A promotional film produced by Little-King Productions for James A. Jobling and Company Ltd of Sunderland showing the importance and use of Pyrex glassware for home, science and industry. The film also looks at the production process within the Jobling factory taking the viewer through all the processes of making Pyrex from the delivery of silver sand, the key ingredient for glass production, through to the finished product being boxed and stored for delivery. The film opens on a general views looking out across the river Wear at Sunderland with cranes in the distance. The film cuts to a shipyard where two vessels are under construction; one on a slipway the other moored along a dockside. The film changes to show views of medieval stained glass windows in a church followed by windows inside Durham Cathedral including the large circular Rose Window. Laid out on a table are a number of decorative glass products. Close up views follow showing some of these items including a cup and sauce and a traditional coal wagon. On the side of a glass goblet, a view of  an engraving of a sailing ship passing under the Wearmouth Bridge. The image fades to a modern cargo ship moored along the river near to the bridge. In the cargo hold of the ship men work with shovels, they stand watching as a bucket of silver sand is lifted by a gantry crane. From the quayside the crane continues to lift the bucket and the hold of the vessel identified as the Netherlands Coast. The film cuts to show an articulated lorry with a colourful Pyrex livery driving past a a sign across the entrance of an office building that reads  'James A. Jobling & Co. Ltd' .

Credit: A Little-King Production Back in the cargo hold of the Netherlands Coast a man wearing a cap and bomber-jacket watches as another bucket of silver sand is lifted away. In his hand is a glass bottle from which he drinks. Two men on ladders clean the windows at the James A. Jobling office building. The film changes to a show a second woman looking at a different window display of Pyrex kitchenware followed by another woman looking through a microscope. In a laboratory a woman comes over, picks up and looks at a 100ml Pyrex beaker. In a kitchen a woman opens the door of an oven and smells the food cooking in Pyrex bowls. The film changes to a showroom and a man removing a Pyrex bowl from a display cabinet, he shows it to another man. They walk around the showroom and the salesman shows his potential customer various items of Pyrex scientific and laboratory equipment. In a laboratory at Jobling’s a man uses a thick glove to remove a hot Pyrex beaker from an oven and drops it into cold water. The glass doesn’t break. The film cuts to a mechanical knocker hitting the side of a Pyrex beaker. Again, it doesn’t break. Other tests show the glass to be impervious to bacteria and a good electrical insulator. Back in the showroom the salesman opens a cabinet containing various items of glass laboratory equipment and shows a piece to his client. The film cuts to show two large beakers, part of a laboratory set up. A view of the James A. Jobling & Co. Ltd sign outside the entrance of the factory cuts to a large mounds of silver sand inside a storage area at the company factory. Two men stand beside a mixing machine which is adding additional chemical components. Below the finished mix travelling along a conveyor. The film cuts to show the mixture being carried away in a hopper. Around the glass furnace three man stand looking in on the molten mixture. A man uses a piece of coloured glass to examine the mixture in the furnace. Animated sequence shows the tanks where the molten glass is held before a ‘glob’ drops down a shoot onto the factory floor. Blades cut the ‘globs’ onto a turret chain machine which is manufacturing laboratory beakers. Water pours over the cooling glass as it turns on the turret. At the ends of the machine a man removes the beakers placing them on a conveyor. The film cuts to show two women carrying out an inspection of the beakers throwing imperfect ones in a metal bin for recycling. The beakers travel along to another part of the conveyor where another woman applies the Pyrex badge using a machine. The beakers are placed on the conveyor for a final heating in another oven. On the other side of the oven the finished beakers are packaged in cardboard boxes. In a storeroom a woman looks over the Jobling catalogue before removing a box of beakers from a shelf and placing it on her trolley. The film cuts to the elevated glassblowers workshop and two men or gaffers carrying a large gob of molten glass from the furnace over to a table where the ‘Wearside Blower’ blows into an iron blowpipe to expand the glass into a bubble. The exercise is repeated before being dropped into the mould for a 200 litre flask. The blower and gaffers work together to turn the pipe and to continue