Altar Breadboxes

From the Catholic Encyclopedia

These are made of wood, tin, britannia, silver, or other metal. In order that the breads may not become bent or curved, a round flat weight, covered if necessary with silk or linen, and having a knob on top, so as to be easily taken hold of, is placed on the breads. The cover must fit tightly, so that the breads become neither damp nor soiled. The box for the large hosts is of suitable dimensions. A larger box is employed for the particles used at the communion of the laity.
