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.)

More kiln fired seed bead (&c) color permanence tests...

 

Sample strand of some of the Limited Edition BE colors from 2007 (more or less)---the so-called 1001 series. Originally posted 8jan08.

 

The very first beads I made with the Color is Messy pallette. Made in October, originally posted 16nov07.

 

sample strand for the current creation is messy color is messy (104coe) palette. Originally posted 27oct07

 

Comparisons of 4 blacks---Effetre 064, 066, hades0820 and vetrofond 064 on vetrofond 204, Effetre 208, and Thompson enamel white (9010?). Originally posted 21oct07.

 

More Gathering goodies, v. 2007, including some just-a-demo-ugly tests. Originally posted 16aug07

Simple hollow beads are remarkably durable when dropped onto concrete floors, but double hollows illustrate one of the vulnerabilities of hollow forms. Originally posted 28jan07

At this point, pages of dichro color strips used to make dichro solids.

to your left, the orange bead that didn't make it into the 96 coe pi glass sample strand; see also the post 96 coe uroborus sample strand. Posted 04 and 05 may, respectively.

 

This post is mostly self-indulgent, but does include one tip for marking rods. file created 08 aug05, posted 13aug05

 

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

 

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.
