Moretti Glass Beads - I by froggynaan Moretti Glass Beads - I by froggynaan
Here are 25 beads that I made recently. I have nothing to do for a while until I move into my apartment. For the time being, i'm perfecting my swirl.

-----------------

Information about these glass beads:

They are made of Moretti glass. It's a soft glass that melts at a relatively low temperature (working temp around 1400 F). I use a cheap (low-cost) torch which screws directly onto a standard propane cylinder. It has air inlets to mix the gas with atmospheric air, not pure oxygen. The flame is not very hot (compared to oxy-propane torches) and it's also somewhat sooty.

-----------------

If you want to comment on a particular bead, Please refer to the beads by their matrix coordinate as in this convention:

[[11,12,13,14,15],
[21,22,23,24,25],
[31,32,33,34,35],
[41,42,43,44,45],
[51,52,53,54,55]]

The middle bead would then be called "bead three-three"

I use Moretti/Effetre. It's a soft glass often used for beads but less often used for sculpture. I think the COE is 104E-5 in/in*F. I sometimes use Mapp gas, but when i was in highschool and i didn't have much money i use propane with a hot head torch. It was tricky.

I use moretti (104 i believe). The units of that are micro-inch/inch*degree celsius, or micro-strain/degree celsius.

Muddy color can be from a sooty flame or from too hot of a flame burning out your colors. If you're using an oxy-propane torch, that latter is more likely. Just try to keep sensitive colors (opaque green i think is sensitive sometimes) to a moderate temperature.

If you're using a hot head, the muddy color is from a sooty flame. If you turn the gas up too much that will happen.

I use gray bead release. It works well. The only time it doesn't work well is with new mandrells that have petroleum on them. That makes them sticky. They're packed with petroleum so they don't rust, but it comes off after a while of using them.
