Simple way to differentiate Opaline and clear?

A few weeks ago I cut a bunch of identically-sized strips from BE Opaline and Tekta. At the time, I expected to use them right away, so I didn't mark them. But I ended up moving them aside for another project. Now I've got a bunch of mixed-up strips. Does anyone have an easy way to tell them apart? ...

Re: Drop mold for a spoon rest (open end)

There's a simple solution to that potential problem: Make the mold longer on the open end than the glass you'll be slumping.

Re: Vitrigraph bubbles and craters

The bubbles are in the stringers, so I think you need to lessen the bubbles in that firing. It doesn't look like you have a bubble soak in you vitrigraph firing, and that's very important. I soak for 2 hours at 1225 when I'm pulling cane. I don't make stringers, so I'm not sure if a soak that long i...

I'm guessing, too. You should ask her.

Re: Glass with ceramic inclusion?

Are you sure Christina Bothwell's work has ceramic inclusions? It looks to me like cast glass attached to stone and ceramic, and any inclusions are differently-colored glass.

Re: need info aabout a foto.

Do you belong to the Facebook Fused Glass Fanatics group? Many people posted their pics, process, and (sometimes iffy) schedules there. Go to the group's page, and search for "drip schedule".

Re: fill weight and firing schedule?

Glass weighs 2.5 times as much as water. Weigh the amount of water that fills a heart and multiply by 2.5 for the amount of glass needed.

Re: Microcrystalline Wax

I get mine from Reynolds Advanced Materials - http://www.reynoldsam.com. They have 10 stores; I don't know if one is near you. If not, search for other local sculpture supply stores.

Re: Murrini

The choppers are relatively heavy, but I rest them on the bin I chop into, so I don't get fatigued.

Re: Murrini

I really like M-D Building Products compound nippers: https://www.amazon.com/M-D-Building-Products-49943-Compound/dp/B000FSAUX4 . They require less effort then other nippers. And when I'm doing hundreds of cuts, they're much easier on my wrist. Also, I get more flat cuts by using quick, hard pressur...

Re: OOPS!

When I first read of someone leaving a level in the kiln I thought, "how could they be so negligent?" Fast forward several months... My wife calls up to me from the basement, "Do you have something weird in the kiln. It smells funny down here." I now have a check box in my firing...

Re: Fill in possible gaps?

How about doing a sample firing with pieces matching the areas you're concerned about? Maybe better than finding out the answer with the final piece.

Re: source for float glass

When you buy used float, be sure to bring your polarizing filters. You want to know whether the glass is tempered before you buy it.

Saying a belated hello

Prompted by Marty's "it's too quiet" post over in Spab's Forum, I thought I'd ramble a bit about my relatively new journey in fusing. I've been blowing glass for about 15 years. I started fusing 3 1/2 years ago. I took a course at Corning with Josh Simpson and Gabrielle Küstner (and Gayla ...

Re: Tempered Glass Shards

I fuse/slump tempered shards directly in a mold at 1450. I always get a few needles, and I just knock them off with a file. A small jeweler's file can get in between the shards .
