A decent insulated teapot

[Dilbertian]

Can anyone recommend an insulated teapot? It doesn't need to be a vacuum flask style, just to keep my tea drinkably hot for an hour or two. I'm also not bothered about how it looks.

But what is important is:

1. That it have a glass inner so that it won't taint from any of the different teas I drink.

2. That it be a good pourer. I do not want a teapot that dribbles on my desk!

Volume around 750ml if possible.

Anyone have such a chalice?

I'm hoping someone gets back to you because I'd like one too!

I have this (in black, I call it my tea penguin). Keeps it hot for hours. Holds just under a litre. www.amazon.co.uk/dp/B000NDKRYS/ref=twister_B08CDF4Z62?th=1&_encoding=UTF8&tag=mumsnetforu03-21

Doesn't meet your first requirement but have experienced no tainting with changing teas - just a quick rinse under the tap:

Keeps tea hot for over an hour

Do you change between black tea and herb teas?

I love the look of the penguin (after saying that I don't care about looks) but I'm concerned that so many of the reviews mention either bad packaging so it arrived broken, or the glass inner shattering.
