First test print with Taulman T-Glase tonight. Extruded really well, adhered well, very nice finish.
The only problem I’ve noticed with my spool of black T-Glase is that I can’t print it at an extrusion width equal to my nozzle diameter. It prints great, but the layers won’t adhere.
Of course, if you’re trying to make a fantastic spring-sculpture, then this is what you use 
@Tom_Sommerville The Black Dye in t-glase will pull the heat out a bit faster of a printed thread. Just keep bumping up temp till you get a reasonable bond for 1:1. Even over temp on t-glase will not harm your nozzle. Too high a temp and t-glase will just create a lot of bubbles.
@Tom_Martz Thanks, I’ll give that a try the next tim I load my T-Glase
