Glass Act Salt and Pepper Shakers are created by artisans who have been producing them since the 1970's in central California. Each piece of glass is individually crafted using a technique called lampworking. The artist works the glass over a small flame of intense heat, adding color and shaping the piece to the desired form. Their salt and pepper shakers encompass a unique range of designs, both whimsical and pretty, yet are also very durable, made of Pyrex glass with non-corrosive chrome lids.
