Some thingus from the Verkade Paviljoen (museum of Verkade - known for cookies, chocolates and some other products) at the Zaanse Schans. It is a machine that produces flat, round wax candles.
To the right is an oven that heats the wax, which is then channeled to this machine, where the wax is moulded in a little round aluminium type holder. To the left is a tray in which these little flat candles are gathered. The reflection in the safety screen to the left, provides an idea of the final product. Every Dutch househould has a good stock of these flat candles somewhere in a drawer. The main use will be to keep stuff like coffee, tea and food warm. The lit candle is put in the cavity of a stand; made of clay, metal or wood and the tea pot goes on top of the stand. The candle is of pure wax, meaning that there are no black soot on your pot, as with candles containing a mix with fat.
The machine is not so big; as you can see, the lens is pointing slightly down. The machine is also working (see moving piston arm) and actually producing wax candles.
