% of a Bi.sub.2O.sub.3 component and/or a TeO.sub.2 component.
