Artist Description by Mike Shelbo:
"This exquisite Revolution 33 graduate is the opalescent yellow I have waited for.
Singular Passion will go from transparent to opalescent or milky in colour, but stays in the golden and white-ish yellow range of colour. The result is gorgeous. I tend to like the results of Singular Passion best after a sculpture, either hollow or solid, has been worked in the flame for an hour or longer.
Kiln striking at 1050 F or higher will shift the colour when its is allowed to soak for a duration of time" - Mike Shelbo
