Core Knowledge Of Ceramic Cup Colored Glaze

1.Basic color scheme

Ceramic glazes cover eight classic color schemes, including :

white glaze (presented when iron content is less than 0.75%) ,

blue glaze (iron content of 1% -2.5%) 

green glaze (with copper as a coloring agent) ,

red glaze (fired by copper based high-temperature reduction flame) , etc.

Different metal oxides achieve color tone changes through temperature regulation.

2.Process type

Monochrome glaze: uniformly colored throughout, such as traditional glaze colors like sacrificial red and sky blue;

Flower glaze: formed by kiln transformation or composite formula to achieve multi-color blending effect, such as Jun kiln glaze ;

Transparent glaze and colored glaze: Transparent glaze relies on the color development of the body (such as white porcelain), while colored glaze directly presents the Sprayed Two Color Ceramic Mug With Logo.

1.Raw materials and formulas

Glaze is based on minerals such as feldspar, quartz, and kaolin, with the addition of metal oxide coloring agents such as cobalt blue, copper red, and iron blue. It is then fired at high temperatures (1200-1300 ℃) or medium to low temperatures (about 1000 ℃) to form a glassy layer.

2.Firing technology

High temperature glaze: For example, celadon requires firing at 1250 ℃ or above, with strong stability and high safety;

Low temperature glaze: Lead containing solubilizers can lower the melting point, but caution should be taken to avoid the risk of heavy metal precipitation.

1.Heavy metal risk

Some chemical glazes contain elements such as lead and cadmium, and long-term exposure to acidic liquids may cause dissolution. Therefore, it is preferred to use high-temperature fired (>1200 ℃) wood ash glazes or mineral glazes.

2.Purchase suggestions

Prioritize choosing underglaze or full body Ceramic Tea Cup And Saucer Set to avoid direct contact between underglaze colors and beverages;
Check the quality inspection report to ensure that the migration of lead and cadmium meets the national standard

1.Traditional craftsmanship

Grass and wood gray glaze has been passed down for thousands of years, such as the Song Dynasty celadon, which presents a "blue sky after rain" effect through iron element temperature control; Modern innovative glaze colors such as sapphire blue glaze and Chinese red glaze blend traditional formulas with fashionable aesthetics.

2.Decorative Techniques

Color glaze can achieve gradient or texture effects through processes such as immersion glaze and blowing glaze. For example, green glaze cups use carving techniques to enhance their three-dimensional sense.

1.White glazed cup: transparent glaze covers the high white porcelain body, highlighting the purity of the body;

2.Green glazed cup: imitating the style of Song Longquan kiln, with a jade like glaze surface;

3.Red glazed cup: Offering red glaze symbolizes nobility and requires precise control of kiln temperature to avoid color differences.

Note: Modern color glaze technology has achieved over 90% color coverage, but traditional mineral glazes are still highly regarded for their natural coloration and low toxicity. Consumers can choose the matching glaze color type and craftsmanship based on the usage scenario (such as tea sets, coffee cups).
