I hope you've all stocked up, or at least you have the Iodine situation figured out ;) because as of today in the U.S. Iodine has become more difficult to obtain, under the guise of "The War On Drugs", but more appropriately by the aggressive strong-arm of "The War BY Big Pharma"
So here's a great recipe to tuck away for some day just in case things get really, really tight here. Our Freedoms are being chipped away daily, so I suggest that you print it out just in case someone somewhere decides to disappear the link on the site! :) (or easier just to copy-paste from here):
>>>"You will need:
Bunsen burner and asbestos square (or a hot plate)
Tripod and tin lid
Beaker, 250 ml
Separating funnel 100ml
Hydrogen peroxide 20 volume
Tetrachloromethane or dichloromethane
1M solution of Sulphuric acid
Supply of ribbon seaweed(Laminaria) - that you can
obtain a a biological supply store or from the
(You must work at a fume cupboard)
1-Collect and dry about a dozen 50cm lenghts of the
seaweed and heat them strongly on a tin recipient
until they are reduced to ash; probably it will
reduce a quite small quantity, about a spoonful.
2- Add to the ash 20 ml of distilled water
in a beaker, and heat the suspension until it boils.
3 - Filter the suspension
4 - Acidify the filtered with Sulphuric acid solution
5 - Add then the hydrogen peroxide solution
You will observe the formation of a brown color due
the Iodine liberation from the iodine ions present
6- Transfer the mixture to a separating funnel
7 -Extract the Iodine with tetrachloro methane or other
solvent. The result is an organic solution of iodine.
8 - In order to obtain crystals , the solvent may be
allowed to evaporate at room temperature, by
placing it in an evaporating dish in a fume cupboard.
It will result crystals of iodine or rather gray-
black brilliant flakes."<<<
