His first studio was established at Praze an Beeble near Camborne, where he set up his kilns, demonstrated his work on open days and exhibited his beautifully blown and coloured art glass. The beautiful effects he was able to achieve reminded of Tiffany and beyond into creations avidly collected by aficionados of handmade-blown glass, vases, bowls, paperweights and sculptures. By the 1990s Clark moved his studio to nearby St Erth, turning out an impressive volume of work, and taking student-apprentices.
He was always generous in his willingness to display the techniques he employed, and also in his gifts to charitable auctions and sales of work. Norman left Cornwall in 2004 to live and work in France, and since that time has moved again, the latest notice being Romania.
