Rubino Oro from 2004

[SmithWerx]

Someone has Rubino Oro from 2004 for trade in the garage sale. Can someone please enlighten me as to what's the difference in that Rubino and what's available now?

[RSimmons]

I have four 'shades' of Rubino Oro, aka Gold Ruby. They have the same catalog numbers but look very different. The stuff varies by batch and a few batches have been less than perfect, so knowing the date gives you an idea of how the glass in question might work.

Any input on the quality of the latest stuff? Am thinking about ordering some...

[RSimmons]

The newest version that I have is very transparent and has a slightly more orange-ish cast to it than the some of the older versions. The photo shows 3 versions of the same glass number, the one on the right was purchased about a month or so ago. The others go back several years. I reduced the tips on these rather thoroughly. Be aware that the metal sheen appears to be from lead in the glass.

Rubino will fume to gold due to gold content...(hence, "gold ruby")

and yep, every batch is different...just like with coral!

[RSimmons]

The color appears to be gold, but it isn't elemental gold.

Robert, I too am curious as to what is in the glass all of us are using ,,,,have you found out something about the rubino we should be aware of ? Im always interested in your opinions.

This is something that I've talked about off and on for a long time. When glass is run through a reducing flame and develops a metallic sheen it is due to the concentration of metal on the surface. The metal may be in the form of tiny particles (1/2 micrometer, +/-) and depending on the size, shape and element can impart color as well as the metallic surface. You'll find silver, zinc, manganese and lead, among others, commonly used in glass. High fuel, low oxygen flames (we call reducing flames) can condense the metal on the surface and the color that you see doesn't necessarily correspond to the element that you'd expect. Silver color isn't always elemental silver, gold color isn't always elemental gold metal. The energy dispersive X-ray signal produced by the reduced rubino surface is consistent with that produced by lead. Just remember, many rhinestones, crystals and fine crystal glassware have moderate to high lead content as well.

Thanks for the info Robert.

Thanks, Robert, that was really informative. I had no idea that the "color" represented may not be the actual elements.

[Yvon]

That is good information, Robert. Even understandable in the terms you have written. Thanks.

Thanks everyone. I've had a harddrive failure so I was unable to get back to this to say thanks until now.
