Production process

Mark Hill has written an excellent article, dated 8 December 2010, on Timothy Harris's Graal on Judith Miller's Antiques & Collectables web site (requires free registration for access).


All the examples of graal are one-off, unique pieces in a great diversity of designs. We do not intend to display many examples here.

Jonathan Harris

Experimental graal vase, made 1989

Designed, made, and dated by Jonathan Harris, in 1989. This rare experimental piece was formerly kept in the 'museum cabinet' at the Isle of Wight Studio Glass premises until liquidation meant it had to be sold. The vase sits on a clear glass footed base and measures 9 cm x 9 cm. On the base is 'Isle of Wight Glass - '89' inscribed by hand by Jonathan.

A flattened baluster vase in dark purple over pink glass, 12 cm maximum width x 8 cm high, made about 1992. It is signed "Jonathan Harris Isle of Wight Glass England 'Graal'." Around the time this piece was made, Jonathan Harris comments "I was still experimenting with powder enamel colours on the outside of the graal embryo before being picked up, blown into shape & finally sprayed with solution of stannous chloride, which is where the slightly mat surface lustre & iridescence comes from."
