At the session of the Society, on the 6th of June, 1850, 



Under the direction of M. Ebelman, the master of the national 

 manufacture of porcelain at Sevres, two young artists attached 

 to that establishment made experiments before the Society of a 

 new process, to be a substitute for the common way of moulding. 



It consists in pouring the liquid porcelain matter (called bar- 

 botine,) into moulds made of plaster which absorbs water with 

 great avidity. The porcelain paste which remains fixed to the 

 sides of the plaster mould, is afterwards easily detached. In this 

 way they mould medallions and sheets for painting. By this 

 means thej obtain very thin cups by pouring liquid porcelain 

 in paste into plaster moulds of suitable shape. They have suc- 

 ceeded in overcoming a mueh greater diflBculty — that of ad- 

 ding handles to the cups, of the most delicate kind, and every 

 species of ornament. These handles are hollow. They are cast 

 in halves, and then united. The barbotine first flows very clear 

 and liquid, in order to penetrate and perfe«tly fill up all the 

 details of the ornament ; afterwards they pour in two other beds, 

 thicker than the first. The operation, made under the eyes of 

 the Society, lasted about a quarter of an hour. They soldered 

 the handles with porcelain paste,' after having wetted with gum 

 water the points of contact in the cups and the handles. The 

 Society witnessed these operations with great interest, and de- 

 sired the president to express to Mr. Ebelman their warmest 

 thanks. 



Chairman. — Thinks the difficulty here is the want of cheap 

 labor. 



Judge Van Wyck. — The same, doubtless, as to soil. 



Mr. Youman. — Even if the Chinese should come here they 

 will find higher priced labor. 



Judge Van Wyck. — Brazil has succeeded to some extent for 

 many years. 



Mr. Youman asked whether the Apatite of Jersey or Lake 

 Champlaiu is yet much in the market.
