I've made several bead sets using rubino oro, I don't have any problems when 'annealing as I go' but when I batch anneal this happens:

And after

You can see the problem, I end up with a murky purpley/pink, I used the following programme
PRO1
Ramp1 149C
Temp1 520C
Hold1 60mins
Ramp2 78C
Temp2 371
CHold2 0000mins
Ramp3 0000
My kiln is a Paragon SC2.
Any Ideas?????
Very bizzare - I have an SC2 and use pretty much the same schedule - so I can't help you.
But it has been said before that kilns are like cars - may look the same, but they handle a little differently!
Sorry - that doesn't help!
they might not be what you wanted, but they are still pretty :) they might have struck in the kiln??
I've had the same happen to me ....
Before...

Different bead, but the same has happened to all of them :-\
Had me going there Les - thought the kiln fairies had reshaped the bead ::)
;D

My beautiful cat also cracked in the kiln, so I'd say it was a pretty bad kiln day today :'( ..... I mustn't have cooled it gently enough, so it went in the bin in disgust :'( :'(
I hate having to batch anneal :(
Well, if I was a kiln fairy, I'd have snaffled that cat!
I too use almost exactly that schedule with no problems as yet.
Do you think it has anything to do with something in the base glass?
...was typing this cross-posting though - have just seen cat cracked...that's such a pity, he was gorgeous...
Hmm.... don't know about schedules... I've got an old fashioned ceramic kiln with very basic controlls, but this has never happened to me before.... broken beads cos I batch anneal is just a hazzard of the job :(
I'd give my right arm for a proper glass kiln... I'd love the luxury of being able to make more complex beads, annealing as I go :(
xx
They're still pretty though.....
Sounds to me like there's a lot of problems with rubino right now - either you're all bought Sarah's book and are using a heck of a lot of rubino OR there's a problem with a particular batch. I thought I saw something else about rubino going milky/changing colour etc? I've never come across this before so it might be worth you all conferring over where and when you bought your rubino. I'm betting it has all come from the same supplier and has a problem.
Hmm.... dodgy batches ... probably is, knowing my luck :-\
For the first time ever I have bought a whole bundle of it... I normally only buy it in single rods as my results have always been pale and burnt out, but I was determined to finally get to grips with rubino properly...
Never mind... I do still like the effect though... it has gone a beautiful deep lilaccy pink :) Wonder what it'll look like etched....
*off to dig out the etch all*
:)
Thanks, everyone. I wonder if it is a batch problem, I've got some more purchased at a different time so will try that.
I'm even more upset to hear about the Cat :(
Aww... I'll live :-\
I can't have a go to see if it's a dodgy batch as I'd got no rubino in at all before I bought this lot... could you let me know how you get on ??
Les xx
Will do when I got some torch time.......4 kids trashing the joint at the moment...roll on 3rd September.
Ha ha ha ... I soooooooooooo know where you are coming from... ;D

Perhaps while you're at Stourbridge you could buy another rod - and give it a go???
Only other thing is to note down what glass you used it on top of - and perhaps the others who have reported the same thing today can do the same and you can compare notes!
With the ones I put at the beginning of this threat it was just over white.
I've used it over EDP and various transparents but annealing as I go with no probs.
Maybe it's the white ???
I've used it over Effetre pale pink and a couple of other Effetre colours that I can't remember exactly... not white I don't think though - and Gelly's Sty. All batch annealled. I have some rubino from a different purchase so will have a go with that over the weekend & see if it makes any difference... I wondered if it was the batch annealling causing the problem?
I don't know.... I don't use rubino often enough to comment... but I do know that on the odd occasion I have used it in the past, I've not had this problem..
I'm stumped ???
That cloudy pink is lovely though - never seen it with rubino, looks like a Bullseye pink. If it turns out that the batch is a rum 'un I'll happily swap stuff for some of it!
he he ... I've got plenty :D
xx
I have some rubino I bought a while back, I've not had this problem, but then I don't batch anneal.. if you suspect that's the prob, I suppose you need to try a session annealing as you go..
I had this problem batch annealing rubino in my SC2. The effect is quite nice in a way, but disappointing when it's not what you want. It's actually putting me off annealing my rubino.
Btw it happens whatever I do with it - just on it's own, layered over other colours and encased...all purple. :(
All the rubino I've used recently has come out of the kiln as it went in. Plain rubino came out a great raspberry colour. That was batch annealing in an SC2. It is glass that I bought over a year ago, though, so not a recent batch.
Well I etched one and I like it ;D

Oh yes that looks much better, I'm going to try that with mine. Ta. Kate x

Oh that is a real shame that cat is beautiful, :-\
I'll have tp make another one then, won't I !

