The bit is 1/8 shank, and I bought it at Lowes. I don't think it is made by Dremel, but it works just fine. The cutting flutes do not go to the end of the bit, but stop about 1/8 from the end. Let's make something.
Sulfur was discovered and known since ancient times. However, it was officially recognized as an element around 1777 by Antoine Lavoisier in France. Apparently, the year and person(s) who discovered sulfur     are unknown to science. We do know it was used up to 2000 years before the birth of Christ by pagan â¦ priests.
Barium was first isolated in 1808 by English chemist Sir Humphry Davy (1778-1829). In 1807 and 1808, Davy also discovered five other new elements: sodium, potassium, strontium, calcium, and magnesium.arium had first been identified as a new material in 1774 by Swedish chemist Carl Wilhelm Scheele (1742-86). The form with which Scheele worked, however, was a compound of barium, barium sulfate (BaSO 4). Barium sulfate is, in fact, the most common naturally occurring ore of barium.
