Kinson.

The works at Kinson, near Poole (with a wharf at the Albert Embankment, Lambeth), were established in the middle of the present century, and consisted of twelve kilns with boiler, engine-house, drying-sheds, stables, offices, &c. After a few years they were closed, and so remained until 1867, when the property was purchased and came into the hands of the present “Kinson Pottery Company,” who commenced making stoneware drain-pipes. Shortly afterwards the company introduced the making of terra-cotta goods, in which they have been very successful, and fire-bricks, which they manufacture to a very considerable extent. The estate consists of about twenty-seven acres of freehold land, which is underlaid through its whole area with a thick compact bed of clay, in layers of various descriptions. It is (roughly speaking) of three qualities, about 40 feet thick, lying in nearly equal beds of each description. The quality is shown in the following copy of Herapath’s analysis, taken some years ago, for the original company:—

The above alumina is that portion which is soluble in boiling nitro-caloric acid, and therefore considered as not in combination with the silica.

The productions of the Kinson Pottery, in stoneware, are sanitary and drain-pipes of every description, traps, syphons, and pans, and other articles; they are highly vitrified, strong, and durable, and of excellent quality. In terra-cotta, vases, rustic seats, brackets, garden edgings, chimney-pots, architectural enrichments, and other goods are produced, as are also fire-bricks, arch and wedge bricks, &c. The quality of the terra-cotta is extremely good and durable.
