Cobalt's atomic number is 27 and its symbol is Co. Cobalt is often synonymous with the color “Cobalt Blue'', however, pure cobalt ranges from a lustrous silver to dark grey color. The blue color that is associated with cobalt is the result of cobalt and halogen gas compounds. Cobalt gets its from German miners that would refer to blue cobalt-containing ore as “kobold ore” which is German for “goblin ore”. Cobalt compounds have been used as dyes since 1400 BC to color glass, glazes, and ceramics. In modern-day industries, cobalt is used in lithium-ion batteries, wear-resistant metal alloys, and as a catalyst for drying oils.

Safety

We get asked about the radioactivity and overall safety of the periodic tables/cubes from time to time. These are legitimate concerns and we wanted to address those concerns here. Although there are several elements in the cubes that are dangerous or toxic, the acrylic and glass ampules make the products safe to handle and store.

The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding a radioactive element in one of our Lucite Acrylic displays.

Care Instructions

Wash with mild soap or detergent and lukewarm water. Use a clean, soft cloth, or sponge. Rinse and blot dry with a damp cloth or chamois.

*Never use abrasive cleaners, household cleaners, window-cleaning fluids, scouring compounds, gritty cloths, or strong solvents such as alcohol, acetone, carbon tetrachloride, etc.*

To maintain the brilliant luster of acrylic, wax and occasionally with a quality grade of automobile paste wax (NOT A CLEANER WAX COMBINATION.) Apply a thin coat with a clean, cotton flannel cloth. Then wipe with a clean damp cloth. NEVER USE HOUSEHOLD SPRAY WAXES.
