They also don't know how to make the blue glass used for chuches those formulas were lost as well. Copper is the substitute and much cheaper than gold but gold is still used for certain hues as the hues created with copper and gold do not match 100% and also have a different saturation. But in today's cheaper is better world very few people and even less mfg care about such things. :(
Something that might interest you is that Tiffany's favrile glass was patented in 1894 and with some luck the patent explains the process much more precisely. I also found many sources that claim that Tiffany himself invented the process and that it is based on an old roman techniques.
Thank you. Tiffany invented the look in Italy when he saw Schilemann s Pompeii and Herculaneum excavation findings. Every recipe is the Nash product , Americans does everything to honor american Tiffany and to make delete a British Glass Scientist from the history.
Found this interesting to me article it starts with a formula for gold lustre glass
It seems that Arthur's son also had a bit of a problem with Tiffany to say the least.
What I've read so far indicates at least to me that Nash has perfected and modified well known formulas or used more scientific means to get the desired results but is also not the mega genius his son portrayed him to be.
"Tiffany had been experimenting with glass since the early 1870s. Tiffany
and John LaFarge, along with others, attempted to produce glass that came in a
wide range of brilliant colours, and incorporated the leading as a part of the
design. This opalescent glass, which used metal oxides as a colourant, was a
centuries old technique lost to most glass manufacturers who instead used coloured enamels fused in place" from An Investigation Into Louis Comfort Tiffany's and
Tiffany Studios' Architectural Metalwork by Paula Kristina Kulpa
The Americans are not alone in that the brits are just as bad in that regard everything was either invented by a brit or an american. :)
Was Tiffany an chemist or chemical engineer ? If not , no success is possible.
Mustafa was Daguerre a chemist no was Fox Talbot a chemist again no most things in the history of photography were invented by non chemists. This is the case in many fields not only in photography.
Their inventions could be copied worldwide , they are highschool chemistry with todays standards which does not include complex chemicals , color , heat control. Glass have thousands of years of history and Nash made better than all past examples. Photography have 200 years history and your references neither compete with old examples nor used color , melt or heat. If you read your sent link , you find the recipe extremelly complex and non chemist can not accomplished them with balancing all chemcial knowledge between chemicals.
Nash was one of the most successful glass chemist in england and england was the number on on glass research.
Dont underestimate the art and science , Tiffany was a rich man , everyday drinking champagne and spends half of hour in lab per day , at the mornings. You cant underestimate the craftsmen also. Tiffany have only supplied the money like pope in italy to Michelangelo. If pope visited him , he has no role in sculpture making but a moderate keen eye to art like Tiffany.
All the drawings done by women workers at shop and nobody knows their name today , !!!!
As Eastman Kodak has no role in kodachrome.
Don't underestimate the czech czech glass is vastly superior to everything ever made in England. The biggest british achievement in glass was Pilkington and their floatglass other than that their glass was more middle of the run. The truth is that if it was invented or made in the east it's seen as inferior by the west while in reality a lot of products from eastern or in the case of the czech republic center of europe are equal or superior to western products. That includes glass.
I agree with you that Nash was the genius behind Tiffany and before Nash it was John LaFarge. But both is needed the artistic input from Tiffany and the knowledge from Nash/LaFarge without the artistic ideas the latter two wouldn't even have had the idea to create something in the line of favrile glass.
