GLAZING. 



The females c and D are employed in detaching from articles 

 which have been dipped the parts of the glaze which are redun- 

 dant. Thus c scrapes off, with a bladed tool, a portion of the glaze 

 where it is too thick, or where it remains attached to the surface 

 in round drops called tears. The other, D, removes with a brush 

 or a piece of felt the glaze from the circular ring at the bottom of 

 a plate, that being the part on which it stands when placed in 

 the oven. If this precaution were not taken, the plate would

adhere to the oven by means of the portion of glaze on this circular 

 edge when vitrified. 



"When the articles are thus prepared, they are put into an oven 

 where they are exposed to a temperature which vitrifies the glaze 

 upon their surface. 



It is necessary that the glaze thus applied to the article should 

 be such as will vitrify at a temperature lower than that which 

 would soften the paste of which the article is made, and thus 

 deform the article itself. 



In the figure are seen several tools and utensils used in the 

 process of glazing. Thus g is the wooden grating upon which the 

 art tele is left to drip after being withdrawn from the glaze ; t is a
