What is delft ceramic?

Delft ceramic is a type of tin-glazed earthenware originating in the Netherlands, known for its opaque white surface and painted decoration. Artisans traditionally used cobalt blue pigments to create intricate botanical and figural scenes. Over subsequent centuries, production spread across Europe, incorporating polychrome colours and various revival styles while retaining the core tin-glaze technique.

Are these vases waterproof?

Most antique tin-glazed earthenware vases are porous and prone to moisture seepage through hairline cracks in the glaze. Using them with dry floral arrangements or placing a hidden glass liner inside protects the ceramic body. Careful handling ensures these historic vessels remain preserved for display without risking damage to the original glaze.

How are old vases dated?

Dating relies on stylistic clues, including the profile of the vessel, the composition of the tin glaze, and the pigment characteristics. Seventeenth-century pieces often display specific Chinoiserie interpretations, whereas nineteenth-century revivals exhibit different potting weights and glaze formulations. Comparing painted motifs and factory marks provides further context for placing a piece within a specific century.

How should I clean them?

Dusting with a soft, dry cloth is the safest method for maintaining tin-glazed surfaces. Moisture can infiltrate historic earthenware through existing chips or crazing, so abrasive cleaners and immersion in water are unsuitable. Gentle maintenance preserves the integrity of the fragile glaze and the painted decoration underneath.
