I really love the DeVardi Indian Marble glasses: Butterscotch and Gray. Very similar in color after working, though. They like to be worked cool, and shaped with tools. Working them hot can even out the color, but shaping the hot glass with a cool tool gives nice variations. I am preparing to buy more of this glass soon.

I bought a lb of the shorts to see if other colors fired me up. Unfortunately they aren't labeled, but one that looks semi-opaque and is about the color of musk melon, handles very nicely. The one that is semi-opaque and gold/yellow bubbles and burns easily.

One note: I pulled some hair think stringers of intense black to see how it handles on the Indian Marbled glass, and oddly, I couldn't get any webbing at all. Mapplied dots or whatever stay very crisp, even on the butterscotch and the gray. Will post pics soon. no compatibility issue so far.

Oh, I'm always looking for intense black that doesn't web. Thanks for the heads up!

That green is gorgeous! I haven't ordered from Devardi (or anyone else) lately, what does the NCN stand for?

Don't know what the NCN stands for.

Has anyone had luck with NCN - Opaque Dark Caramel as a base color for a bead? The rods are very shocky and it boils VERY easily. Every bead I've made with it as base has broken post-annealing. Top colors have been random mixes of Effetre and/or Devardi. Doesn't seem to matter the mix.

As far as I know the intense black from Devardi does not web at all no matter how hot you get it (i tried lol).

I started experimenting a little bit with encasing the opaque white ( I tried encasing the semi opaque but it cracked every single time) since some of the dark transparent are very dark, I wanted to see if I could bring out some of the color by encasing the white. So far, the opaque white seems to be fine with encasing. Here is a set of beads made with a deep blue. I will have to see if I can figure out which blue I used, its either cobalt or ocean blue I believe. And as you can see, it is fine when encased in the clear also.



And this is the jade green with white and mango flowers. The jade green is not a totally solid color, it has a wee bit of streakiness and color difference even in one bead but I really like it.

NCN stands for No Chart Number, meaning it's not a 'standard' color that's been given a #.

I tried the OP Dk. Caramel and got nothing usable out of it. It devits the minute I try reheating it and wouldn't go shiny again no matter what flame I tried. I had one thin band on one spacer bead stay shiny 'caramel' color... the rest, poop. If you want the look of an etched cement-colored bead without actually etching, this is the glass for you. I smeared some SIS on one of them but didn't try any other surface stuff since the Dk. Caramel wasn't playing nicely even by itself.

I made a bead out of a lighter colored glass and the devit made it super cool. I used masked dots of green over it. The green did not devit but the caramel I boiled so hard that it looked like ancient porcelain.

It's great if you can get the look to work for you. I'd love to see a pic of the bead you made.

Gosh, strong pretty colors and neat color contrast too!

Sonja, thank you for the info on the glass and the pics. I have so little time at the torch that I like hearing everyone's trials and successes.

We will all have to post anything we make for gifts for Christmas!

"Ancient porcelain" - I like that! Yes, that is basically where I ended up with the Dk Caramel as a decoration, boiled beyond bubbly to a paler color with a rough surface feel. I think I'm going to put this one on the "unusable" list.

I am, of course, going to have to try out the dark caramel when i get home from work tonight lol. I gave the sop light lime green a go the other day and quite liked it. I will be doing more testing on the encasing as soon as I get chance.

Default Houkje thank you and all who have added to this Great thread.

Houkje,

Thanks for the great pictures and good timing.
I was just finishing up this great thread on Devardi Glass.

Well I have learned a lot about using this glass.

I surely will make an order in the future.
I have a lot of pounds of glass sitting on the shelve to be used at this time.
I also do Lapidary work and have a ton of great cutting rock and slabs.

Like I mentioned to one great vendor in here. I put myself on strike for being a glass addict buying. Lets see how long I can go without a fix of glass LOL. It should be a real hoot its hard to say don't push that button.

I appreciate all the great artist that have added to this thread.

Someday I will add my beads and pendants with Devardi Glass!
Thanks,
Cliff

For those hoping to see some test beads of some of the newest colors (and a couple of oldies too), here are some pics and observations. Most of the test beads are one plain and one with SIS on top. The transparents also have a test bead with CIM Peace as a core.

OP Coffee and Cream - doesn't like reheating - devits/boils


OP Red (47) - lovely red - doesn't go brown like many reds can


OP Dark Purple (136) - lighter than rod after melting. some striations.


OP Dark Caramel - devits/boils galore, especially when reheated.


OP Dark Burgundy - melted nicely but so dark it looks black


SOP Dark Baby Blue (138 ) - LEFT 2 beads - very pretty, opaque, similar to Pajama Blue Vetrofond
SOP Soft Green Blue (139) - RIGHT 2 beads - very pretty - went opaque too - just a smidge softer and greener in color than 138


SOP Light Lime Green - remains translucent if not reheated, went opaque when pressed. Yum!


