I love the © Baby Head Cup “Ghost Cup“! I had a unique opportunity to acquire some glow in the dark glass made by the innumerable James Nowak. As he was closing his shop and selling it off all of his equipment I was able to procure a reasonable amount of this glass. James was a very clever artist, with a career in nuclear engineering before pursuing glass. He took the time to produce a sizable amount of glow in the dark frit by mixing photoluminescent pigment in with glass in a variety of colors. It is from this hand crafted batch of glass that the Ghost Cup is produced. This is ultimately limited item, still in production as long as my supply of glowing glass frit holds out.
