Old glass question

[praxidis]

After a nearly 10 year absence, I'm getting back into making beads. I was digging out my stored stash of glass and picking out some odd colors to use as practice rods...I was just messing around with my HH and found one rod of green glass (kind of an opaque almost jade green color) that developed a reddish-orangey kind of streaking/webbing on it when it cooled.
As far as I can remember, I purchased most of my glass back then from Arrow Springs, but I did buy a few rods from the stained glass shop (long closed now and I'm across the country) where I used to live. I'm pretty sure it was all Effetre, but I don't remember working with this color before.
Can anyone tell me what this might be? I only have this one long rod of it, so if its something cool, I don't want to waste it on practice beads.
thanks!

Turquoise glass is made with copper which sometimes surfaces in a reducing flame which is what you have working on a hothead. It can be a cool effect.

Depending on what you mean by opaque almost jade green, it could be Petroleum Green, although what I would call jade green is Nile Opalino and that is unlikely to web with copper.

A picture of the rod and the bead would be really helpful.

[praxidis]

Its a tough green to describe, its darker than celedon, but not as dark as the petroleum green...
I know these are bad pics but I hope they are enough to give you an idea.
The bead is still on the mandrel, and it isn't a good one at all. When I saw the webbing forming, I thought it was getting scummy so I pulled it out and just stuck it in the vermiculite. Wasn't until much later when I was just going to throw it in the water bucket that I pulled it out and saw the coloration

red copper green maybe?

[Three Muses Glass]

Mosaic green maybe?

[praxidis]

I would love for it to be red copper green, I just ordered some of that! lol
Stands to reason I probably have the same tastes in colors as I did back then so maybe...:grin:
it *kinda* looks closest to that color from what I can tell (like on the Frantz website) but it is hard to see.
If it helps at all, as I was making another bead with this rod, I could see a silver like shimmer flash across the surface as it eas being heated.
Doesn't red copper green have a reaction with ivory or dark ivory? I'm going to go back out and see what happens.
Thanks for all your input!

best guess....red copper green

[SadiesJewels]

Looks like Mosaic green to me in the picture ... also gets a red in reduction flames.

[Flonche]

Your description also makes me think of Red Copper green OLD version. The new one is completely different, the rods are red with a green core and the finished bead is much redder than the soft pink and turquoise tones of the old one.

[GlassMigrations]

Tribal Turquoise(ASK), no longer in production, has the red tones in it after being introduced in the flame.

Ooops, after reading your post again about it being 10 years ago, it wouldn't be the Tribal Turquoise. Oh well, I tried.

[praxidis]

Thanks everyone for looking and giving an opinion. Sad to say, there is pretty much no way of knowing for sure I guess. Of course, after moving so much, I can't find any of my old glass notes they probably would have helped some. I made a few more small beads with the green, but have saved a little more than half of the rod for a special future use...I'll see how it compares to the red copper green shipment I expect in a day or two.
Thanks again for all your help-

[Shrimp]

I'm looking foreward to your comparison photos Prax!

[Elizabeth Beads]

The rod looks like it could be regular Copper Green, which does get that silver shimmer.

mosaic green or what now is grasshopper green,.. dont know what it used to be... goes red/orange on me almost every time I over cook it, which is not hard to do at all!!!

[praxidis]

Next time I order some glass, I'll pick up some of the other greens to compare.
I really like the effect that the first bead had, the webbing shades to reddish/orange/yellow/ochre in places. I made 2 other beads with it after I noticed what it did and they did not look as nice. Better shape but had streaking rather than the more attractive weblike color change the first one had.
It would be very cool if I could reproduce it. When I made the bead, it was the first one of the day, with a fresh tank and I just grabbed what I thought was a boring color to practice with. I just let the glass melt and I wasn't really worrying too much about the condition of it, I was concentrating on relaxing, getting the kinks out (its been a loooong time since I've done this) and mostly just the shape.
Then I saw the silver flashing a little, then the black streaking appeared. I got a little apprehensive and I thought at one point my gas or the HH was dirty or I was "burning" the glass. Thats when I just thought I'd start over and stuck it in the crockpot-didn't even look at it. It wasn't until later that day I saw the color that happened. Its funny, I don't have many rods of opaque in my stash, and I specifically don't remember having any colors that were known to do anything like this....:-k

[chrissij]

and here I am thinking it's Petroleum Green. I can send you a rod for comparison.

[Rareripes]

Chrissi...I'm looking at my Mosaic and Petroleum Greens.I tend to agree with you..looks like petroleum to me as I press my glasses up to the screen pic ;)

[praxidis]

and here I am thinking it's Petroleum Green. I can send you a rod for comparison.

Thank you! Thats very generous of you to offer! That way, between that, the mystery rod, and what shows up in my order I might get a better idea of what it is.

[chrissij]

PM me your address.

[praxidis]

Here is a picture of the bead I was talking about at the beginning of the thread.
I know, the shape sucks, lol, just look at the color and see if it looks familiar.
I'm kicking myself already for not paying more attention and making a better bead! lol

[praxidis]

These were made using a stringer from the mystery green rod and ivory/old ivory as a base. The green went crazy!
While not perfect, these beads are better shaped than the other one...lol.
Hope these pics help!
Thanks-
Prax

[Elizabeth Beads]

I'm changing my guess from Petroleum to good old Grass Green.

[praxidis]

Whew...thanks for clearing that up!
I:happy:
Now my next question is....does the grass green available now still do this?
Thanks-
Prax

[Elizabeth Beads]

Changing my guess yet again - different monitor, different color. Mosaic Green. That's my final answer.

