Description

Frost crystal glaze and preparation method thereof

Technical Field

The invention relates to a frost crystal glaze and a preparation method thereof.

Background

At present, the crystalline glaze in the prior art mainly comprises annular crystals radiating outwards from the center, and has a single decorative effect.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a frost crystal glaze, the crystal of which has the effect of forming stripe-shaped scattered radiation from a central crystal nucleus to the outside and greatly improves the decorative effect of the prior glaze.

The technical scheme for solving the technical problem of the invention is as follows: a glaze used for the crystal glaze of frost comprises the following components in parts by mass:

quartz: 20 parts of (1); calcite: 7 parts; zinc oxide: 15 parts of (1); spodumene: 10 parts of (A); titanium dioxide: 10 parts of (A); boundary plate mud: 10 parts of (A); bone charcoal: 18 parts of a mixture; high boron frit: 10 parts of (A); cobalt oxide: 2 parts of (1); copper oxide: and 2 parts.

The invention also provides a preparation method of the frost crystal glaze, which is characterized by comprising the following steps:

preparing the components according to the mass parts of the components;

ball milling is carried out after material preparation;

sieving the ball-milled material;

sieving the materials to prepare glaze slurry;

taking a clean blank, and glazing the blank by adopting glaze slip;

the glazed blank is fired in a kiln at 1230 ℃, and the heat preservation time is required to be more than 45 minutes in the firing process.

After the technical scheme is adopted, the invention adopts a basic saturated flux mechanism of silicon zinc crystallization, and spodumene is added in the middle to form a low-viscosity solution, so that the growth and precipitation of crystals are more facilitated, meanwhile, the addition of the crystallization nucleus formed by titanium dioxide and zinc oxide can ensure that the stability of crystallization is kept without additional manual addition of the crystallization nucleus, and the mode that the crystallization nucleus is independently formed and grows in a single-layer glaze layer is adopted, so that the process operation of manual decoration is reduced, and the large-scale production is more facilitated.
