the value of its clay products, has ranged between thirty-seventh and 
fortieth as a brick-producing State. Common brick has been by far the 
greatest item of production, but hollow block, drain tile and face brick 
have also been produced to some extent. 
The development of the common-brick industry has made relative¬ 
ly little progress within the past thirty or forty years and has fallen 
far short of keeping pace with the constantly growing demand for 
structural materials. The reasons for this condition are varied, and 
will be treated in subsequent paragraphs. 
PRESENT STATUS 
Seventeen plants are engaged at present in the production of com¬ 
mon brick. Two of these plants are located in the northeastern part of 
the State, four in the north-central part of the peninsula, and the re¬ 
maining eleven are situated in west Florida. That portion of the State 
which has the greatest demand for common brick and other structural 
materials has only about one-third of the producers within reach. 
Five of the common-brick producers also manufacture face brick, 
two of them also produce hollow block, and one manufacturer produces 
drain tile. For these higher-grade products more thorough preparation 
of the raw clay is made and more careful treatment during the process 
of manufacture is accorded it. In each case, however, the same raw 
materials are used as for the common brick. 
No stoneware is now being produced in Florida. A pottery manu¬ 
facturing jugs, jars, crocks, and similar articles, was formerly operated 
at Pensacola. One brick plant, Barrineau Bros., at Quintette, is 
equipped for the manufacture of turpentine cups. 
Three small potteries are being operated in the State and these 
are engaged chiefly in the production of ornamental articles, such as 
candlesticks, vases, urns, jardinieres, book-ends, and the like. These 
pieces are often made of clays of several different shades, so as to bring 
out a pleasing contrast of colors. Such wares are commonly not glazed 
and are burned only sufficiently hard to enable them to withstand ordi¬ 
nary handling. Vitrification is never reached. Some of the products 
of these potteries are made of blends of several clays which are thor¬ 
oughly mixed and to which a glaze is frequently applied. Many of 
the pieces, both those made from natural clays and those made from
