A little experiment showing the importance of reflection as an insulator.

We filled three tea pots with 600 cc boiling hot tea

1) Pot on the left is made of steel but has an enamel coating.

2) Pot in the middle is made of stainless steel with high reflective capabilities

3) Pot on the right is made of ceramic

 


We put the lit on top and waited for the teat to cool down. We removed the bags :)

 

 

 



After a few minutes we see the tea the pots left and right dropped substantially in temperature and the middle is still red hot

 

 

 



Even after four (!) hours we could see and feel that the tea in the stainless steel pot is still warm
