Gruesome Tale - don't read if squeamish.
   I used a stove percolator for a few months when my favorite Bunn
   was busted years ago [and wanted to experiment with different
   coffee making methods].

   Coffee percolated for too long, combined with a room temperature
   cobalt blue mug = cooked skin. Thick cobalt blue glass mug blew
   up on contact and super-heated coffee landed on my stomach. I've
   forgotten the actual pain - nature is kind that way - but skin
   did peel off. A thick layer. Skipped right past the blister
   stage. I KNOW what chicken skin in a soup feels like. Shirts
   provide zero protection against super-heated coffee.

   I'm thankful for ice. VERY thankful for a belly that overhangs
   slightly (the THOUGHT of it, omg). Grateful for being a good
   healer and zero scars or evidence of any kind.

   I use only ceramic mugs now. I have not used the percolator
   since.

   And that lady who sued McDonald's over severe burns from
   superheated coffee?

   I relate. People can make fun all they want. But - she was right
   to sue - and I hate even the idea of most lawsuits. Labels on a
   coffee cup don't stop science.
