The Delphia Art Glass award is a popular award choice for companies with logos that use the cobalt blue or darker green colors. It is sure to impress your recipients. The Delphia Art Glass Award is set on a black crystal base. The text will be silver filled for readability. Art glass awards are hand blown, and each piece will be slightly different in color, shape, and size. Bubbles and swirls are a part of the process and are considered normal and acceptable.
