Cobalt, the Mineral...from Wikipedia
The mineral cobalt is what gives cobalt glass its intense blue coloration. Here's what Wikipedia says on the subject:
Cobalt () is a hard, lustrous, grey metal, a chemical element with symbol Co and atomic number 27. Although cobalt-based colors and pigments have been used since ancient times for making jewelry and paints, and miners have long used the name kobold ore for some minerals, the free metallic cobalt was not prepared and discovered until 1735 by Georg Brandt.
Cobalt is found in various metallic-lustered ores for example cobaltite (CoAsS), but it is produced as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo and Zambia yields most of the worldwide mined cobalt.
Cobalt is used in the preparation of magnetic, wear-resistant, and high-strength alloys. Cobalt blue (cobalt(II) aluminate, CoAl2O4) gives a distinctive deep blue color to glass, ceramics, inks, paints, and varnishes. Cobalt-60 is a commercially important radioisotope, used as a tracer and in the production of gamma rays for industrial use.
Cobalt is an essential trace-element for all multicellular organisms as the active center of coenzymes called cobalamins. These include vitamin B-12 which is essential for mammals. Cobalt is also an active nutrient for bacteria, algae, and fungi, and may be a necessary nutrient for all life.

I love cobalt glass! It looks especially nice displayed where the sun shines on it. Sunflower yellow is a great color to compliment cobalt. Great lens!

Blue is my favorite color, Tammy. My mom loved blue cobalt and I now have a lot of her little blue bottles, which I use for wildflowers. Thanks for reminding me of why I love this glass.
I'm going to be publishing my "Crazy About Blue" lens soon, and am linking to this lens. It's a perfect complement to my theme. Thank you.

I did not know it was a special mineral. How extra special is that. I have one blue glass like the one in your intro. I call it a goblet. DH made fun of me when I bought it because I only bought one. I feel the urge to take it out now...

I can only say, "WOW!" This is a great lens! It covers all of the different types of cobalt glass, and its uses; and it has more resources than I knew existed. I can only hope to do as well with my Blue Cobalt Glass blog. Great work!
