A short promotional film produced by MacQueen Film Productions for James A. Jobling & Co. Ltd of Sunderland promoting their new product for the catering industry ‘double-tough Opalware’. The film shows the production of Opalware plates in the Jobling factory followed by them being tested against earthenware plates in a laboratory setting. [Opening section missing] The film opens on a white Opalware plate onto which is animated the opening title. Title: James A. Jobling & Co. Ltd makers of ‘PYREX’ oven-table glassware presents A woman’s hand removes the plate revealing another underneath with the next title written on it. Title Opalware The film cuts to show a number of cracked and chipped earthenware plates and cup. In a large kitchen a woman loads a tray of crockery into a washer. The film cuts to show a display of new ‘double-tough’ Opalware plates, cup and saucers and bowl followed by close ups of each item. The film changes to the James A. Jobling factory and ‘gobs’ of molten Opalware glass coming out of a machine and dropping into a turning plate mould. Suction pads collect up the moulded plates placing them onto a conveyor that takes them into a glazing pre-heat chamber to be tempered for heat resistance. The conveyor then takes the plates into a ‘chiller’ which sprays water onto them. At the end of the conveyor two women collect each plate placing them onto a different hanging conveyor which takes them through a final heating process. On the other-side of the oven women take the finished plates from their hooks, package and tape them into ‘Jobling Double-Tough Opalware’ boxes. The film changes to a laboratory setting and a woman testing the durability of Opalware cups by dropping a number of them from a height onto a hard surface. None break. In the next test a nail is hammered into a normal plate shattering it into many pieces. A nail is then hammered into an Opalware plate which only breaks into larger sections. A woman uses a piece of emery paper to scratch the surface of an Opalware plate. She then removes a number of plates from a domestic oven and drops them into sink of water to cool them quickly. Again, the plates don’t break. The handle of an Opalware cup is tested for strength by having a spinning metal ball hitting it. The film cuts to show a man holding an Opalware and earthenware cup in each hand. He uses the Opalware handle to break the handle on the earthenware cup. Finally, a 3” nail is hammered into a block of wood using an Opalware cup which is also used to bend the nail. Back in the large kitchen a woman loads another metal basket of Opalware cups into a washer. A second woman takes the now cleaned cups from the machine. Dye is painted along the edge of a piece of a smashed earthenware plate which is absorbed into it. A man breaks an earthenware plate in half and swabs the edge collecting samples which are placed on a petri dish and then into an incubator. The sample is taken from the incubator and put onto a microscope slide. Under the microscope views of bacteria. The ink test seen previously is given to the Opalware plate but the ink isn’t absorbed. It is then wiped off with a cloth. The film ends on the display of Opalware plates, cup,saucer and bowl seen at the beginning of the film. The closing tiles are shown on another Opalware plate. End title: The End. A pair of hands removes the plate revealing the final title underneath. End credit: Produced by MacQueen Film Organisation
