Tuckpointing was a way of achieving a similar effect using cheap, unrubbed bricks; these were laid in a mortar of a matching colour (initially red, but later, blue-black bricks and mortar were occasionally used) and a fine fillet of white material, usually pipe clay or putty, pushed into the joints before the mortar set.
Tuckpointing was a technique to achieve a similar effect by using unpolished bricks; these were set in mortar of matching color (originally red but sometimes blue-black bricks and mortar were used) with a thin line of fine material, typically pipe clay or putty, inserted into the joints before the mortar hardened.
