Milk Glue...a sticky business...

This is along the lines of the "Little Miss Muffet" rhyme and you get to make your own curds and whey! The good news is that there are no spiders involved...


MILK GLUE RECIPE:

  1. Add 1/2 teaspoon of vinegar or acetic acid to 250 mL warm milk.
  2. Stir and heat (not boil) until the curds and whey appear.
  3. Pour off the whey and squeeze the curd through muslin cloth.
  4. Dry and grind the casein curd into a fine powder and add a little Borax (Sodium Tetraborate).
  5. Add water to the powder when ready to use the glue.

There you have it! A nice strong glue that you can use in an emergency.

You can test the strength of your glue in a number of ways. Try out some of your own ideas or see the suggestion below...

  1. Screw hooks into 2 seperate blocks of wood and then glue the two blocks back to back.
  2. Hang one of the blocks by its hook from a chair leg and hang masses from the bottom block until the blocks come apart.
  3. Make sure you keep a record of the mass (in grams or kilograms) supported before the breaking point was reached.
  4. Compare the mass supported before breaking with glues you can buy from the shop.

Hey! Where did he come from?
