13. Various Recipes and Rusle. 



Black ink for zinc labels. — Verdigris, 1 ounce; sal ammoniac, 11 

 ounce; lamp-black, % ounce; rain water, % pint. Mix in an 

 earthenware mortar or jar and put up in small bottles. To be 

 shaken before use and used with a clean quill pen on bright zinc. 



To keep flower-pots clean. — When the pots are cleaned, soak 

 them a few hours in ammoniacal carbonate of copper (recipe, 

 p. 40.) Soak them about once a year. 



To prevent boilers from filling with sediment or scale.— 1. Ex- 

 ercise care to get clean water and that which contains little lime. 

 2. Blow it out often. It can be blown out a little every day, and 

 occasionally it should be blown off entirely. 3. Put slippery-elm 

 bark in the boiler tank. Or, if slippery-elm is not handy, use 

 potato-peelings, flax-seed, oak-bark, spent tan or coarse sawdust. 

 4. Put in, with the feed-water or otherwise, a small quantity of 

 good molasses (not a chemical syrup), say % pt. to 1 pt. in a 

 week, depending upon the size of boiler. This will remove and 

 prevent incrustation without damage to the boiler. These vege- 

 table substances prevent in a measure, by mechanical means, 

 ihe union of the particles of lime into incrustations. 



Cutting glass bottles. — 1. Pass 5 or 6 strands of coarse packing- 

 twine round the bottle on each side of where you want it divided, 

 so as to form a groove % inch wide ; in this groove pass one turn 

 of a piece of hard-laid white cord, extend the two ends and fasten 

 to some support. Saw the bottle backwards and forwards for 

 a short time; after a minute's friction, by a side motion of the 

 bottle throw it out of the cord into a tub of water, and then tap 

 on the side of the tub and the bottom will fall off. 



2. Fill the bottle the exact height you wish it to be cut, with 

 oil of any kind ; dip, very gradually, a red-hot iron into the oil. 

 The glass suddenly chips and cracks all round, then the upper 

 surface may be lifted off at the surface of the oil.
