CN100450977C - Method of manufacturing starlight glaze - Google Patents

Abstract

The invention discloses a making method of stellar glaze, which comprises the following steps: adopting lithium carbonate, dolomite, quartz flour, calcite, low-temperature fused block, kaolin, silicon limestone and ferric oxide as raw material; using chromium oxide or ferric oxide as coloring oxide; balling through wet method; sieving; allocating slurry with density at 45-65 Baume's degree; fetching smooth ceramic blank to immerse glaze in the kiln; sintering in the oxidizing atmosphere under 1160-1200 deg.c rapidly; obtaining the product.

Description

A kind of making method of starlight glaze

Technical field

The present invention relates to a kind of making method of starlight glaze.

Background technology

In the porcelain industry, the moulding of base substrate is very important at present, but the more apparent prominent position of the allotment of glaze, the blank of same moulding, often because of the different visions to the human consumer of overglaze produce Different Effects, the sort of smooth amorous photo people, the glaze that color can reflect often obtains unusual decorative effect; People like the porcelain beautiful design, but prefer colorful, sparkling and crystal-clear moist and porcelain with strange and new visual effect, this also is a reason of studying glaze in the current porcelain industry energetically.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can in 1160～1200 ℃ of oxidizing atmospheres, burn till starlight overglaze glaze fast.Described starlight glaze under the refractive power state, can send just as stellar scintillation, dazzling brilliant starlight color and this name, the decorative effect of the magnificent wealth and rank of special tool.

The making method of the so-called a kind of starlight glaze of the present invention, it is characterized in that: get the raw materials ready (by weight percentage by following prescription (1), down together): Quilonum Retard 15～25%, rhombspar 10～15%, silica powder 5～10%, calcite 5～8%, low temperature frit 30～40%, kaolin 5～8%, wollastonite 7.5～15%, chromic oxide 0.5～1.5% or ferric oxide 10～15%; Each component percentage composition sum is 100%;

(2) wet ball grinding is 12～16 hours, selected material: ball: water=1: 1.5: 0.5;

(3) glaze behind the ball milling is crossed 200 mesh sieves, and the slurry of furnishing concentration 50～65 degree Beaume promptly again.Get and go into to burn till fast roller kiln after the bright and clean porcelain blank of appearance soaks glaze, under 1160～1200 ℃ oxidizing atmosphere, fire.

The glaze layer thickness that the present invention suits is 0.2～0.4mm.Low temperature frit is commercially available special-purpose frit in of the present invention the getting the raw materials ready, and adopts chromic oxide or ferric oxide as coloring oxide.

Embodiment

Example one: by following formulated starlight glaze (all raw materials are technical grade, weight percent, down with): Quilonum Retard 20%, rhombspar 12.5%, silica powder 8%, calcite 8%, low temperature frit 35%, kaolin 8%, wollastonite 7.5%, chromic oxide 1%; Batching was carried out wet ball grinding 12～16 hours, selected material: ball: water=1: 1.5: 0.5; Glaze behind the ball milling is crossed 200 mesh sieves, and the slurry of furnishing concentration 50～65 degree Beaume promptly gets required glaze again.Get the bright and clean porcelain blank of appearance and soak glaze, control glaze layer thickness goes into to burn till fast roller kiln about 0.3mm, after in 1160～1200 ℃ oxidizing atmosphere, firing, and the stellar scintillation of gained glaze, dazzling brilliant, the impression of giving a kind of magnificent wealth and rank of people, it is unforgettable to look over so as to check.

Example two: by following formulated starlight glaze (all raw materials are technical grade, weight percent, down with): Quilonum Retard 18%, rhombspar 12%, silica powder 7.5%, calcite 6.5%, low temperature frit 32%, kaolin 6.5%, wollastonite 7.5%, ferric oxide 10%; Batching was carried out wet ball grinding 12～16 hours, selected material: ball: water=1: 1.5: 0.5; Glaze behind the ball milling is crossed 200 mesh sieves, and the slurry of furnishing concentration 50～65 degree Beaume promptly gets required glaze again.Get the bright and clean porcelain blank of appearance and soak glaze, control glaze layer thickness goes into to burn till fast roller kiln about 0.3mm, after in 1160～1200 ℃ oxidizing atmosphere, firing, and the stellar scintillation of gained glaze, dazzling brilliant, the impression of giving a kind of magnificent wealth and rank of people, it is unforgettable to look over so as to check.
