134 HOW TO KEEP BEES 



REFINING WAX WITH SULPHURIC ACID 



On a small scale this may be done in an agate 

 or porcelain-lined kettle. Mr, Root even advises 

 on occasion th^ use of a large iron kettle. The 

 kettle is filled half full of water, 100 parts to one part

 exposing it in thin sheets to the sunlight. 



ADULTERATED BEESWAX 



Dishonest dealers have attempted to adulterate 

 beeswax with several substances; tallow, paraffine 

 and cerasin being more commonly used. Tallow 

 or other greasy adulterants may be detected by the
