duction had a value of $134,199 was due mostly to the reorganiza- 

 tion and temporary closing of a few plants whose entire output 

 was sold to the export trade. The remaining production chiefly 

 sold for local consumption remained in about the same condition. 



POTTERY 



For the first time in many years the pottery industry showed a 

 decided falling off in activity and interrupted the steady gain which 

 has marked the course of production. The decrease amounted to 

 nearly 30 per cent, mainly affecting the electrical porcelain business. 

 The table below gives the value of the production for the last three 

 years.

CRUDE CLAY 



Four counties reported a production of crude clays. The greater 

 portion of this output was sold under the name of slip clay and was 

 used mainly in the manufacture of porcelain electric insulators, 

 although a small amount was produced for use in the manufacture 

 of decorative terra cotta and for bonding purposes. Onondaga 

 county produced some red burning clays for use in the manu- 

 facture of red ware. Richmond county made the only production 

 of a white or light burning clay. The total production of crude 

 clays amounted to 7109 tons having a value of $12,424. Of this 

 amount, 4,703 tons with a value of $10,407 were slip clays. 



At present slip clays are used mainly in the production of glazes 

 for porcelain electric insulators, and therefore have to be of such 

 quality that they will fuse at a comparatively low temperature ami 

 in a quiet manner and yield a glaze that will be able to stand up 

 under the extreme condition of a very high voltage current. Such
