 emery as instructed. 



To Clean Glass. First wash well with a soft sponge, using clear 

 water and squeezing the sponge as dry as possible. Then dip the damp 

 sponge in whiting and rub over the surface of the glass. When dry 

 rub clean with a soft cloth. 



PASTE, GLUE, AND MUCILAGE. 



Paste, That Will Keep. Dissolve a teaspoonful of alum in a 

 quart of warm water. When cold, stir in as much flour as will give it 

 the consistency of thick cream, being particular to beat up all the lumps; 

 stir in as much powdered resin as will stand on a dime, and throw in 

 half-a-dozen cloves to give a pleasant odor. Have on the fire a teacup- 

 ful of boiling water; pour the flour mixture into it, stirring well all the 

 time. In a very few minutes it will be of the consistency of mush. Pour 

 it into jars and when wanted for use it can be readily thinned with 

 water. 



lyiquid Glue. First soak in cold water all the glue you wish to 

 make at one time, using only glass, earthen, or porcelain dishes; then by

 ounce of white turpentine is to be added. At the same time a very thick 

 glue is to be kept ready, mixed with a little isinglass. The solution of 

 the resins in alcohol is to be heated to boiling in a glue pot, and the glue 

 added gradually with constant stirring, so as to tender the whole mass 

 homogeneous. After the solution is strained through a cloth, it is ready 

 for use, and is to be applied hot. It dries quickly and becomes very 

 hard, and surfaces of wood united by it do not separate when immersed 

 in water. 



Glue as Mucilage. Take of isinglass and parchment size, each 

 one ounce, sugar candy and gum tragacanth, each two drams; add to 

 them one ounce water, and boil the whole together till the solution ap- 

 pears (when cold) of the consistency of glue; then pour it into any form 

 you please. If this glue be wet with the tongue, and rubbed on the 

 edges of paper, silk or leather that are to be cemented, they will, being
