Abstract

The invention relates to a preparation method of speckled glaze.According to the preparation method, prepared ground glaze and cover glaze are adopted, ground glaze components start to be subjected to phase splitting at the melting temperature of 1150 DEG C-1180 DEG C in an oxidizing atmosphere by adopting a specific firing system to form a calcium-enriched and iron-poor phase and an iron-enriched and calcium-less phase which contain the different ingredients, then the ground gaze and the upper-layer cover glaze are penetrated each other at the melting temperature of 1250 DEG C-1280 DEG C, and after cooling is performed, the eel back speckled glaze is formed.According to the speckled glaze, the surface is smooth, the background ground glaze and speckles both have the vitreous luster, the lead dissolving-out amount and the cadmium dissolving-out amount in the product are both not detected out, and the speckled glaze can be used for tea tasting tea sets and daily tableware decorates.

Description

technical field [0001] The invention relates to a method for preparing spotted glaze, which belongs to the technical field of ceramic manufacturing. Background technique [0002] In the prior art, there have been introductions about spotted glazes. For example, CN201510037226.3 discloses a erythema crystalline glaze and a ceramic preparation method using the glaze. The glaze is mainly composed of the following raw materials in parts by weight: albite 20- 40 parts, 10-20 parts of quartz, 10-20 parts of calcite, 1-10 parts of calcite, 10-25 parts of ashes, 1-10 parts of glass powder, 5-15 parts of barium carbonate, 5-2 parts of iron oxide; preparation Methods: (1) Weigh the raw materials, wet grind them to get the glaze slurry and then stale; (2) Apply glaze on the biscuit body and carry out drying treatment; (3) Put the dried body in a kiln and fire it in 230-655 minutes Complete the entire firing process of heating-high-temperature heat preservation-cooling-low temperature ...
