Pâte-sur-pâte — French technique, meaning 'paste-on-paste', which gained popularity during the late 19th and early 20th centuries. It involves the creation of delicate low-relief decorations by layering white slip onto a contrasting background. This decorative style requires a meticulous process of building up multiple layers of white clay slip to achieve the desired design.

Artisans carefully apply thin layers of white slip onto a base or background of a different colour, allowing each layer to dry before adding the next. By gradually building up the layers, they create intricate designs with a raised, three-dimensional effect. The contrast between the white slip and the underlying background enhances the visibility of the detailed decoration.

Pâte-sur-pâte requires exceptional skill and precision, as it demands a steady hand and a keen eye for detail. Artists often use fine brushes or tools to delicately shape and refine the relief. The result is a beautiful, textured surface with a soft, ethereal quality.
