Some operators have said a good deal about the paraffin and the proper
place to secure it. As nearly as can be learned the compounds used in
this country are products of the Standard Oil Company. The paraffin
used in the formulae of this book has an average melting point of 130.
For reducing the melting point of the paraffin mix the paraffin with
the white vaseline of the Chesborough company. If an agent is sold in
a tin stamped white vaseline it should have the name on the tin of the
Chesborough company as this is the only firm having the right to use
this name. Petrolatum albi or white petrolatum is a few cents cheaper
than the vaseline but the difference is of so small an amount that it
is better to use the vaseline rather than packages which may vary more
than the Chesborough product.
