Boral Bricks. Created the “old-fashioned way,” formed in a sand-dusted wooden box, no two bricks in the 17th Century Bricks collection are exactly alike. The solid bricks feature slight irregularities and a softer shape that mimics the 17th century look. Color variations and a velvety texture offer aesthetic and tactile appeal. Renewable sawdust waste materials are used in the firing process, and half of the maker’s brick production is accomplished with alternative fuels. 800.526.7255.
