Kevin O'Grady is one of the world's borosilicate masters, and has been working glass since many of the younger glass studs were in diapers, one of the earliest pioneers in the use of borosilicate glass. He has pioneered SO many techniques with boro over the years, paving the way for a generation of lampworkers to follow. The glass he creates is truly astounding, and he is most well known for his murrine work, his fuming technique, and his vortex marbles.

Kevin is widely considered the 'Father of the Vortex', as he was the first one to perfect it and successfully market this type of marble back in the early days of borosilicate glass. He hand mixes most of the colors you see on the backs of his vortexes, and some of the colors inside as well.
