Hate Rubino HATE HATE HATE it today

[InsanityBeader]

Ok, Im getting so frustrated. Lately I can't seem to use rubino without it getting burnt spots in it. What am I doing wrong? I was so careful today... heated up my rubino rod more toward the end of the flame, cleaned off the end... made sure I didn't pull the bead in too far, melted in the rubino and just as I was finishing up a bead I spend 45min on... the darn petals formed these black burn-like marks. GAAAAAAAAAAAH! Im so mad!

help :(

Try making your flame just a little oxidizing. I get the grey spots when my flame is reducing.

Ellen is right. Turn your propane down. If you're on an HH, well, good luck, I never had luck with rubino on a HH. BTW, rubino does not like being worked for a long time.

Have you tried a Czech glass color called Tourmaline Pink? It's half the price of rubino, strikes easily, looks identical and is not fussy like rubino. The only probem is that it need to be heated hot to strike, so it's not useful for designs with raised stringer, however, it works fine for flat petals.

It's available at www.checkglass.com

Oh and don't put it directly onto ivory. Blech!

[InsanityBeader]

I had heard not to put it on ivory. That pink sounds interesting.... What brand of glass is it?

Im not on a HH but minor bench and oxy con. I'll keep these tips in mind but I am not touching the stuff any more today. Just too frustrated!!

Thanks!!

The tourmaline pink is Czech glass. I don't think it has a brand associated with it, it's just from the Czech Republic. It's compatible with Effetre/Vetrofond. If you look the website, you will see several different types of glass there, but you want to look in the soda lime glass section. Even so, not all the colors are compatible with Moretti/Vetrofond, so be sure you pay attention to the COEs of the different colors. I just love some of their colors, especially the transparent glass, they're gorgeous and the tourmaline pink is one of my favorites.

Is your propane low? I have had this problem when my propane tank was nearing empty. Refilling the tank helped a lot.

I am so sympathetic about this!!!
I also have the same problems with some of Vals frits.
I thought getting a second concentrator would help. But even with 2 I still have this problem. I think I have momentary brain farts that allow my bead to slip to close to the torch head. For an imperceivable microsecond, which apparetly is all it takes to generate onef those gray/black irreversible reduction spots!

I also have problems using it on flower petals... I make white petals, then add rubino toward the inside of the petal to make a two tone look. I often get this separation between the pink and white. So my petals are pink in the middle, then a stripe of nothing, just clear, then white petal again. Someone please tell me what this is about? I'm baffled and frustrated!

Vetrofond makes a tasty rubino oro (791456) and available at Frantz Art Glass, with a 1/2 pound limit for the time being. It is already struck and sweet between the teeth.

I'm such a dork :roll: !

Ummm......excuse my ignorance, but what does "sweet between the teeth" mean?

[InsanityBeader]

Hey Mike, do you think that vetro would be nicer to me??

Btw.. I think my tank might be low... noticing that the pressure seems to be low . I'll refill before I try again!! Thanks all

Im guessing it's sweet like a jolly rancher you decided to chew up. ... ok, I don't have a clue, lol... but I figured it was a positive comment.

This is one of the reasons I love Bullseye; their pinks don't do that, plus they have a variety, light pink, salmon pink, cranberry pink, cranberry sapphirine pink, streaky pink, etc. And these are all transparents. They have a lot of opaque pinks too.

[InsanityBeader]

I only have one oxy con so I was under the impression I really can't burn hot enough for boro yet :(

[Bubbyanne]

Are you using the unstruck rubino?
I am on a HH with bulk propane and had a batch of the old pre struck effetre rubino, never had a problem. Got the new kiln strike stuff and am getting spots of grey gunk pretty frequently. Frustrating to say the least!

I use rubino for my roses and theres nothing like spending an hour and a half to have a bead ruined by a bit of shmutz in the center of your flower. I had to switch to pulling frit stringers to make the roses. Which was a blessing in disguise, they look much better that way. LOL!

I just ordered the vetro rubino Mike was talking about. It should be here in a few days and I can't wait to try it! :D

I'm on a HH too and get super hot pink out of struck and unstruck Rubino rods. I guess I was given the gift of Rubino-ability! The only trick I have is I set the rod on my graphite marver before I put it in the flame...then I flash the crapola out of it for longer than you'd think was necessary...but when it heats nice and slow like that...I can literally watch it bloom pink. I also start out in the tip of the flame...but I'm able to get fairly close in without it mucking up on me...just have to know where that invisible muck line is. Goooooood luck. :)
