in glas-making, a fort of third furnace, intended to anneal and cool by proper degrees the vessels when made. This properly comprehends two parts, the tower and leer. The tower is that part which lies directly above the melting furnace, with a partition between them of a foot thick, in the midst whereof there is a round hole, placed exactly over the furnace, through which the flame and heat pass into the tower; on the floor of this tower the vessels are set to anneal. There are two openings by which the vessels are put into this tower; and after standing there some Lee some time, they are put into iron pans, which by degrees are drawn out all along that part of this furnace, which is properly called the lees; which is five or six yards long, that the vessels may cool by degrees. This lees is continued to its tower and arched all along, and is about four feet wide, and high within. The glaice are cool by that time they are come to the mouth of this, which enters into a room where the glaices are placed are taken out.
