  The book is in major sections.  The first is the layout and processes of a glass factory in general - the layout, how a furnace is built, making pots, moving them.  The second is making glass - calcining, recovering cullet, mixing, and melting. Then there are sections on the use of the glass - Blowing Goblets, Drawing Glass Tubing, Bottle Making, Crown Glass Making, Broad Glass and Plate Glass.  Where needed sections or plans of the furnaces showing differences are included along with a small section on an English glassworks.
  It is obvious, in looking at some of the images and the text, that either Diderot or the editor or both did not have complete understanding of the glass processes, but considering the magnitude of both original and English editions with hundreds of etched images and text for each one, that is not surprising.

Diderot image of broad glass sheet workshop Plate 250 Broad sheet workshop. This version of Diderot does not mention the several reheats that the method would take, but these would be quick with thin glass.  The editor says the sheets "must be fairly small - about three feet by four" but the size on the table looks more like 2x3 feet and the tool image (Plate 252) he is referencing, which has a scale at the bottom, suggests that 40 inches by 20 is more likely.
