What is a platform used to hold mortar at a convenient height while being used by the bricklayer called?

The correct answer is a mortar bed, which is specifically designed to hold mortar at a height that is convenient for bricklayers during construction. Having the mortar at this accessible height enables the bricklayer to efficiently scoop and apply the mortar onto the bricks, thereby facilitating a smoother workflow and reducing the risk of back strain from bending down to ground level.

This term is widely used in masonry work to refer to the horizontal surface where the mortar is mixed and stored temporarily before being applied. The mortar needs to be easily reachable to speed up the laying process and maintain a consistent quality in the application.

In contrast, the other options serve different purposes: a scaffold provides support and access to higher work areas but does not specifically hold mortar. A brick ledge is a structural feature on which the bricks can rest but is not primarily intended for holding mortar. A pallet is typically used for transporting or storing materials, not for holding mortar while in use, making it less relevant in this specific context.
