2877 FURNACE Crucible, with improved gas burner. The burner is almost 

 noiseless in its action, and works with a very small gas supply, pro- 

 ducing much more economical results than an.y gas burner heretofore 

 used for the purpose of heating furnaces. Gas supply pipe required, 

 5^ inch. The amount of air and gas used by this furnace is very 

 small. Care should be taken that the right proportion of each is used. 

 A steady blast of air will give the best results. No. 9a or No. lOa 

 Foot Blower is recommended for this furnace; takes No. 00 Crucible.
