Here's an overgeneralization (so no, it's not completely right) that's good enough to go on: for lampworking purposes, if it's not boro (COE 33), it's soda-lime a/k/a soft glass. All those other COES -- 120, 104, 96-ish, 90 -- are soda lime.
Here are some of the reasons that's not completely right. Satake (Japanese manufacturer of soft glass) also makes some leaded glass, which actually includes some of its prettiest colors. So, not exactly soda-lime glass. I think there's also some Czech leaded glass.
There's also quartz, which is the other extreme -- hard beyond hard. The only way you'd run across it is as a punty for something. I saw a reference to it here today as a punty for holding silver or gold for fuming glass -- great if you want to make sure you won't melt your punty, but not really necessary unless you're using a Big Serious Torch and are having trouble with boro punties melting.
