Fluorescein doesn't withstand heat (like any other organic dye)...

Like uranium?

Maybe uranium oxide:


Uranium dioxide or uranium(IV) oxide (UO2), also known as urania or uranous oxide, is an oxide of uranium, and is a black, radioactive, crystalline powder that naturally occurs in the mineral uraninite. It is used in nuclear fuel rods in nuclear reactors. A mixture of uranium and plutonium dioxides is used as MOX fuel. Prior to 1960, it was used as yellow and black color in ceramic glazes and glass.

Somehow I don't see that slipping past the FDA.

Don't tell me my cardboard wings wont make me fly. Go get some duct tape and help me!

Have you ever bought dyed worms for fishing? I'm guessing this is what they use because if you put bits of the bedding into water it glows that weird green color. Thanks User, I wondered what they were using.

It depends who's lobbying for it....

People went bonkers when they thought their restorations from China contained lead, how do you think radioactive uranium oxide would go over?

Ive heard rumblings that zirconia is somewhat radioactive..

You are as well. Everything is in a state of radioactive decay.

Some dental porcelains had salts of uranium in the composition at one time.

Radioactive hugs, anyone ?

Rainbows for you.....

Im not concerned.. but maybe crowns we produce today will be the cancer preventative of tomorrow.

How do dying liquids that 'are not flourescent themselves' , 'add a subtle level of fluorescence'? Sounds like marketing to me.

No "Marketing" intended. 3M makes a line of products called "Lava Plus Zirconia Effect Shades" which is made up of 8 different effect shades in 8ml bottles. One of those bottles is labeled "Fluorescent" and actually does fluoresce. It is NOT a dying liquid, and not intended to be a "Dipping liquid", but rather be painted on. Effect shades are used before sintering and are often used to create characterization on posterior occlusion, etc. The bottle called "Fluorescent" doesn't really have any color, it's neutral but it does fluoresce. Hope that helps?

Id be happy to give it a try and share my opinion...but I don't have any

I use 3M dipping liquids, you can achieve flourecene if you use this option from 3M.

Tayeb, would you mind sharing where you scanned that page from please? If it's a pdf, I'd like to get a copy from you if possible.

You, sir, have lots of opinions.

My apologies.

My apologies.

Keep it. None needed. If my experience is any indicator, sometimes you need a bunch of them all at once.

Just tryin' t' be funny since y' said 'I don't have any'
