How do I date a delft vase?

Dating relies on stylistic shifts, changes in the tin glaze composition, and the specific painting palette used on the earthenware body. Seventeenth and eighteenth-century pieces often display distinct potting weights and pigment tones compared to later nineteenth-century revivals. Examining the foot rim and the interior unglazed surfaces provides further clues regarding the manufacturing period. Comparing known forms and motifs helps narrow down the decade of creation.

Are these vases waterproof?

Most historic tin-glazed earthenware vessels are porous because the earthenware body and glaze can develop microscopic crazing over centuries. Using them to hold fresh water directly is generally discouraged to protect the ceramic fabric. Displaying them as dry decorative objects or placing a hidden liner inside helps preserve the glaze. This protects the historic material from moisture damage.

What is the difference between delft and majolica?

Both utilise tin-glazed earthenware, but delft specifically references Dutch or English production with its focus on blue and white or Chinoiserie styles. Majolica more commonly describes Italian tin-glazed pottery featuring vibrant polychrome palettes. Revival pieces from later centuries sometimes blend these aesthetic traditions, combining Italian forms with delft-style painting techniques.

How should I clean a tin-glazed vase?

Cleaning requires only a soft, dry cloth to remove surface dust without risking the historic glaze or painted cobalt decoration. Harsh cleaning agents or submerging the porous earthenware in water must be avoided. Professional restoration advice should be sought if deeper cleaning is required on fragile or previously repaired areas. Gentle handling ensures the delicate tin glaze remains intact.
