Celeb (S) or Telpe (Q), also known as Ilsa or Giltha, but commonly known as Silver, was a soft, white, lustrous transition metal. It had the highest electrical conductivity of any element and the highest thermal conductivity of any metal. It occurred as a pure free metal and alloyed with mal (gold), as well as in various minerals, such as Silverglint and Greensilver. Most celeb was produced as a by-product of paer, mal, lead, and zinc mining.
