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.
Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who called it dephlogisticated marine acid (see phlogiston theory) and mistakenly thought it contained oxygen. Davy showed that the acid of Scheele's substance, called at the time oxymuriatic acid, contained no oxygen.
