Flower pots

Safety-match strips arranged for decorative purposes in the form of flower pots are especially undesirable items, since an accidental ignition causes a dangerous flaring of many matches at one time. 

Example 4.8 A small flower pot as shown in Fig. 4.56 is to be thermoformed using negative forming from a flat plastic sheet 2.5 mm thick. If the diameter of the top of the pot is 70 mm, the diameter of the base is 45 mm and the depth is 67 mm estimate the wall thickness of the pot at a point 40 mm from the top. Calculate also the draw ratio for this moulding.

Many of the materials used in the most advanced technologies are made from one of the oldest known materials, common clay. Most clays used commercially are oxides of silicon, aluminum, and magnesium. China clay contains primarily kaoli-nite, a form of aluminum aluminosilicate that can be obtained reasonably free of the iron impurities that make many clays look reddish brown, and so it is white. However, other clays contain the iron oxides that cause the orange color of terra cotta tiles and flower pots. 

The quantity of these materials is relatively small compared with the amount of waste high-density poly(ethylene) produced each year. Containers made from HDPE are widely used for detergents, oil, and antifreeze, and enormous amounts of material are used in disposable applications aimually. In principle recycled poly(ethylene) could be used for drain pipes, flower pots, dustbins, and plastic crates. The problem remains, however, that economics do not favour recycling of these polymers and in the absence of Government intervention little or nothing can be done to alter commercial attitudes towards recycling.

What to do Earwigs do not usually travel far, so clearing up debris where they might hide, and trapping, can make a local difference. Trap earwigs in overturned flower pots stuffed with straw and placed on top of a cane, or in lengths of dry fava bean stalk, or in a "lacewing hotel" (see pp.112-113). 

HDPE resins are also used to make flower pots, pipe, bottle base cups, pails, and drums. 

Genpak, a plastic products manufacturer, and Mobil are in the process of opening and operating one of the first plants to recycle polystyrene foam items such as food containers, cups, and cutlery. The materials are being collected from Massachusetts schools and institutions by New England CRInc, a major reclamation firm and recycled materials end-use manufacturer. The plant has a capacity to recycle 3 million lb per year of polystyrene resin, which will be reused by the companies or sold to producers of insulation, fence posts, and flower pots. The new company is expecting a profit by 1992. 

General-purpose polystyrene is extruded either clear or embossed for room dividers, shower doors, glazings, and lighting applications. Injection molding of impact polystyrene is used for household items, such as flower pots, personal care products, and toys. General-purpose polystyrene is used for cutlery, bottles, combs, disposable tumblers, dishes, and trays... 

Imagine a life without clay objects no ceramic dishes, bricks, or flower pots. In addition, we would have no beautiful ceramic art objects to enjoy. Our lives are richer because someone realized that a material found in the ground could be fashioned into functional and beautiful objects.

Assemble an arrangement as shown in Fig. 105, using for this purpose two clay flower pots or chamotte crucibles of a different size with a hole in their bottom. Fill the space between the pot walls with dry sand. Insert a carbon electrode through the bottom holes of the pots and fasten it in a clamp. Triturate several pieces of carbon for arc lamps in a mortar. Prepare a similar powder from a natural chalk, better from calcium oxide. Weigh 8 g of calcium oxide and the calculated amount of carbon and thoroughly mix them. Spill the mixture into the inner pot of the arrangement and lower a second upper carbon electrode so that it almost contacts the first one. Connect a rheostat for 40 V. Switch on the current, which should be 10-15 A. Carefully move the electrodes apart, trying to obtain the maximum...
