Question: Is this teapot viable for open flame gas stoves...?How many oz. does it hold?
Document: I was pretty sketpical about a glass teapot holding up. I use mine on a glass stovetop, and I thought I'd be dealing with cracking and a mess. So far, after many months of use, no issues. I put it into the dishwasher on the top rack and it comes out crystal clear. My kids think it's fun to watch the water boil, and it is interesting to put a tea flower in and watch it open. Otherwise, it's just a teapot!
Gas is a lot slower and I just use the precision simmer stove so the flames do not go up around the pot too much.Yes, the lid will fall off if you want to pour the last drop of water out, and so do every other teapot. I prefer pure glass rather than having plastic/rubber seals to hold the lid. It will last longer at least. The handle seems to be to thin and too long.
I need to use a wash cloth to hold the handle after boiling on the gas stove. As with any handles such as mug handles, the handle is often the fail point because they are often hit by anything else and develop tiny fractures over time. I won't put too much weight on the teapot all the time such as 5 cup, because it's not easy to hold all that weight with one hand on a big round handle.
I bought this to get away from the closed up, metal pot with plastic parts. I had noticed the metalic taste in my tea, and it didn't seem worth it to continue that. This pot is little, so be aware of that. The lid is also glass, so don't expect a tight fit. Hold onto it when you pour or take it off, or you'll have it falling into your cup. It holds about 5 (8 oz) cups of water.
* I use mine on a gas stovetop over medium flame. This has been fine, no issue. * Handle never gets hot, in my experience. * Being able to watch the water boil is actually surprisingly enjoyable! * Very easy to clean, and very easy to see if it needs cleaning. * No problem with it being too fragile, which was an initial concern. The glass appears quite thin, and it's easy to assume it's looking for an excuse to break, but this hasn't been my experience.
It is durable but the glass is not thick like pyrex. I use mine on the gas stove top as a kettle and it is great for that. Flaw is there is no lip or ridge/tab for the lid to at least sort-of stay on while pouring-you always must remember to hold it before you start pouring. My lid broke and I have a plate on top now until I buy another lid. Seems small at first but holds five measuring cups of water without reaching the top.
The full volume is actually 6 cup. Practically you make 4 or 5 cups and should have enough for guests using smaller tea cups.Being all glass, this can be microwavable and dishwasher safe. The box on the listing says can be used on electric and gas stoves but my Munich box didn't have that.I used it on microwave, on gas stove and it happened to fit my coffee maker hot plate exactly.
I purchased the Munich teapot as a gift for my girlfriend. We are both tea enthusiasts and we have used many teapots ranging from aluminum to cast iron before. What we enjoyed about the Munich teapot is that it is glass yet it can be heated on a stove. I have looked for such a product for a long time and most of the stores I have visited (Teavana, Williams Sanoma, etc) do not carry glass teapots that can be used on a stove.
I read many of the reviews before purchasing and knew I wanted a glass teapot that could go from stove to table...this one has the added infuser which makes it so much easier to make a pot of tea. The first time I made a pot, I was cautious on the heat strength just to be certain I didn't crack the glass. It's just like the stuff you used in chemistry class...just a classier "beaker"!
I enjoyed this teapot for many months. The glass infuser worked as advertised, the handle stayed cool, and it was quite handsome. Normally, I would boil water in a separate electric kettle, and brew the tea in this pot. This worked fine, and I washed by hand. Today, I used it on the stovetop for the first time, and it developed a crack stretching across the entire bottom of the pot, and it started leaking.
Answer: Yep, it's usable on open-flame gas stoves. I've been using mine on a gas stove for years with no problems.
