TO CRYSTALLIZE GRASSES, SEED-VESSELS, Etc.
Take a large-sized piece of alum, and pour over it a pint of boiling water, letting it stand until the water has taken up or dissolved all the alum it will. If at the end of a few hours any alum remains undissolved, you may be sure the water contains all the alum it can hold in a liquid state, and the solution is called a “saturated solution of alum.”
During the summer, while the grasses are in their most perfect state, select such as you think will look well crystallized, and put them into a vase or wide-mouthed bottle to dry, being careful to spread them well apart, so that they may retain their perfect shape in drying. If the season of grasses should pass before you have a chance to collect them, the season of weeds is always at hand. Any boy, in his wanderings over marsh or mountain, through woods or our quiet village street, during even the coldest winter months, could not fail to see some beautiful sprays of seed-pods crowning many of our most common weeds, which if crystallized, would make a very pretty and acceptable present to mother for the corner bracket, or the shelf which seemed just a little bare before. Having secured your grasses or weeds, both together if you like, and having your saturated solution of alum at hand, lay as many tops of the grasses in a flat dish as will fill it without crowding, then pour the liquid over them, being careful that the parts you wish crystallized are under the surface. Let them lie in this position until well coated with the alum. When finished remove them and put in others. Continue in this manner until all are treated. If only a few crystals are desired they may be obtained by dipping the heads one at a time in the solution and slightly shaking them after each immersion. When all have been dipped, commence with the first and repeat the process. Do this until the crystals formed are as large as you wish them to be.
