Shatter resistant tea carafe/pither/pot

First let me explain how I make tea.

In the morning I take a pot of boiling water and pour it into a carafe. I let the the water sit for a minute. I then pour the tea into an old pot from a coffee maker, put the tea bags in the original carafe and pour the water over the tea, let steep. Pour into another large pot to dilute with water. Over the day I either nuke the tea or I pour it over ice when I want some.

For more then ten years I had a nice pitcher ( from Ikea ) for this.till one morning it shattered. Now a second pitcher shattered after about two months.

What should I get now. I would prefer for obvious reasons that it did not shatter. I do not want to use a stainless steel pot because I notice stainless steel leaves a taste when I boil water in it. The initial amount of tea I make is approximately one quart, and I have not found a measuring cup that large.

Can anyone make a suggestion?
