Technical Info
sylvus the mad glass scientist

Here is a collection of posts on various experiments and data I've collected about glass. Great science it's not, but sometimes even poor information is better than none.

Depicted above: uroborous sample strand

This post covers what information I've been able to discover about the compatibility between coe 90 (e.g. bullseye) glass and the 7000/8000 series thompson enamels. The upshot is that they're not. 7000/8000 was developed for system 96. Sigh. (Update: I have some new formulations to test from Gathering 2005.)

This post shows the results of experiments trying to determine whether some seed beads are coated (dyed) . The upshot of it is that most of the cool colors seem to be. Sigh. Created 30apr05 30apr2005


Effetre, at the urging of Mike Frantz, has been producing ``hand-pulled'' colors not previously offered in their palette. These colors are characterized by higher cost ($24–36.00/lb. vs. $7-9/lb. for many colors in the standard colorways), less consistant diameter, and, of course, more air bubble...


What I offered to make in exchange was a string of ``Tiffany favrile style glass'' beads using a pixie dust coating. The collector who wanted them seemed very inclined to give me a lot of latitude—plenty of time to make them, and ``no stress'', which I interpreted to mean to follow my artistic i...


This post lists, by metal type, and within metal family, increasing metal content, of some borosilicate colors courtesy of Jesse Kohl of Northstar while we were at Gathering 2005. Someday I'll get around to digging up my 2004 Gathering notes, which include a seminar on this same topic by Henry Grimmett, the head chemist at Glass Alchemy.
