A BRIEF DESCRIPTION OF THE GLASSMAKING PROCESS
NOTE: This information has been found in a file of old Club Newsletter – this one from the Northern California Club, dated 1989.
The chart was compiled by one Art Edwards of Fenton Art Glass Co. …..It is certainly worthy of reprint here. Enjoy!

Boyd Glass in Cambridge Ohio
My name is Bob Applegate and I worked at Boyd Glass in Cambridge Ohio for about the first 8 or 9 years they were open. Anyway, I just wanted to let you know that I found your website and thought the information on it was very useful. I think it is great that someone cares enough to compile the information and then share it with others. With the Boyd’s ceasing glass production this year, I am afraid that glassmaking by hand is becoming a dying art in the USA. And with younger generations being collectors of electronics in place of glass, I am really afraid that trend will continue. I hope not. I hope this is just a downward trend comparable to the Depression, WWII, and other times, but I am afraid that may be an unrealistic hope.
That being said, the information on the chemicals needed to produce glass as compiled by Mr. Fenton is a very good article. However, I am sure that you are aware that the most common way for glassmakers in the 60’s, 70’s, and beyond to make red glass, whether it is a ruby color or an amberina style red, is to use a mixture of Selenium, Orange Cadmium and a few other rare earths. Sometimes the pieces will need to be “warmed in”, or reheated after being removed from the mould to bring out the rich red color but not always.
As I said, I am sure that you already knew that but thought I would share the information anyway. We made quite a few red colors of glass at Boyd’s and although saying the use of gold to make the red color seems romantic, expensive, and historic, it is not always the case for all red colors. Some reds require gold yes, but very few.
Again I want to thank you for taking the time and trouble to compile all of the information on your website, and for sharing the knowledge you have gained over the years of collecting glass. It is very, very generous of you.
