What you will receive •You will receive a 5ml glass vial of 99.8% pure Cobalt metal that it in a granular / chip form. As seen in pictures. • Sweet Stocking stuffer, Christmas gift • Great chemistry gift •Amazing science gift The Facts •Cobalt (atomic number 27) This sample is ideal for element collectors on the cheap or those conducting experiments. •Cobalt is silvery-blue and brittle • Cobalt blue glass beads in a Danish grave 3,400 years old. The same glass is found in ancient Egyptian tombs, including King Tutankhamen's, the researchers reported. The discovery hints at trade connections linking the two far-flung locations. •Cobalt compounds are used In Many things including blue dye. • Supernova SN2014J, an exploding star 11 million light-years from Earth. The supernova emitted about 60 percent of the sun's mass in cobalt-56, the researchers reported in the journal Nature. The isotope has a half-life of 77 days and gradually decays into iron-56. • Cobalt is an essential trace nutrient for health. It makes up the backbone of vitamin B12, which is key to blood formation and the functioning of the nervous system. • researchers in Denmark reported that they'd created a crystalline material that can draw oxygen from air, store it, and then release it as needed. Just 2.6 gallons (10 liters) of the material can suck all the air from a room, the researchers said. Just as iron is an essential ingredient in hemoglobin, the blood protein that snags oxygen from the lungs, cobalt is a key portion of this new material. •This is high quality yet cheap affordable Cobalt Safety / Caution •Keep out of reach from children! •Do not ingest •When working with Cobalt it is a good idea to always have some type of eye protection, mouth protection and gloves on.
