Are these pieces marked with maker stamps?

Many items feature impressed factory marks, painted monograms, or paper labels on the underside that identify the pottery and sometimes the specific artist. Examining the base is standard practice for confirming origin and dating. Some early or miniature items may bear only simple incised initials or faint stamps. Reference books and pottery guides help decode these historical markings.

Can these vases hold water?

While many ceramic and porcelain vases remain functional, older earthenware and stoneware pieces can develop hairline fractures or porous spots over time. It is wise to inspect the interior for leaks before filling decorative vessels with water. Using a small glass or plastic liner inside antique vases protects the historical body from moisture damage and mineral deposits. This precaution preserves the interior glaze and prevents staining.

How do I distinguish Art Nouveau from Art Deco pieces?

Art Nouveau items, produced roughly from the late nineteenth century to 1910, feature organic, fluid lines inspired by natural forms like flowers and vines. Look for whiplash curves and stylised botanical motifs. Art Deco items, emerging strongly into the 1920s and 1930s, embrace geometric symmetry, angular patterns, and stylised modern motifs. The transition from flowing floral designs to structured geometric forms marks the shift between these two styles.
