308 CLAYS AND CLAY INDUSTRY. 



introduction of Beileek porcelain by Messrs. Ott & Brewer. Later 

 a superior quality of hotel china was introduced by the Green- 

 wood Pottery Company which at the present day has secured a 

 wide and enviable reputation. The production of a good quality 

 of sanitary ware was another important development, and the 

 manufacture of this has grown, so that at the present day, Trenton 

 is without question at the head of this branch of the pottery in- 

 dustry. The Trenton potter has not stopped, however, at a satis- 

 factory body, but makes successfully the most complicated forms 

 of sanitary appliances, much of this ware being exported. 



Still another important advance has been ma.de in the manu- 

 facture of fire-clay bath tubs and sinks which are made in one 

 firing - . In this line of work Trenton also> leads, having the largest 

 single pottery in the world, devoted exclusively to the manu- 

 facture of these goods. The product comes into successful com- 

 petition with foreign wares. 



Trenton is the most important potting centre in New Jersey, 

 and in fact is one of the two great pottery centres of the United 

 States, East Liverpool, Ohio, being the other. The wares pro- 

 duced at Trenton include table and toilet wares, sanitary wares, 

 ornamental articles, druggist supplies, door knobs, electrical goods, 

 hardware trimmings, washtubs, bath tubs, sinks, etc. The 

 statistics of production are given on another page. 



Trenton has assumed its importance as a pottery centre, not 

 because of a wealth of raw materials in the immediate neighbor- 

 hood, but rather because of its central location as regards trans- 

 portation facilities, for probably the only New Jersey raw ma- 

 terials used by most of the Trenton potters are sagger and wad 

 clays. The others, such as kaolin, flint and spar, are all brought 

 from other states, as is also most of the ball clay. The sanitary 

 ware branch of the potting trade is the one that has developed 

 most rapidly in Trenton, so that more of this class of ware is 

 now produced there than at any other locality in the United 

 States. 



At other localities. — Outside of Trenton the manufacture of 

 pottery is carried on at scattered points in the State, the product 

 consisting usually of either red earthenware or stoneware. Sani-
