Chromated Copper Arsenate

Chromated copper arsenate (CCA) is a wood preservative that has been used for timber treatment since the mid-1930s. It is a mix of chromium, copper and arsenic (as Copper(II) arsenate) formulated as oxides or salts, and is recognizable for the greenish tint it imparts to timber. CCA was invented in 1933 by Dr. Sonti Kamesam, an Indian scientist, and was awarded its first patent (British) in 1934.

CCA is known by many trade names including the worldwide brands "Ascu", "Tanalith", "Wolman", "Permacure" and "Celcure".

Famous quotes containing the word copper:

    He had put, within his reach,
    A box of counters and a red-veined stone,
    A piece of glass abraded by the beach,
    And six or seven shells,
    A bottle with bluebells,
    And two French copper coins, ranged there with careful art,
    Coventry Kersey Dighton Patmore (1823–1896)