blowing into it. Finally, the mould is opened and the finished flask is dropped gently onto a trolley and rolled away. General views follow of various gaffers producing individual smaller glass items using a blow pipe. As well as blowing into their pipes the men also spin their pipes around in the air. Many of the men featured sweat profusely and the sequence ends with three of them drinking beer from mugs. The film cuts to the Lamp Working department and a line of men working on a bench with oxygen burner creating complex pieces of laboratory apparatus made from glass tubing. In another part of the factory a machine is making glass tubing with the glass passing along a machine with a rotating ceramic cone. A machine cuts the tubing into a specific section and man checks the items for quality. At the end of the conveyor another man ties one end of the tubing with string. A view follows of a vertical draw-down machine which is also producing tubing. At the top of the machine the fire of the furnace can be seen as the tubing comes out as rods. A woman cuts the ends of the tubing as other women package them for customers in protected cardboard boxes. A views looking along the ends of a stacked pipe of tube cuts to show two men working a mandrill machine. One of the men wearing a bow-tie supervises another to load the tubing in the machine. The film returns to the Lamp Working department where the craftsmen work with the tubing and oxygen burners to create detailed and intricate pieces of laboratory equipment. The film follows one technician as he builds an elaborate piece of laboratory equipment from smaller pieces of tubing. In another part of the factory a woman uses specialist measuring equipment to check the accuracy of the marking on a Pyrex beaker. Another woman performs another test using distilled water and marks with Indian ink the level of the water compared to specifications. On an etching or marking machine a number of waxed glass cylinders spin while at the controls a woman etches the measurements to be written on the glass. The film cuts to show a woman holding one of the waxed cylinders followed by a third who is wiping of the acid used in the etching process. Finally, an Inspector looks over the finished product followed by a view of a ‘Works Certificate of Examination’ confirming the accuracy of the piece. General views follow of large modern education establishment somewhere outside the UK. The film cuts to show a globe spinning stopping at various continents and countries where Jobling glass is used. More views of various buildings and establishments around the world as well as a herd of cattle on a ranch in Australia. A woman walks across Palace Green in Durham past the Durham University Library building. This is followed by a modern building, part of the ICI chemical establishment. Inside a woman wearing an ICI lab coat carries a beaker of liquid nitrogen and pours the content into an elaborate glass laboratory set. A hand turns one of the glass vacuum stop cocks also produced by Jobling. The films shows another experiment relating to the sterility of Pyrex with a coloured liquid being poured into a filter and Pyrex beaker made of borosilicate glass. Other applications for glass are shown including small thin glass resistors used in electrical equipment. The film changes to show a large machine which makes large versions of these resistors for industry. A man stands at the controls of another machine that is welding two large diameter glass cylinders together creating a component part for an industrial plant. A hand flicks through a Pyrex glassware catalogue showing the various illustrations of the standard and custom glassware on offer. In an office two men look over the designs of an industrial installation for the use of borosilicate glass. The film cuts to show piping passing through the site of an acid plant and glass tubing being cooled with water transporting acid around the plant. A view of an Shell-Petroleum oil refinery changes to a man at the controls of a frictional distillation ‘hallshaw’ column. On a farm in a milking shed glass milk recording jars hang from scales as milk pours into them. Above, glass piping transports the milk out of the building. At a coal mine a group of miners come out of a cage after a shift, their Pyrex glass lamp turned on. Two men stop and begin to chat. The film changes to show a man in a laboratory turn the knob on a four-bar water heater. Back in the Jobling factory a woman wears a face mask to spray paint onto a glass beaker. The film cuts to show again the oil refinery seen previously, a small aeroplane taking off from a runway and the Netherlands Coast cargo ship still moored along the river Wear at Sunderland. The film ends on general views of the river Wear and the shipyards along it; in the distance the Wearmouth bridge. End title: Pyrex