I'm pretty sure that if you cook it just right, the new stuff will web copper too.

[jaci]

grass green I think.. I now see it seems to be a brighter slightly lighter green compared to petroleum (usually goes silver-y on me) or mosaic(almost has blue-ish streaks in it). AND it does exactly what my grass green (grasshopper green) does every time :)

This is my grass green. I had a great idea.. Then the green went orange/red... When I played with it to more in a few small beads, same thing. Red orange-ish. I was actually disappointed, I wanted the green to stay green!!! oh well

[chrissij]

It does look more green/green now. I'll see if I can dredge up a few not so short shorts of each color.

On a side note, I seem to recall mosaic green being changed somehow, and was advised to hoard my old mosaic green. Is that true?

[Flonche]

Definitely not Red copper green

[jaci]

oh yes it changed about 5 years ago... I think its not so much changed, but more like the "coral's: type of thing! :lol:

Thinking of that fact, the earlier Mosaic green DID web more than the Grass green, and was about that color. The Grass seems to just blur more than web, but I remember the WEBBING specifically on a mosiac green a long time ago. Im gonna bet it is mosaic green. I had a bead that had very similar webbing to the 1st in the latest pic's. I had added some color i think, but yes the webbing was very much the same. Like cosmic gaps.... or baking soda beads, or something. Not like a spray can blur.... The Grass gets the blur... yes MOSAIC GREEN....the early years.

[kbinkster]

Mosaic Green is a little bit translucent - just a little, not completely opaque-looking like Grass Green.

[praxidis]

I'm going to order up some glass today, and pick up a small amount of each of the greens in question. I have to work in the real world for the next few days so I won't be able to get to any bead making until Tuesday. My schedule is pretty light next week though, so I hope to get a lot of time in after then.
I'll post updates with pics.
Thank you all for your input...I'm trying to be optimistic about finding the right color glass but I also know that formulas change and 10 years is a long time.
I'm keeping my fingers crossed but we'll just have to see.
It would be great to find that its still out there because those colors are among my favorites and I can find a great deal of use for it.
Who doesn't love a mystery, right?
Thanks again everyone!
Prax
ps: here is the pair of smaller beads from a different side/angle:

[praxidis]

Here is one more pic of a bead made with that color. It seems brighter than the others, maybe because there is no ivory in this one. Once again, please excuse the shape...I think I had too much coffee the other day and was rushing-lol.
I also need practice taking bead shots too!
Thanks-
Prax

[jaci]

it is either petroleum or mosaic.. oddly enough, I was playing with both when I was playing with BOTH at the same time, and can not remember which is which right now. humm... off to the color chart!!! BRB.....

[kbinkster]

Petroleum reduces red for sure!

[praxidis]

I just finished up ordering a handful of the each of the greens mentioned to give them test drives.
Green is one of my favorite colors anyway, so no matter what happens I'm still good-I'll use them one way or another.
Thanks!
Prax

oh I forgot all about NILE GREEN! It looks really close, and has the same characteristics of the webbing and such :O

LOL-I looked at the Nile green when I was ordering and it just didn't feel right...I think its a touch too blue, but it does show some of the veining though.
Nile green was the one green I *didn't* get this time around-oh well-I'll just have to wait and see!
Thanks!

[praxidis]

I hope this mystery will get solved tomorrow...thats when the UPS tracking site says the shipment of glass will be here-I'm excited!
Prax

[jaci]

woohoo! lol

[chrissij]

So, I don't need to send glass? I haven't printed the label yet because the stupid USPS online site requires "Priority" packaging, so I had to order that... :roll:

[Listenup]

Sorry I didn't see this before. Check my online charts where I tested almost the entire Effetre line as frit for reactions or such. May help answer your questions. Most of the greens were made with broken rods purchased pretty close to 10 years ago.
http://www.listen-up.org/kitty/beads/frit.htm

My vote would be that it's grass green.

chrissij-
It was very generous of you but, I'm thinking thats not neccessary now.But if you have incurred some cost for postage I can reinburse you for that.
:grin:

Wow,Kay..thats a wonderful reference chart!!! Thank you for posting it..its bookmarked now :)

[praxidis]

Wow!
Listenup-that is a fantastic reference chart!
And now the answer....
All of you who said "grass green", welll....I'm betting you're right. Side by side, the rods were the same color and degree of opaqueness. Its not done cooling down yet but, it sure acted similar to the old stuff in the flame...it flashed silver a lot, and there was some webbing visible. Not sure what color its going to end up as yet.
I'll take pics and post them in the morning.
Thanks everyone for contributing to the thread and helping solve my glass mystery!

Now, I have this yellow....:-k

Nah! Just kiddin'.
Prax

[jaci]

I am glad that you have found an answer for now :) happy torching.. ill be waiting for the next mystery!! I have way to much fun with these things! LOL

[praxidis]

Here's the big reveal...
(left to right)
1) Petroleum green
2) Mosaic green
3) Grass green

While all of them had striations and webbing to some degree, the Grass green was the only one that had red come out on the surface-not as much as the old rod I had but it is still present. I tried to work all three for the same amount of time to try and be as accurate as possible.
As an aside...I love the Pet Green!!
Thanks again everyone-
Prax

[Listenup]

Pet Green is easy & fun to mix - I think I can do it in my sleep now I've mixed it so much. I could tell instantly that the color in question was NOT Petroleum Green - not enough of a blue tint.
