Question: Can the teapot be placed on a heating element with a diffuser
Document: The Bodum Assam Glass Teapot is not like any other teapot I have used. No pot pre-heating is necessary; the stainless steel filter does not leave an after-taste; the press-down knob keeps the tea in the pot without making the tea stronger; and (I saved the best for last! ); the spot is virtually no-drip, which keeps my bride from slapping me for being sloppy!
It is only this brand that features a tea press that stops the brewing process when the desired strength has been reached.HOW? The loose leaves are placed on the center inside the stainless steel filter. When you want the brewing process to stop, the plunger pushes the leaves down the bottom of the filter away from the liquid and sealed by a silicon rubber ring surrounding the plunger.
Why you want this pot: It does something no other pot does. It allows you to drink loose leaf tea without having to mess with multiple products. The loose leaf tea is placed in the filter basket, and hot water is poured over the tea. Small holes in the basket allow the tea to steep without allowing any particulate into the tea you will be drinking. When full brewing time is reached, the plunger is pushed to the bottom of the basket, sealing the tea leaves and stopping the brewing process.
I highly recommend this teapot to all tea aficionados, especially those who love loose tea!
Great teapot, easy to use and clean. Makes a super pot of tea at a great price! Every tea drinker should have one!
i love this old fashioned way of brewing tea. it's aromatic and its tasty. this actual teapot is glass and it's pretty. I love the size and i love how it works.
Fits wonderfully on our Copco teapot to keep it warm. Works very well and easy enough to clean. A bit pricey I thought but my girlfriend is happy :)
Having always been a teabag tea drinker, I didn't really know what tea really should taste like.With the Bodum teapot I now appreciate tea for the first time, the pot brews great tea.
This teapot is exactly what I hoped it would be. It looks elegant and holds enough tea in case you have company. It is a lot lighter than I had imagined though, which makes me wonder how fragile it is. Overall, great buy.
I have owned this teapot for 3 years and have used it at least once a week. The teapot is very convenient in terms of cleaning and brewing tea. Some people have had theirs break, and that's understandable. I could imagine it would break if I had dropped it.
Answer: I am not sure about the diffuser concern.  I simply microwave the glass pot with water in it and then insert the metal tea piece.  However, one thing to note is that becasue the metal piece doesn't have holes in the bottom, it only works best if you use at least half full of water as any lower and the tea doesn't get soaked.  Not a good pot for a single cup scenario which I often find myself wanting - so I end up pouring out the rest of it.
