THE GRAMERCY 

 ASBESTOS DRYING OVEN 



This oven fills a long-felt want for a clean and substantially-constructed 

 substitute for the ordinary copper ovens, the appearance of which, after 

 a short time in the laboratory, make them very undesirable. 



Constructed entirely of heavy asbestos wood, with exception of the base 

 and rack for shelves. A removable sheet metal plate, which receives the 

 heat of the burner, forms the bottom of the oven ; the permanent base frame 

 and legs are of cast iron (aluminum finish), making the oven most rigid; 

 while the racks for the shelves, and framework of the door, are of cast alu- 

 minum, which is practically unaffected by laboratory fumes. 



The chamber of the Gramercy Asbestos Oven is i2"xio" and is pro- 

 vided with perforated asbestos shelves which can be placed at any height 

 desired. The door is fitted with an air regulator. A ring gas burner is 

 supplied with theoven,rigidly fitted, but most easily removed when desired. 



Price net, $16.50.
