Hmm maybe something like this? I have one the 18oz glass infusers("FORLIFE Lucent") that I picked up like 6 years ago from a local tea shop.

FORLIFE Dew Teapot with Basket Infuser, Lavender Mist, 32 oz/946ml https://www.amazon.com/dp/B01ESVMLH6/ref=cm_sw_r_awdo_X3MY36MCFH6C2NMAWA9B

They also have a 68oz iced tea glass pitcher with an infuser basket.
