Sulfur

Elements main page

Sulfur, symbol "S", atomic number 16, is a yellow non-metal which is not generally very commonly used pure, but it's compounds have a very wide range of uses. If you heat pure sulfur it liquifies into a red liquid, then burns in air to make sulfur dioxide, a very choking gas.

Sulfides have uses in the making of rubber, and zinc sulfide glows in the dark if activated.

Pure sulfur sometimes occurs in nature as large vivid yellow crystals, which are prized by mineral collectors everywhere.

These are my samples!

Cadmium Sulfide Photoresistor

This unusual electronic component consists of a small length of cadmium sulfide applied to a ceramic surface, which acts as a resistor in dim light, but conducts pretty well in bright light.

These are commonly used as light switches, for example, if you want to turn on a street light after dark, and in those little solar lights you can stick in the ground all around your house and driveway.

This one is unusual in that it's HUGE, and you can clearly see the yellow color of the cadmium sulfide, which is also used as a yellow pigment in paints.

Sulfur Shot

Most elements are available in shot form, such as tin, lead, bimsuth, even some non-metals like tellurium, but sulfur is one I'd never seen as shot.. So I came up with the bright idea to pour hot molten sulfur into water to make it myself. At first I got a cruddy mess at the bottom of the glass, but once I chilled the water by putting it in a freezer for awhile, it did actually form fairly nice shot. Pretty useless, but hey, so are a lot of things I collect for the sake of rarity.

Sulfur Bloblets

I'm not sure what else to call these strange formations, which are oddly enough pure sulfur, simply made by pouring molten sulfur (A touchy process, too much heat and you have beautiful blue flame and sulfur dioxide gas) into cool water.. I was trying for shot but it didn't work too well this try, it was amazing to watch though.

Antique Sulfur

This is a small jar of sulfur, made by "Perfect Chemical Co.", possibly as far back as the 50s. Note on the lid it says 25 cents, which is probably what the sulfur is worth, but you won't find ANYTHING that cheap these days.

Sulfur Powder

Small sample of sulfur powder, I have 10 POUNDS of this I bought from a friendly feed store back when I lived by Pittsburgh where cows where everywhere... Apparently sulfur is supposed to be mixed in with some kind of cow food, even the guy who sold it to me didn't know how or why. We told him we were making rockets and he only made it cheaper... Won't see that behavior much anymore.
