Monochrome Glazes: High-Fired vs Low-Fired, Core Distinctions
News 2026-07-30 76
What is monochrome glaze?
A monochrome glaze, historically referred to as a “single-color glaze,” is one of the most important branches of color-glazed ceramics. The glaze covering the entire vessel presents a uniform and consistent tone. Its color comes from metal oxides contained in the glaze materials rather than from hand-painted decoration. Variations in glaze composition, firing temperature, and kiln atmosphere can create subtle differences in depth, gloss, texture, and color.
Based on firing methods, monochrome glazes are generally divided into high-temperature and low-temperature varieties. These two categories differ significantly in their production processes, surface textures, durability, chemical stability, and suitable applications. High-temperature glazes are often harder and more stable, while low-temperature glazes can offer brighter colors and a wider range of decorative effects.
Monochrome glaze firing temperature and firing process
| High-temperature | low-temperature | |
| Firing temperature | Above 1250℃ | 700–1050℃ |
| Process | The greenware is glazed and then fired in the kiln in one go. The porcelain body and glaze are simultaneously sintered at high temperature, and the body and glaze are closely integrated as one. | The second firing process (first firing the white porcelain blank at high temperature, then applying a low-temperature glaze and performing a low-temperature re-firing) The glaze is applied to the surface of the already fired porcelain body, just like “putting on a colorful coat” for the porcelain. |

Intuitive comparison of the glaze texture and physical properties
High‑temperature monochrome glazes:
1. High hardness and excellent abrasion resistance – the glaze surface resists scratching even with regular use.
2. Chemically stable against acids and alkalis; does not readily discolor, fade, or lose its sheen over long periods.
3. The color and finish are understated and warm, with a jade-like matte luster; hues appear deep, dense, and substantial.
4. Excellent adhesion between body and glaze, with virtually no risk of delamination or peeling.
5. When properly formulated, high-temperature glazes pose no heavy-metal leaching risk, making them safe for food-contact wares such as teaware and dinnerware.
Low‑temperature monochrome glazes:
1. Relatively lower surface hardness; prone to fine scratches from prolonged friction or abrasive cleaning.
2. Gloss tends to be bright and highly reflective, giving a vivid, mirror-like finish that appears more striking.
3. Lead-based fluxes are commonly used in traditional formulations, reducing long-term stability. Extended exposure to acidic beverages may raise concerns about heavy-metal migration.
4. The glaze layer bonds to the body, but in rare cases, repeated thermal cycling (heating and cooling) can cause minor flaking or peeling.
5. Advantages: a much broader palette of colors, more consistent color development, and easier to fire in large‑scale production.
How to simply distinguish by the naked eye?
1.Gloss
High temperature monochrome glazes: warm, matte or soft luster – jade like in feel.
Low temperature monochrome glazes: bright, glaring, with a strong mirror like reflectivity
2.Functional Use
High temperature monochrome glazes:the overwhelming majority of teaware, teacups, and dinnerware are made with these, for safety and durability. Low temperature monochrome glazes:more commonly found on decorative ornaments, displayvases, and antique style presentation pieces.
3.Historical Standing
High temperature monochrome glazes: have been prized as premier official kiln wares since ancient times.
Low temperature monochrome glazes: have traditionally been used mainly for ornamental and decorative objects.
How to Choose？
• For everyday ceramicware such as teacups, tea sets and dinner plates: Opt for high-fired monochrome glazes. They are safe, durable and resistant to deterioration with long-term use.
• For decorative vases, art ornaments and collectible display pieces: Either high-fired or low-fired monochrome glazes work. Choose based on your aesthetic preferences.
