Potassium is the second least dense metal after lithium. It is a soft solid that can be easily cut with a knife and has a slow melting point. Potassium turns from silvery to grey when exposed to air and must be stored in brown glass bottles under paraffin oil to prevent reaction with water and maintain its color. Before being recognized as an element, potassium carbonate was used to make soap by mixing it with animal fat, extracting it from wood ash through boiling water concentration.

2. POTTASIUM IS THE SECOND LEAST DENSE METAL AFTER
LITHUIM. IT IS A SOFT SOLID THAT HAS A SLOW MELTING
POINT AND CAN BE EASILY CUT WITH A KNIFE.
FRESHLY CUT POTTASIUM IS SILVERY IN APPERANCE
THOUGH BEGINS TO
TARNISH TOWARDS GREY
IMMEDIATELY AFTERBEING
EXPOSED TO AIR.

3. POTTASIUM IS KEPT IN
BROWN GLASS BOTTLES
UNDER PARRAFIN OIL TO
KEEP ITS COLOUR AND TO
STOP IT FROM REACTING
WITH ANY WATER NEARBY.

4. BEFORE POTTASIUM WAS
RECOGNISED AS AN ELEMENT
POTASSIUM CARBONATE WAS
MIXED WITH ANIMAL FAT TO
MAKE SOAP. THE CARBONATE WAS
EXTRACTNG WOOD ASH WITH
WATER BEFORE CONCENTRATION
OF BOILING!
