I am at that age Robin....serial killer glasses and somewhat of a hermit. It was a shame I could not figure out the annealing schedule for these morsels. Only about half of them were stable after fusion. The white glass was not amiable to melting as is often the case. They 'eye' was done by grinding a flat base on each milifiori bead and setting it on end for a collapse. Some of the milifiori was 2.5 inches in diameter go figure. Perhaps the prelude to being stretched to bead diameter. No telling what those oversea dudes were up to. Judging from the colors they melted some obnoxious metals to derive at colors. They are perfectly safe now that they are in glass form. jamesp what temperature were you holding them at to anneal them? Probably 800F. The other problem is that the white glass wants to bubble causing weak areas. It is (temperature) soft glass and needs a cooler heat schedule too. I just never tried many test schedules due to complexity. And I think they mixed COE's too. No where as friendly and fuse compatible as the big load of art glass. I settled on about 60% success using regular heat schedule.

Before tumbling. They appear to be partially tumbled upon receipt. Sized perfect for tumbling except some big pieces. There is a mix. Some very strange glass in these batches. It takes a fine polish if you can master the glass polish challenge. Those are some mighty fine eye candy, James. So, apparently, they like to live in bowls just like polished rocks? I've got a few shiny rock lairs around my house. What I'd love to know is how to keep the dust off of them. Magic spells? Find a dishwasher friendly basket and chunk em in the dishwasher Jean. Don't tell the lady of the house he he.

Now, that's an idea, James. Unfortunately, the only dishwasher I have are the two appendages at the ends of my arms, lol. Nothing to tell "the lady of the house." However, I would definitely wring somebody's neck if they used my good skillet to fuse weld plastic. Some things are sacred...

Unfortunately the kitchen is loaded with desirable implements for experiments and process operations. Wife married the wrong man !

Just got my order of this glass in the mail. Looks great, can't wait to see how it turns out.

I ordered 3 lbs, quite a bit of it is very small. Could I use it in place of ceramic media?

You may want to add the softer glass later in step 1 so that it does not grind to nothing though. Glass will wear to nothing when shaping agate and other hard rocks for weeks. Those should be shaped in 10 to 14 days in a small tumbler. Or you can run just a few samples in a rock run just to see how fast they wear. I like to do step 1 with 100% glass so they all shape at the same rate.

For a while, I was using glass Marbles as smalls in stage 1 tumbles. I think it was working but as Jamesp says, they do wear out in about a month.

I have been using the small bead glass for filler and smalls(basically the same as using ceramic media in a rotary). It has been used as filler a couple of times and is almost rounded enough to be finished/polished in the vibe(or rotary if I knew how to polish glass in a rotary). Tis some whacky glass.
