Penelope Wurr’s handmade pieces are collectibles. The enamels are delicate and should be treated with care.
Washing with mild detergent will not harm your glass, although dishwashers or hard abrasives should not be used. If the design is on the base of your piece care should be taken; use two or three small clear plastic discs to raise it from the display surface.
While every attempt has been made to ensure the life of these enamels some may be affected by continuous exposure to strong sunlight.
The rest is common sense. Your Penelope Wurr glass prefers not being dropped onto hard surfaces. However it does appreciate being displayed, used for flowers, as a container for candy or potpourri, & loves being admired and fussed over. Enjoy!
