Tetsubin Round Black Cast Iron Teapot vs Baalaka 20oz Glass Teapot

Buy the Tetsubin if you want tea that stays hot and a pot that will outlast everything else in the kitchen. Buy the Baalaka if you want to watch loose leaf or blooming tea steep and need to see the color. The cast iron holds heat far better and feels substantial, but it is heavy, needs hand washing and drying, and cannot go in a dishwasher. The glass pot is lighter and easier to clean, but borosilicate chips and cracks if knocked, and the 4.1 rating from 294 owners suggests a fair number of complaints.

  • Choose the Tetsubin if you brew black or dark tea for one or two people and want it to stay hot through a long conversation.
  • Choose the Baalaka if you brew green, white or blooming teas and want to watch the leaves open and the liquor color.

Prices

  • Tetsubin Round Black Cast Iron Teapot: $69.63 at Amazon (last seen Nov 10)
  • Baalaka 20oz Glass Teapot: $9.99 at Walmart (last seen Nov 14)
  • Difference: the Baalaka 20oz Glass Teapot is $59.64 cheaper than the Tetsubin Round Black Cast Iron Teapot at the latest prices (Nov 10 and Nov 14)

What reviewers say

Baalaka 20oz Glass Teapot

  • 4.1 / 5294 ratings

Ratings average 4.1 out of 5 across 294 reviews, so most owners are satisfied. Complaints tend to center on the small capacity and on glass care rather than on the infuser.

What people mention
  • CapacityMixedOwners note it brews only about one to two cups, fine for solo drinking but small for sharing.
  • Glass buildMixedThe borosilicate glass is praised for taking heat but described as fragile and needing careful handling.
  • InfuserPraisedThe removable stainless steel infuser is called easy to fill and rinse and works with loose leaf and bags.
  • PouringMixedThe longer spout is liked for reach, though some say it drips when poured quickly.

Questions and answers

Which keeps tea hot longer?
The Tetsubin by a wide margin. Cast iron stores heat and releases it slowly, while the glass pot loses heat within minutes and benefits from a tea cozy.
Which is better for blooming tea?
The Baalaka. Its clear glass lets you watch the flower open, and the wide body gives it room. The Tetsubin is opaque, so you would miss the display.
Can I put either on the stove?
Only the Baalaka is rated for stovetop use. Heat water separately for the Tetsubin and pour it in, since direct flame can damage the enamel.
Which lasts longer?
The Tetsubin, if you dry it fully after each use to prevent rust. Glass pots chip and crack from knocks, and some Baalaka owners report exactly that.
Is the glass pot worth stepping up to over cast iron?
Only if visibility or lighter weight matters more to you than heat retention. For black tea and long sessions, the cast iron is the better tool.
How many cups does each make?
Both are listed at 20 oz, roughly two small cups. The Baalaka listing also mentions a 44 fl oz figure, so confirm the size you receive.
