Borax is a salt (ionic compound), a hydrated borate of sodium, with chemical formula Na2H20B4O17 often written Na2B4O7·10H2O. It is a colorless crystalline solid, that dissolves in water to make a basic solution. It is commonly available in powder or granular form, and has many industrial and household uses, including as a pesticide, as a metal soldering flux, as a component of glass, enamel, and pottery glazes, for tanning of skins and hides, for artificial aging of wood, as a preservative against wood fungus, and as a pharmaceutic alkalizer. In chemical laboratories, it is used as a buffering agent. The compound is often called sodium tetraborate decahydrate, but that name is not consistent with its structure. The anion is not tetraborate [B4O7]2− but tetrahydroxy tetraborate [B4O5(OH)4]2−, so the more correct formula should be Na2B4O5(OH)4·8H2O. Informally, the product is often called sodium borate decahydrate or just sodium borate. The terms tincal /ˈtɪŋkəl/ "tinkle" and tincar /ˈtɪŋkər/ "tinker" refer to native borax, historically mined from dry lake beds in various parts of Asia. (Wikipedia).

In quantum mechanics, a boson is a particle that follows Bose–Einstein statistics. Bosons make up one of the two classes of particles, the other being fermions. The name boson was coined by Paul Dirac to commemorate the contribution of the Indian physicist Satyendra Nath Bose in developing
