This is a useful and indispensable appendage in confectionary; it
is generally constructed like a cupboard in the recess of a wall.
The walls or sides should be composed of bricks, or wood lined with
tin or sheet iron, to retain the heat, with pieces of wood nailed or
fastened in the sides, about four inches asunder, to form a groove
for trays or boards to rest on, which is necessary for the drying of
lozenges, comfits, bonbons, &c.; there should also be a few strong
shifting shelves made either of small bars of round iron or wood, like
a grating, on which candy pots or sieves may be placed; the grooves for
these should be so constructed as to be capable of inclination so as to
drain off the syrup from the candy pots without taking them from the
shelves; the door should be made to shut close, with a small door at
the top to let out any excess of heat. I have before remarked that it
may be heated by means of the modern stoves. At places where the oven
is heated with wood, furze, etc., a common iron pot or crock with three
legs is filled with the live embers, or it may be filled with burning
charcoal and covered with wood ashes, which is replenished night and
morning, which gives the heat required.
