Handmade earthenware bowl with reactive glaze. Mid to late 20th century, circa 1960–1990. This bowl is a piece of artisanal earthenware possibly from the 20th century. The style of the glaze, with its reactive glaze and organic patterns, is characteristic of the studio ceramics movement that emerged in the 1950s and 1960s and has remained popular to this day. 

This movement emphasized unique handmade pieces with experimental glazes and textures, often influenced by natural forms and abstract art. The rough, irregular exterior and the lively speckled interior suggest an artisanal approach in which the hand of the maker is clearly visible. 

The specific colors and the way the glaze bleeds or crystallizes in the center point to a technique known as reactive glazing, in which various chemicals in the glaze react during the firing process to create unpredictable and unique effects. This item was produced worldwide by individual potters or small studios.
