Also available are firebrick "splits" which are half the thickness and are often used to line wood stoves and fireplace inserts. The dimensions of a split are usually 9 in × 4 + 1 ⁄ 2 in × 1 + 1 ⁄ 4 in (229 mm × 114 mm × 32 mm). [3] Fire brick was first invented in 1822 by William Weston Young in the Neath Valley of Wales.
