Advice on the best warming teapot with durability that won't burn tea.

I’m wondering if anyone has any opinions on what the best warming teapots are?
I’m looking to have several on display at one time and prefer that they be glass.
I was looking at the Concert Teapot from Adagio, but the comments about it’s fragility concerns me greatly.

I’m hoping to find something sturdy, won’t burn the tea, has longevity/is durable, and is appealing in looks.
I hope you experienced enthusiasts can help!
