A woman cleans her gas cooker. She takes the hot plate off the gas rings and turns it over and over, having a good look at it. Man pushes a trolley loaded with these gas plates. Foreman counts them and inspects one. We see how the pattern for the plate is made. Young man shapes the plate. He dusts something with fine powder. The mould is prepared. It is dusted with powder. Then a dark powder is sifted over the top and then shovelled in. A metal tool is used to press down the powder. The man then jumps up and presses the powder down with his feet. Holes are made in the powder and the sides are bashed with a hammer. The mould is emptied and excess powder brushed away. Holes are cleaned out. Bellows are used to clean away powder. Mould is put back together again. The iron is melted.
