Abstract: This invention is directed to the production of glazes exhibiting an earthenware appearance which are particularly suitable for decorating ceramic dinnerware. The glaze composition consists essentially of about 4-8% by weight SnO.sub.2 and 4-8% by weight TiO.sub.2, the total SnO.sub.2 +TiO.sub.2 being about 10-14%, and about 0.025-0.04% by weight MnO.sub.2 incorporated into a base frit consisting essentially, as analyzed in weight percent on the oxide basis, of about______________________________________ SiO.sub.2 37-49 Al.sub.2 O.sub.3 4-7 B.sub.2 O.sub.3 6.5-11 ZrO.sub.2 0-1.75 Na.sub.2 O 1.75-3.5 K.sub.2 O 0.75-2.5 PbO 21-32 CdO 0-0.75 CaO 1-9 TiO.sub.2 0-0.35 F 0-0.6 ______________________________________The fired glaze contains crystallites of rutile and cassiterite.

Abstract: A microporous filler for dental composite resin restorations has been developed which gives greatly improved finishability, system non-toxicity and x-ray opacification. These fillers are prepared from frits obtained by the low temperature calcination of gelled inorganic "polymers" followed by a pulsed high-heat treatment.

Abstract: A temperature sensitive electrical element and method of making the same comprising the steps of applying to the surface of a substrate and firing a mixture of glass frit and particles of titanium dioxide (TiO.sub.2), and titanium metal. The mixture is fired in a non oxidizing, inert, or reducing atmosphere at a temperature which softens of the glass frit. When cooled, an element is provided with a glass film strongly bonded to the substrate and having dispersed therein conductive particles mainly of titanium oxide (Ti.sub.2 O.sub.3). The element produced can be terminated by the use of electroless plating and provides a substantially linear resistance to temperature characteristic and a relatively high temperature coefficient of resistance.

Abstract: A solder glass suspension for sealing glass or other ceramic parts is provided having the characteristics of a reversible gel, exhibiting high viscosity during storage and after extrusion onto a sealing surface, but relatively low viscosity under shear stress during extrusion. The use of the suspension for sealing glass or ceramic parts is also described.
