The Wolfard Flower Bulb is an oil lamp with an elegantly simple design. Each are hand-blown from borosilicate glass (known for its strength and clarity) using an exclusive "in-flame" glassblowing technique, which requires a higher degree of skill than other art glass methods. You can use it as an oil lamp or even as a simple bud vase. All are beautifully hand-crafted and designed to be treasured for generations.
