Most studio glassmakers are, by definition, market driven. It is impossible to survive, as a maker or as a dealer, without catering to market forces and the buying public's taste.
Irridised glass has a very wide appeal. Glass makers all over the world draw their inspiration from a wide range of sources, including Tiffany and Loetz as well as the irridescence found in Roman glass.
People tend to forget that Peter Layton , Siddy Langley, and Norman Stuart Clarke in the UK as well as Jack Ink, in Austria, and Lundberg as well as Orient and Flume in the US, among others, all used to do irridised work. This is not by no means an exhaustive list!
Irridised glass is a genre. My friend, Anthony Stern, once coined the phrase: "Irridised sells"!
At many stages of my career I have wondered whether I should invest in some stannous chloride. Looking back, it was probably a mistake not to have done so!