SOP Misty Golden Gray (161) - RIGHT bead - frit on a stick, semi-translucent white after melting. SIS spreads like crazy. (Bead on the left in this pic is OP Dark Ivory. Devits like other opaque neutrals.)


SOP Violet - LEFT 2 beads - remained translucent when blown into shards, went opaque in spacer beads, more pinkinsh than the OP-136 Dk Purple. Reactive with SIS.
SOP Purple (134) - RIGHT 2 beads - turned a very light lavender, opaque, after melting. quite pretty


SOP Light Misty Green - LEFT 2 beads - pretty soft green. Can go opaque or stay partly translucent. Similar shade as Dirty Martini (CIM), pictured in RIGHT 2 beads, but the Devardi is more minty green.


SOP Fruit Punch - Should have named this one Creamsicle! Nothing like the color of the rod when worked and annealed. (See the unheated rod color to the right in the picture?) Creamy pale orange after working.


TR X-Lt Purple - Quite gray-purple and dark on its own. Pictured over white in middle bead. Full of small bubbles like seeded glass.


TR Beer Bottle Brown (75) - very true to the name! Some small bubbles but not bad. The SIS spreads more on this color.


TR Dark Burnt Orange (17) - very true to rod color. few bubbles


That's all I got! I'd love to see some more results from the newer colors if you have played with them.

OMG LISA !!! Thank you so much for all the hard work on the testing. Reach around and give yourself a big pat on the back from me I'm going to be putting an order in, and after seeing some of your results, I'll add to the list. Thanks also for testing with SIS, as I love the stuff and it's always fun to see how strongly the glass reacts....again, Thank You !!!

Lisa great testing! Thanks for your hard work! I try testing in bits and pieces and always seem to get side tracked. I will be printing your testing out for my notebook.

Well I did some pink lentil tiger beads, I used dark transparent rose over white and black. I am sorry to say all six beads have incompatibility cracks. All Devardi glass, I am so disappointed, I love encasing and the rose is gorgeous over white. I will post pics when I get a chance, I am working extra this week. The dk violet I did over white didn't crack this time, it did the last time I tried it. This is over the opaque white and intense black, not the sop white. I will continue testing the transparents over the white to see what works and what doesn't. But I am really heart broken over the pink, this is the third time I have tried it and every bead has cracked.

Mind you, the dark transparent rose is an awesome color all by itself and etched its totally stunning so I will still be using it I just will have to resign myself to not encasing it.

hmm you know i Just thought of something I might give it one more try. I may do a tiny base bead in the rose, encase that in white then encase in the rose and see if that doesn't equal out the pressure in the bead.

I got the dark rose over white to work when I encased in clear Effetre. I tried Devardi and Vetro to no luck. When I switched I have had no problem. Which is great since I love that rose color!

Bethany do you mean you encased white with dark rose then encased again in Effetre? I am encasing the entire bead in the dk rose. I can encase it twice if I have to if it will work.

I have done both. I love the look of encased beads! But I used the Effetre white and clear with the Devardi rose. I had trouble when I only used it with itself. However-I did not have any trouble when I used some of the first clear I got from them. Just after that first shipment. I also figured out it does need a good heat bath before putting them in the kiln.

hmm I will give that a try also then. I have some time to play today so I will make some more test beads. But I think I will only make one of each and not a whole set this time lol!

I have made that mistake more than once! Looks so good you keep making more and then cry on the kiln when you take them out in the morning! Good luck!

Default WHAT NOT TO DO with a ROD WARMER

Lisa ... Wonderful test beads, thank you...

I have a WHAT NOT TO DO with the ROD WARMER....
I wrap my rod warmer in a fiber blanket to help cool down some of the larger beads a bit slower.. And it works very well (most times).. The other day I did like I always do, make my beads put them in the warmer as I make them.. When I am done for the day, I rewrap the warmer in the blanket and turn off the warmer, works like a charm.. For some reason I didn't unwrap the warmer when I turned it on.. I sat down to make a few beads...As I'm sitting there at the torch I can smell something burning, looked around couldn't see anything so I just thought that a piece of hot glass must have found a dust bunny.. No harm done... I finish making my bead, go to put the bead in the rod warmer and I see the rod warmer is glowing bright orange like a jack o lantern sitting under a pile of snow... (The glow is a great effect, end result not so good..) I unplug the warmer, take the fiber blanket off the warmer, (did you know that if you get a fiber blanket hot enough that it becomes crunchy and will hold the shape of the warmer???) Now if you look at the picture I don't think I need to say more, other than I have a new warmer on order and DO NOT DO THIS...
My DH thought this was very funny and I still do not see any humor in it at all.. In fact I was a bit scared... By the way the silver puddle you see in front of the warmer is (was) an aluminum ridged marver (melting point 933.57 F (660.32 C)), and the small puddle is the case of the warmer...
Just thought I should post this as a safety first, and pay close attention to what you (me) are doing..
