Dear Kavitha Samudrala,
I studied chalcogenide glasses some 10 years ago. I did not know a glass forming region in the Se-Te-Bi system. Can you find it in the literature? If you can not, then you can determine by yourself. I determined the glass forming region in the GeS2-Sb2S3-PbS system, and you can do the same thing. If you would like to see the method, here is my paper link:
https://www.researchgate.net/publication/229905192_Glass_Formation_and_Crystallization_Behavior_of_a_Novel_GeS2Sb2S3PbS_Chalcogenide_Glass_System?ev=prf_pub
However, I know there is a paper showing the phase stability region for the Se-Te-Bi system. You may get something useful from the paper. Check this paper out:
Cook, N.J., Ciobanu, C.L., Wagner, T., Stanley, C.J., 2007. Minerals of the system Bi-Te-Se-S related to the tetradymite archetype: Review of classification and compositional variation. Canadian Mineralogist 45, 665-708.
Hope this helps:)

Dear Kavitha Samudrala,
It should not be difficult to find what the glassy region of this ternary system. You just need some time and some selenium, tellurium and bismuth in order to make all the compositions necessary to determine the glassy region. I don't know this system particularly, but with such a big amount of selenium, the glassy region is not small. Enjoy your glass fabrications!
