MUFFLES, Opaque Fused Silica, see note below. 



Note: Owing to the great variety of sizes and shapes of muffles in use throughout the coun- 

 try, we have made no attempt to offer a complete list in this catalog. We shall be very 

 glad to quote prices upon request upon muffles made of alundum, clay or silica. As it is very 

 important that the muffle shall fit the space for which it is ordered, we urge that orders or 

 requests for prices be accompanied by (1) a list of dimensions both outside and inside, (2) 

 a statement as to whether both ends are open or one closed, and (3) a sketch showing the exact 

 shape of the cross section of the old muffle.
