Cobalt Blue in Ceramics: History, Meaning, and Use in Contemporary Craft

Cobalt blue is undoubtedly one of the most emblematic colors in the history of ceramics. From Tang and Ming dynasty China, through Islamic art, to Spanish and Portuguese ceramics, this pigment has transcended cultures, styles, and eras. Today, it remains one of the most sought-after shades in both industrial ceramics and contemporary craftsmanship.

🌍 Historical origins of cobalt blue

Cobalt pigment was already used in Persia in the 9th century, quickly spreading along the Silk Road. Its intensity and durability made it perfect for decorating ceramics that, centuries later, arrived in Europe as luxury items.

In Spain and Portugal, cobalt blue became the star of tiles and majolica, conveying stories, religious scenes, and geometric patterns that today are part of the cultural heritage.

🎨 Unique properties of the pigment

Cobalt oxide is highly resistant to the high temperatures of the ceramic kiln, ensuring that its color remains vibrant and deep after firing.
Among its main qualities are:

• Thermal stability: maintains its color across different firing ranges.

• Versatility: applicable in glazes, slips, and under or overglaze decorations.

• Chromatic intensity: a deep and vibrant blue that symbolizes purity, spirituality, and eternity.
