 Meker Crucible Furnace, Type ], without air blast. 



2923-2925 



This type of furnace is very useful for a large number of purposes since in it temperatures of from 1050 C. to 

 1100 C. can easily be obtained without the use of an air blast. The crucible, which is fitted with a lid, is supported 

 I at three points only and the flame therefore completely envelops it. The No. 4 J furnace uses an ordinary No. 4 

 ! burner, and the No. 5 ] a. No. 5 burner. A special durable fireclay crucible is included with each furnace. We 

 can supply at a slight extra cost, crucibles of Berlin porcelain. For obtaining the highest temperatures quickly 

 these are useful, being thinner than the fireclay crucibles.
