How to make alum crystal<\/h3>\n

Level Elementary<\/p>\n

\"\"<\/h3>\n

Concept of alum crystal<\/h3>\n

There are many pure substances which make the peculiar shape crystals when these become the solid. Let\u2019s make the alum crystal which can do in short period.<\/p>\n

Materials required for alum crystal<\/h3>\n

alums potash (KAl(SO4)212H2O)110g, string, straw, paper, thermometer, pan, plastics container, glass cup, and styrene foam box or cooler box<\/p>\n

Procedure<\/h3>\n
    \n
  1. Put alum potash 80g and water 400ml in a pan. Heat it until all the alum potash is dissolved.<\/li>\n
  2. The solution is poured in a plastic container about 3mm in depth.<\/li>\n
  3. Small crystals are made after a half day. Take one crystal which is good shape and transparent.<\/li>\n
  4. Tie the crystal with the string. Opposite of the string is tied to a straw.<\/li>\n
  5. Wash the dust from the surface of the crystal and the string in water.<\/li>\n
  6. Put the saturated alum potash solution 300ml to another pan.The alum potash 23g is added in it and it is heated again.<\/li>\n
  7. Cool down the solution up to about 40\u2103.<\/li>\n
  8. The solution is put in the glass cup. The crystal is put in it, too. Cover the cup mouth with paper not to enter the dust in it.<\/li>\n
  9. The glass cup is put in the styrene foam box or the cooler box. Leave it for two days.<\/li>\n<\/ol>\n

    Extension<\/h3>\n

    The salt (sodium chloride) makes a cubic crystal. However, it takes several months to make a big crystal in the laboratory. There is salt mine in the Salt Range. The cubic crystals of the salt sticking on the wall can be seen in the mine.<\/p>\n
