Paint for Blackboards.
Common glue, 4 ounces; flour of emery, 3 ounces, and just lampblack enough to give an inky color to the preparation. Dissolve the glue in 3/4 quart of warm water, put in the lampblack and emery, stir till there are no lumps, then apply to the board with a woolen rag smoothly rolled. Three coats should be given.
Removing Smell of Paint.
Place a vessel of lighted charcoal in the room and place on it two or three handfuls of juniper berries; shut the windows, chimneys, and doors and twenty-four hours afterward the room may be opened, when it will be found that the sickly, unwholesome smell will be gone. Another very simple method is to plunge a handful of hay into a pail of water and let it stand in the newly-painted room.
Paint Remover.
To remove dry paint or hard putty make a saturated solution of caustic of potassa with water. Apply to the paint with a swab. After a short time it will be easily removed.
Staining Wood.
Ebonizing Wood.
Logwood chips8 | ounces. |
Copperas 1/2 | ounce. |
Lampblack 1/2 | ounce. |
| Water, sufficient. |
Boil the logwood for 30 minutes in a gallon of water, and then add the copperas and lampblack. Apply to the wood hot, giving a number of coats. In varnishing ebonized wood a little drop black must be added to the varnish or it will give a brown shade.
