I've seen enough, I decided NOT to buy and try this glass. No matter the lovely colors, I don't want to run the risk of cracked beads or shattering glass when I try to melt it. Just my 2 cents.

well, avoid moretti or vetro odd lots and most handpulled glass completely.

as for cracked beads, that happens with every glass out there...it's not just COE that is a factor, which we all should know by now.

Quite true. I lost a Gaffer bead last week, due to thermal cracking. I spent too much time messing with the surface and not enough insurance heat.

So far, I have had not one bead crack with this glass, unlike others I have tried. I agree that there are all different reasons glass cracks. Look at the silver glasses, there have been posts about issues with them. And the opaline glasses that we now know should not be encased. I think it's just a matter of finding what works well together just like all of the other glasses. I can't tell you how many beads I have lost by using Lausha clear which is "compatible"!

Hi Sweetie. I love the german glasses too! I will have the Reichenbach on my website by Sunday night. I had a sale on something and got buried in orders.

Jim

Are you testing for lead too? The one thing that I know for sure about German Glass is no lead is used in the manufacturing.

Oh C'mon. It's fine to cheer the glass that you like. In this case Devardi. But let's not knock every other hand pulled glass out there. Most Moretti and Vetro Odds do NOT crack. Neither does Most hand pulled glass.

If you lost beads using Lauscha clear it was because you didn't anneal at their suggested annealing temperature or use a conservative program. There are posts all over this forum showing Lauscha clear mixed with all kinds of other 104 glass and when annealed properly it does not crack. The cracking problems seem to be a mostly American thing because of the way we anneal and the fact that most of us don't like to change out program once it's in the annealer. :grin: Me included.
I have even shown photos of Solid Silver Color cored beads encased with Lauscha clear that have survived well over a year.

Cynthia posted this thread so there'd be a place to talk about working with this new glass and our experiences with it so we wouldn't have to wade through a bunch of other posts to see what it's like. It would have been really nice if this thread could have stayed about working with Devardi and the pictures posted by those who have actually used it.

The first Devardi thread is probably more appropriate for the other stuff.

PaulaD 2009-02-27 9:27am

My apologies Bubby. But it came up in this thread. If I posted in the other thread no one would know what I was referring to.
Paula

Bubbyanne 2009-02-27 9:36am

Paula, I'm not singling anyone out in the thread, just more commenting on the way things are shifting in hopes it will not turn into something else. We already have threads here and at TB discussing other parts and feelings about Devardi glass.

I do think your posts about working with Lauscha and asking about testing for lead are good posts and definitely relevant to the thread.
Thank you for that information, good to know. :)

PaulaD 2009-02-27 9:38am

Thanks Bubby!

I think the problem is that many are trying to knock Devardi because of its characteristics and those same characteristics can be found with the common glasses we currently use.

Not to derail the thread but I figured out why a bead crumbled that I mentioned a while back in this thread (I think it was this thread).

It was made from Vetro Bluestone (odd lot at 20.00 a ¼lb) and CIM Hades.
I had even made a small leaf out of those 2 colors and it cracked too...AFTER I found it and the others I had made with that blue glass in the crumbled bead. As soon as I can get to the torch I am going to mix these 2 again and do the freezer test.
I have found a lot of the Vetro odds don't like to be encased and they are prone to shockiness as well.
I'm not even gonna go there about Lauscha clear and cracking...there are a plethora of stories about that fact. Wasn't the reason Lauscha reformulated their clear was to make it compatible with the silver glasses?

I am still being cautious about the Devardi glass AFA compatibility goes (although none of the beads I had made with it have cracked so far) but I know there is a possibility of some of the Dev glass being incompatible but that doesn't make it any different than any of the other accepted glasses. They all have their limits.

None of my beads have cracked yet with Devardi either. Just give it a little more time to warm up, work it a little farther out in the flame, and anneal as soon as your finished (if possible). Beautiful colors and fun to work with! :)

I am very pleased with 2 beads I made using Devardi and Tag turquoise silver. I will post pictures later.

J&M 2009-02-27 11:13am

Here's a few pics...
 
This one is all Devardi

Wonderful glass for bead pens!

Sorry for being a pic hog...
 
This one uses Devardi, Lauscha, & Triton.

Jack, they are spectacular. I love the last one with Lauscha and Triton.

J&M 2009-02-27 11:22am

Thank you. :)

Wow Jack, they are all awesome! My personal fav is the second pic - so colorful! :D

Drafly 2009-02-27 11:34am

Hey Jack, Those are Fantastic! I see you are using silver with Devardi. Have you had any cracking issues "at all" with Devardi?

That statement was referring to the shattering rods, lol, which most handpulled glasses do-especially the odd lots ;)

Cracking happens-due either to user error, just because, or that there's a trick to it (encasing moretti/vetro reds anyone?).

blong2001 2009-02-27 12:16pm

Jack that last one is fantastic!

I have made more than 25 beads and mixed the Devardi with moretti, vetro and tag-no problems yet!

Thank you Beth!
I've been working with it for almost a month now, without any problems. I've used it with my 'Cuda and Cricket and a pair of Invacare concentrators.
Let's see more pics! :)

Yes Olga, your beads are beautiful!!!

Thank you for sharing them with us! :D

Olga, you have made some beautiful beads.

Kym 2009-02-27 3:07pm

WOW! While I was sleeping, you guys are going great guns! Lovely beads, Jack. I have to do quite a few bead pens so that is great that Devardi works nicely for that too. Olga, nice work! Thanks for sharing everyone. I will have to try waking up at 1am in future and check this thread for bead porn.

Cheers
Kym
