Red face Qlarification for previous post and an apology

Dear Sir,

First and foremost, thank you for your response. Your shared knowledge and time are appreciated.

Second, please accept my apology for being unclear / imprecise in what I was asking for. I am not inquiring about using fuming as a way to make colored glass at torch. Mr. Snodgrass was kind enough to answer my questions and fuming is not what I am asking about. FYI iridizing a glass vessel is classed with fuming for the purpose of my queries. Very different chemical processes and not why I am pestering you and the other people here.

The Rakow library steered my research to Suellen Fuller (Sp?) to demonstrate that making colors via torch work was possible. (She has made a lovely red cited in a CMOG YouTube video.) Her mentor was John Burton. On another YouTube video he uses Colbolt to make a blue he uses in a small drinking vessel.

Concept of the operation for making colors at the torch

With one end puntied up to a tube add the chemicals to the tube. Add a punty to the other end sealing it. Heat to a blob and using both punties mix. Then use as desired.

What reading the wisdom here has taught me is two fold.

First take the chemicals you and the others use and break them down to a percentage by weight. Such a simple concept and I just plain missed it before being permitted to subscribe here.

Second is sadly how much further my research has to go. Borosilicate as a substrate is not 96ish COE soda glass. Hence my question.

I do not mind failing or experiments going sideways. Before I start investing retirement monies, I do want a fair chance of success. Boro is weird, I like it but it is not normal from my research here and other places.

I hope you and others here can either recommend formulas based on boro glass or steer my research for how glass molecules move (word usage?) to be able to make an educated guess on how to tweak chemical components to color glass at torch using boro glass.

Sadly my research efforts have stalled. A big shout out to Schot Glass. They are focused on clarity of their product while I want to add color into it. Exploring what they are doing was insightful but Fe control is not where I want to go.

Conclusion
Once again thank you for your response and please accept my apologies for the poor way I phrased my query. What I am seeking is two fold. First, any insight or concrete ideas for which chemicals produce what colors in boro. Second, the heck with the substrate, what chemicals produce which colors and why. Sneaky third, recommended readings. If you and the members recommend it then I bloody well ought to read it too. Out of print is a tribulation and I am patient when ordering such tomes.

Cheers,

Don
PS: Your time to respond and anybody else's who responds here is highly appreciated. I was sent here by a glass provider when I pestered them, which is a high commendation.
PSS: I humongous TY to CMOG and the Raknow library staff without whose assistance I'd never have discovered glass working beyond YouTube. And, curse you Red Baron for feeding my curiosity. Fair warning Pete and all, you may also get blamed when I pester some one else next. :-)
