Overglaze decoration, is a technique in which decorations are applied on an unfired glazed surface. During firing, the colors fuse with the glaze, becoming fully integrated and protected by the vitrified layer, ensuring durability and a smooth finish.
This technique allows intricate designs to be created and additional details to be added without altering the base glaze. It is commonly used on decorative ceramics, such as plates, vases and tiles, where fine details are essential to the final design. Unfired overglaze decoration is especially valued for its versatility, allowing a wide range of styles and effects, from fine, precise lines to more organic textures and gradients.
Interesting Fact
This technique has been used for centuries in majolica and earthenware ceramics, particularly in Italy and Spain, to achieve brilliant colors that stand out against white glazes.
Helpful Tip
When applying decoration on unfired glaze, make sure that the glaze surface is completely dry and clean so that the pigments adhere properly.
