Abstract

The invention discloses a making method of ice-crystal glaze, which comprises the following steps: adopting zinc oxide, lithium carbonate, titanium oxide, calcite, transparent fused block, kaolin, quartz flour and copper oxide as raw material with copper 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 with glitter surface.

Description

A kind of method of manufacturing ice-crystal glaze

Technical field

The present invention relates to a kind of preparation method of ice crystal glaze.

Background technology

In the porcelain industry, it is very important that base substrate is made moulding, the allotment of glaze more can demonstrate the attractive in appearance of product, the base substrate of same moulding, often produce Different Effects because of the different visions of overglaze to the human consumer, the sort of sparkling and crystal-clear moist and strange and new visual effect, exquisite perfection of more apparent product and fashion.

Summary of the invention

The objective of the invention is to prepare and a kind ofly can in 1180-1200 ℃ oxidizing atmosphere, burn till ice crystal overglaze glaze fast, described ice crystal glaze is to gain the name to form a kind of similar frost flower shape crystallization material in the glaze, ice crystal glaze crystallization is greatly brilliant and spread all over whole glaze and unusual, and its crystalline substance spends big diameter can reach 10mm.Just as pure white crystalline frost flower, frost flower flicker has sparkling and crystal-clear glossyly so-called ice crystal glaze, gives the people a kind of pure and noble, the sense of pretty ease elegance under irradiate light.

A kind of method of manufacturing ice-crystal glaze is characterized in that: get the raw materials ready by following prescription (1): zinc oxide 15～20%, Quilonum Retard 8～15%, titanium oxide 8～13%, calcite 15～20%, clear frit 5～8%, kaolin 13～20%, silica powder 20～35%, cupric oxide 0.1～1.5%; Each component percentage composition sum is 100%; Clear frit in getting the raw materials ready is commercially available dedicated transparent frit, adopts cupric oxide as coloring oxide.

(2) wet ball grinding 12-14 hour, selected material: ball: water=1: 1.5: 0.6;

(3) glaze behind the ball milling is crossed 200 mesh sieves, again the slurry of furnishing concentration 45～65 degree Beaume;

(4) get the bright and clean porcelain base substrate of appearance and soak glaze and go into to burn till fast roller kiln, under 1180～1200 ℃ oxidizing atmosphere, fire.

That is to say that the ice crystal glaze is immersed in the present invention on bright and clean porcelain base substrate goods top layer, glaze layer thickness 0.2-0.4mm burns till by burning till roller kiln fast; Gained finished product porcelain surface glaze layer has frost flower shape decorative effect.

Embodiment

By following formulated ice crystal glaze (described raw material all is a technical grade): zinc oxide 17%, Quilonum Retard 10%, titanium oxide 9%, calcite 16%, clear frit 6%, kaolin 16%, silica powder 25%, cupric oxide 1%; Carried out selected material: ball: water=1: 1.5: 0.6 wet ball grinding 12-14 hour; Glaze behind the ball milling is crossed 200 mesh sieves, again the slurry of furnishing concentration 45～65 degree Beaume; Get the bright and clean porcelain base substrate of appearance and soak glaze and go into to burn till fast roller kiln, under the oxidizing atmospheres of 1180～1200 degree, fire and form.The flicker of gained glaze frost flower, sparkling and crystal-clear glossy, give a kind of pure and noble sense of people.

Claims (1)

1, the making method of ice crystal glaze is characterized in that:
