Can I use these vases for fresh flowers?

Most antique tin glazed earthenware vessels are best kept dry due to the porous nature of the underlying clay body. Water seepage through historical glaze fractures can cause staining or weaken the ceramic structure over time. Display them empty or utilise a discreet, watertight interior vessel if holding botanical arrangements. This protects the historic fabric from moisture damage.

What is the difference between delft and majolica?

Delft generally refers to tin-glazed earthenware made in the Netherlands, traditionally known for blue and white or polychrome maritime and floral designs. Majolica is the traditional term for Italian tin-glazed pottery noted for rich Renaissance polychromy. Both employ similar fundamental techniques of earthenware bodies and tin opacified glazes. Regional painting styles and palette preferences distinguish their origins.

How can I date a tin glazed earthenware vase?

Dating relies on examining the characteristics of the earthenware body, glaze opacity, and stylistic painting conventions. Eighteenth-century pieces often display thinner potting and specific pigment tones, while nineteenth-century revival items show different kiln support marks and standardised forms. Factory marks, where present, help pinpoint specific workshops and production decades. Comparing decorative motifs with established historical examples provides further chronological context.
