We're big fans of laboratory glass used in the home (see Accessories: Chemistry in the Kitchen).  Portand-based Pigeon Toe Ceramics recently came out with a selection of hand-made porcelain vessels cast from vintage laboratory glass; perfect for spring flowers.

Above L: Filtering Flask with unglazed porcelain exterior and choice of ten interior colors (shown in clear); $28 at Velocity Art and Design. Above R:  Porcelain Cast Volumetric Flask with unglazed porcelain exterior and interior glazed in clear gloss; $28 at Pigeon Toe Ceramics. Both measure 6 inches in height.

Above: The Wall-Mount Test Tube Vase hangs from a nail or screw via a hole on the back of the vase. The tube is 6.75 inches tall; $32 for a single test tube or $84 for a set of three at Branch Home.

Above: The Hanging Test Tube Vase, which comes threaded with a natural leather strap for secure hanging, is 6.75 inches tall; $36 for a single test tube or $96 for a set of three at Branch Home.
