FORNAC'ULA. Diminutive of FORNAX. A small furnace for smelting metals (Juv. x. 82.); or for heating, boiling, or melting anything of a liquid or fusible nature. The illustration (Fornacula/1.1) represents an ancient Roman fornacula in elevation, like one of our coppers, from an excavation near Wansford in Northamptonshire, and was intended for making the glaze employed in a neighbouring pottery, to varnish over the outsides of the earthenware vessels there made. The small cut (Fornacula/1.2), let into the text, presents a transverse section of the copper and furnace, and shows how they were constructed.

2. Fornaculae balnearum. The furnace and flues employed for heating the thermal chamber in a set of baths (Fronton. ad M. Caes. 1. Ep. 2.), which are plainly shown in the annexed engraving (Fornacula/2.1), representing the section of a bath-room excavated at Tusculum; the furnace is seen on the left, with the boilers over it, and the flues extending under the whole flooring of the room towards the right.
