Are these vases watertight for flowers?

Many stoneware and fully glazed ceramic pieces can hold water safely for short periods. However, older earthenware and pieces with extensive crazing may allow moisture to seep through the body. It is safest to use a small glass or plastic liner inside historic vases to protect the ceramic fabric from water damage and mineral deposits.

How do I identify the maker of a piece?

Turn the vessel over to examine the base for impressed stamps, painted monograms, or paper labels. Different potteries utilised distinct systems of marks and numbering that changed across the decades. Stylistic clues such as specific glaze palettes or tube lined motifs can also point toward particular workshops or named artists when marks are faded.

What is the difference between earthenware and stoneware?

Earthenware is fired at lower temperatures, resulting in a porous body that requires glaze to hold liquids. It allows for bright, earthy colour palettes typical of Victorian and Edwardian studio pottery. Stoneware is fired much hotter until the clay vitrifies into a dense, stone like material that is naturally impermeable. This makes stoneware heavier and more durable than earthenware.
