Disappointing, yes? Well, not sure what you expected an indestructible thing to look like. This thing must be from the 1940s or so.
The pot itself is made of some non-magnetic metal, and it was probably all black when it was new, but years of gas stove-top use before I was even born must have burned away the color near the base – I have always known it to have this gradient. It holds 1,5L of steaming hot black tea (preferably Lady Grey or Darjeeling) and has an absolutely drip-free spout. It has a stein-like hinged lid with a glass insert that used to be removable until my dad epoxied it on, untold ages ago. The handle is made of bakelite so it never gets hot, not even when used on a gas stove-top.
The handle is marked with the logo “HØYANG” which sounds Norwegian. If anyone can tell me any details aout that, I would be extremely interested.
(The mug is another contender for this post, by the way. I’ve had it from the late 80’s.)
