UNFILLED CHIP SOAP.
A very good grade of chip soap is made by employing no filling material whatsoever, but unfortunately the price of this soap has been cut to such an extent that these can not compete with a filled chip. A number of the best soaps of this kind are made from a settled soap using a light grease with corn oil. A soap of this nature is made as follows.
| lbs. | |
| Settled Soap | 800 |
| Sal Soda Solution, 36°-37° B. | 252 |
| Soda Ash | 182 |
If this soap is run into frames it may be stripped and chipped in two days.
