FORLIFE Mist Glass Ice Tea Jug , 50-Ounce, White

Am I correct in assuming that since there is not a separate piece for loose leaves that may be removed, the tea steeps till al the liquid is gone?

How wide is the top opening at its narrowest point? Is the lid water tight or would liquid leak out if the pitcher were tilted too far?

Will this pitch stand up to boiling water?

Can the strainer be removed, without compromising the effectiveness of the pouring? And does the lid seal the top (that is, is it spillproof)?
