: 18 15, Bezirius was engaged in analyzing an ore produced by thorium in Fallum, Sweden, and found a new metal oxide very similar to zirconia. He named the new metal Sorin after the ancient Nordic Thor, and gave it the Latin name Thorium and the symbol Th.

Because Bezirius was an authority in the chemical field at that time, chemists recognized it. However, after 10 years, Bezirius published an article saying that this new metal called thorium is not new, and the ore containing it is only yttrium phosphate, and he himself withdrew the discovery of thorium.

At 1828, Bezirius analyzed another kind of ore, which was found in the black granite produced in Lefeng Island, southern Norway, and found an unknown element in it. Still named after thorine. It is now clear that the main component of this ore is thorium silicate. So thorium was first named and then discovered.
