Underglaze cobalt blue

Definition

Underglaze cobalt blue is a specific technique used in pottery and ceramics where a blue pigment made from cobalt oxide is applied to the surface of the pottery before glazing. This method allows for vibrant and durable color that becomes part of the porcelain itself after firing, ensuring that it does not fade or wear away. This technique was particularly significant in the creation of white porcelain during a specific period, enhancing its aesthetic appeal and demonstrating the technical skill of artisans.

Review Questions

• How did the use of underglaze cobalt blue impact the artistic style of Joseon porcelain?
  • The use of underglaze cobalt blue significantly impacted the artistic style of Joseon porcelain by allowing artisans to create vibrant designs directly on the white surface. This technique not only enhanced the visual appeal but also enabled more intricate and detailed work without fear of color fading during firing. The resulting pieces reflected a unique blend of artistry and craftsmanship that defined this period in Korean ceramic history.
• In what ways does underglaze cobalt blue differ from overglaze techniques in terms of application and durability?
  • Underglaze cobalt blue differs from overglaze techniques primarily in its application process and durability. Underglaze is applied before the final glazing process, meaning it becomes part of the ceramic body after firing. In contrast, overglaze is painted on top of the glaze and can be prone to chipping or fading. This makes underglaze cobalt blue more durable and vibrant over time, ensuring that designs remain intact through use.
• Evaluate the role of underglaze cobalt blue within the context of ceramic evolution during the Joseon Dynasty and its influence on modern ceramics.
