Me again........Does any one in Canada still do surcote on glass? Or is there a yellow thru and thru glass progressive?

You might contact the foundry in Dollyville (or Dolly World, or Dolly whatever in Tenn). They actually have a glass casting part and a list published in view of the public that tells one what minerals to add to achieve various glass colors. Also sure that Dow/Corning would be happy to supply such information. Suspect lots of glass/art studios could help or do this for you.

No need for them here is the answer:
Glass Pigments
Compounds Colors iron oxides greens, browns manganese oxides deep amber, amethyst, decolorizer cobalt oxide deep blue gold chloride ruby red selenium compounds reds carbon oxides amber/brown mix of mangnese, cobalt, iron black antimony oxides white uranium oxides yellow green (glows!) sulfur compounds amber/brown copper compounds light blue, red tin compounds white lead with antimony yellow

Almost got it. I keeping getting a shadow of green. Perhaps if you could give me the parts per million of the components.
To infuse glass with color you need the right formula. Its not just lead with antimony, but also the other chemicals that make up the rest of the formula. Then typically you have to heat the lens while in high vacuum. And finally you have to evaporate the chemicals uniformly to allow them to infuse the glass. All while keeping the Rx accurate.
There are a few glass coater's left in N. America in deference to where you are posting from.
I did appreciate Chris's list of chemicals. Great background to have.
Hi Mirror, I wonder if you can give the name of the few glass coaters left in N America....................I seem to having a disagreement with my wife, she doesn't like me taking up the living room constructing the vacuum bell and my dog keeps eating the chemicals.
I will be surprised if you can supply those lab names.
PM sent.
