Royal College of Art, Keith.
Where, back in '67, while Michael Harris was tutor in Industrial Glass, Sam Herman came over to give a lecture about the "new" form of glass, the recipe for which had been invented by Dominic Labino, which mean that small quantities of glass could be melted in a small kiln, rather than requiring the huge industrial sized pots used by big industry.
This meant that, for the first time, artists could get their paws on hot glass in a studio setting, and the Studio Glass Movement was born in America.
Sam stayed on and hot glass facilities were set up at the RCA, bringing the Studio Glass Movement to the uk.
Michael Harris was incredibly inspired by all this, and went off to Malta to start Mdina glass, Sam took over at the RCA, and from his work with the students there, "The Glass House" was born - a small shop/studio, where the burgeoning new studio glass artists sold their work.
That's roughly it, in a nutshell.
