ENGRAVING FLUIDS.
We here give a formula for making an etching fluid, to be used in marking razors, shears and other steel tools.
FORMULA.
| Bluestone | 1 | ounce |
| Table Salt | 1 | ounce |
| Water | 6 | ounces |
Directions.—Cover blade or plate with soap or varnish, and then with etching needle or common pencil write the name or letters desired, being careful to score or scratch through to the metal. Then fill the traced lines with the fluid and let it remain five minutes. The fluid will corrode the metal in the lines thus laid bare. Therefore when the covering and acid are washed off the lettering will remain.
Be careful to wash promptly and dry thoroughly.
BLACK HEADS.
What are known as black heads are generally found in the skin of people who are addicted to the use of much hog meat. Such people are also as a rule, rather careless, to say the least, about bathing their faces. A hint to the wise will be sufficient. Let them not be afraid a rough towel will scratch them. I give below a recipe highly recommended.
FORMULA.
| Alcohol | 4 | ounces |
| Boracic Acid | 2 | drachms |
| Distilled or rain water | 1½ | ounces |
