I consulted Bill Gudenrath (CMoG Studio) who replied:
"The best think I've seen on what is in the commercially available 'liquid gold' products is "Gold in the Pottery Industry" by L. B. Hunt in Gold Bulletin, v. 12, no. 3, 1979, pp. 116-127.
I didn't find a copy of this article in our library. You should be able to obtain one via Interlibrary Loan at your local library.
You may find additional information in these sources: Try contacting the suppliers listed to find information about a gold enamels and firing temperatures for blown glass pieces (Paradise Paints is closed).
Glass on Metal Magazine provides extensive online information about enamels: http://www.glass-on-metal.com/links/web-resources.htm
They also have a message board where you could ask for formulations:
"Proper use of Liquid Metals" by Martin Hanson provides technical information about firing on enamels (or glass)
This article, found in their back issues, describes the preparation of enamels:
Information in this article about lusters may be useful: http://www.glass-on-metal.com/pastart/lusters-mcdaniel.htm
They also list enamel suppliers who may provide information about the process of painting with gold enamel:
There is an "ask the experts" section as well:
The Society of Glass and Ceramic Decorators (SGCD) is another wonderful source of information: http://www.sgcd.org/
To contact them:
Society of Glass and Ceramic Decorators
47 N. Fourth Street / PO Box 2489,
Zanesville, OH 43702
They list the following article: Butterfield, "Characterization Techniques for Liquid Gold Product Development." in their Technotebook publication
E-mail: firstname.lastname@example.org / Contact: Myra Smitley
Another resource is the Society of Gilders:
One of their members may be able to help you. Also, their "links" tab provides addresses for gold products - check the company websites to see if they offer technical information.
Another article by Hunt, looking at the historical origins of gold enamel:
Hunt, L. B. “The True Story of Purple of Cassius: The Birth of Gold-Based Glass and Enamel Colours.” Gold Bulletin, v. 9, no. 4, 1976, pp. 134-139, ill.