Hey - sounds like everyone could be kept happy here!!
BTW - I batch anneal in an SC2 and have not problems! (in fact since I boght Think Pink I've had better results!)
I bought some new rubino off Martin yesterday as it looked interesting. It's more "raspberry" than "cranberry" in colour and looked slightly cloudy.
I've done a test bead with this new stuff and a test bead with my existing rubino stash and let them cool in vermiculite. They both look like rubino should do.
I've just put them in my kiln as I've got to batch anneal some beads for an ex-student so we'll see what comes out tomorrow.
I must say that I've never found rubino to be consistent over the years. I tend to buy a bunch of it every 18 months or so (as I don't use it in huge quantities) but on each occasion I have bought it, it has been very different to the last one. The first lot I had was claret-like in colour and the colour strength was brilliantly intense. The next lot was actually clear and had to be struck in the kiln. Even then the colour was wishy washy. I've had rubino that had a gold/brown haze around it when encased. My last lot is okay but not as intense as I would like. The stuff I bought yesterday just looks plain "wrong". It shouldn't be cloudy? Oh well - guess we'll see what the kiln fairy brings.........
That's interesting because my original batch was slightly cloudy looking (the one I've had the problems with, and a subsequent batch is exactly the same, not knowing any different I assumed that's just how it is. But yesterday I noticed that a single rod that Kaz bought over (part of a little glassy gift, so lovely of her) is completely different, much clearer with a raspberry appearance.
I'll have a go with it when I get time and see if the results are any different. Kate x
Yeh, it does possibly sound like a batch problem. I only ever batch anneal, and have never had this effect from Rubino. But like Sal I don't buy loads of the stuff and have noticed differences when I have bought new rubino rods. The batch I'm using now I bought probably over a year ago, and is quite a deep cranberry colour on the rod and works the same.
Such a shame about the cat Les - he's so cute you should definitely make another one! ;D And I quite like the etched bead - it's a lovely soft colour. But I can see why you're miffed Kate, I would be if my beads had changed that much, they are still really pretty though. They look almost like they are made from EDP, that pinky mauve colour, I wonder whether the 2 colours (EDP and rubino) share similar ingredients? ???
Sorry I can't be more help - let us know how you get on with Kaz's rod - fingers crossed.

I'm reading this with interest, I find all the differences in glass fascinating.
Helen, Ingridh on LE says in her "Sweet Dreamy Purple" tut that she thinks EDP is an attempt at opaque rubino, by mixing it with opaque. The way EDP seems to separate out, you can seem to bring out the glossy rubino colour.
'Morning campers! :D
Thought you might like to see what I got from my batch anneal:
(http://homepage.ntlworld.com/adam.carver1/Rubino.jpg)
Definitely a batch problem then. The one on the left is an old stash of rubino I have (can you see the goldy/brown haze? - kinda ugly). The one in the middle is an ugly bead - apologies for the lack of dimple - the phone went and I just dumped it in the vermic! The one on the right is the new stash I bought on Saturday.
So, is everyone saying that you don't get this purplish effect with hot annealing? Strange...... ???
My advice would be to hoard your stashes of this new rubino. I LOVE the EDP colour but always struggle with the devitrification. It may not be rubino as we know it Jim, but it sure is purty......... ;D
I ordered some from Martin when he was at Newmarket, and when I got it home (it was pre-wrapped) I was convinced he's given me the wrong glass (thought perhaps he'd given me CIM?)
(http://i39.photobucket.com/albums/e160/shine-on2/June08040.jpg)
The top 2 were the normal cololur I'd expected - and I got the bottom one - completely different. But when I looked sideways on I could see the "Rings". So I emailed him, and he assured me it was Rubino Effetre. But I have to say when I've used it, it's been fine. I felt better when I read Think Pink and Sarah mentions the difference in colour!
That said - if it is going cloudy - and there are a few of you with the same problem, it could be a bad batch!
Yes, when I saw it on Martin's shelf at Stourbridge I thought it was CIM too!
Mmm that makes sense Mary, I'm guessing there are only a limited number of chemical constituents that go into the glass colour palette and will withstand such intense heat. So different bases with similar pigments are used.
I rather like the EDP effect Sal, I love the colours you can get from EDP, but always get devit whenever I faff around too long. Might have to get some of the new rubino and have a play.

Sal, the one on the right looks familiar...here are some of mine, before and after annealing;
(http://i171.photobucket.com/albums/u286/Spookyjewel/005.jpg)
I got mine from Martin about a year ago and the rods are actually a very pale pink - almost clear, although they do go dark when heated.
Yep mine too, I had a mix of very pale and a couple of pinker ones, but they are definately not purple..

The differences in colour is down to the thickness of rubino over white, the one on the right being the thickest..
That bead on the right is beautiful Sal ;D
If only I'd known I would have bought some :'(
I might be on the 'phone to Martin in the morning

Oh yay, now I'm excited!
I bought some on Saturday too, I thought it looked so gorge that I'd try to get it like the colour of the rod when made into a bead.
Interestingly though, I got this lovely purple translucent colour when my kiln went wrong last year and overheated on my annealing cycle. All my beads ended up flat on one side and my rubino went this purple like you're getting.
I wonder if it's possible to get the normal rubino colour by reducing the annealing temperature to it's lowest, after all it is an annealing range.
I use lots of rubino, and love how it's different! I can't wait to try this new one, and like Sal, if you don't want yours, I'd be interested ;D
Ive never had rubino before and I bought some from martin at stourbridge. its definitely this milky cloudy stuff that youre all on about...
I usually anneal as I go and have not got any of it to be transparenty like in sarah hornik type beads
I have to say I quite like this milky raspberry thing its doing, thought it was just me though and that I was doing it wrong, nice to know I'm not!
and it most definitly has to share some ingredients with edp, on the rods I have used there is a slightly pinky purple pale opaque ring around the end I have heated exactly like edp looks
if anyone wants to swap a rod of their transparenty cranberry looking one for one of these to give it a go(if they like the look that is!) I'd be glad to, I'd like to know what its meant to do! contact me on website, I check it more often www.madelinebunyan.com or come find me on LE
