To find the TC maker type red, I believe the gold based red is what you are going to want.
*How Gold affects glass (Au)* From http://1st-glass.1st-things.com/article ... uring.html
The use of gold can be limited in its use by one factor alone, that of cost for the salts. There is also another point to consider when using gold and that is in controlling the conditions needed to produce the exact desired colour in the finished article. Gold gives glass a rich ruby colour and I am reliably informed by both Sam Thompson (Ex Stevens & Williams) and Stan Eveson (Ex Thomas Webb & Sons) that English glasshouses referred to this as Ruby Gold. Ruby gold is usually produced in a lead glass batch where tin (Sn) is present. A less dark rich ruby gold has become known as 'Cranberry', which has the same basic properties of its rich ruby relative. Many an ex-glassmaker will say it was merely by accident ruby gold was discovered, when a gold sovereign was tossed into the batch/melt by accident. Copper is an alternative to gold to produce ruby glass. The invention of gold ruby glass dates back to 1685 as noted in "De Auro", by Andreas Cassius, in which he describes for the first time the method of producing a red precipitate of stannic acid with gold which later became known as 'Purple of Cassius'. At the time the high price the glass commanded and the efforts need to make it could hardly be justified by its beauty. The principle techniques involved in producing red ruby glass are still based upon Cassius's discovery all those years ago.
Now stained glass would be the quickest way to find that in the quantity you want, but it may not be the fun way. I have seen very few red glass Wine bottles in my last few trips to the liquor store, and never seen clear red at a thrift store. (you can find the not so opaque red in small quantities there if have the patience)
There is that glass shop a block west of the HF, and maybe a dozen others in town, we could try seeing if one has the gear to make glass, and see if we could talk them into giving a demonstration of how colored glass is made, we buy the parts. Just tossing that out there.
