I couldn't leave well-enough alone.
The "crock pot inside something else" concept was less than perfect, particularly in two respects.
1) The water had to be measured in a preheated pyrex measuring cup to ensure a proper leaf/water ratio, which added more complexity and variables.
2) Pouring the tea into the cup was challenging.
So for the second infusion, I used the Crock Pot as the containment vessel, figuring a preheated crock pot full of boiling water would do fine for heat conservation over such a short period of time.
The pyrex measuring cup went inside this (also preheated), so measurement was simple. Just pour water in to the desired marker.
A preheated stoneware saucer was then placed on top, and hot water poured over and under the whole apparatus.
