Yes.

99.99% pure anyway.

Here is just one link for the suppliers: http://www.alibaba.com/showroom/Gallium.html

How about handling, since the melting point is almost at room temp....

Would 1 g of gallium metal be enough to demonstrate to a class that its melting point is under body temperature?

I would like to have some cool things to show a class of middle school physical science students (12-13 years old), and a small amount of gallium might be affordable. Unfortunately, at retail, low-volume prices, it will be about $35-40 a gram (instead of the $3 a gram price often quoted), and ~$10 more for shipping, so I would only be able to afford a small amount, if any.

I found wardsci.com and newbielink:http://www.coleparmer.com [nonactive] as U.S. retail suppliers, but I had trouble finding another source for relatively small volumes. Any ideas about where to get some cheaper?

Thanks, Matt

This evening I'll try with 1 g and then I'll tell you.
Bye!

Ok, I have tried with exactly 1g in the form of several pieces (scratched with a knive from the 30 g bulk). I have put them together in the palm of a hand and put the thumb of the other hand on them, sligltly pressing to increase the contact. After about 2 minutes it was melt almost completely.

By the way, gallium stains the hands, so you'll have to wash them after.
