I'd be afraid to do that - when liquids heat up, they expand. In glass I would think, and I could be wrong, that if it were sealed, you'd run the risk of broken glass - if the bottles are open maybe..... not sure how hot is too hot for juice though.
my bad, a lifetime working on "stove tops" got me through some preliminaries. i bought some candles from the dollars store and put them in a pot to melt the candles. then i covered then with water and brought the heat up. i let it cool and skimmed off the wax from the top, and then repeat. then i scrubbed them in hot soapy water. (just making sure the wax and the vanilla from the candles was gone.
absolutely, the nice, thick, glass bottles will be uncovered, and i will be bringing the temperature up slowly. obviously, to some degree or another, people have applied heat to juices to quicken the steeping stage, so it's just a matter of how much can you apply.
from my point of view, steeping juice in a container that is the same size as the juice doesn't make sense. when you shake it, there's no room for the molecules to fly around and crash into each other. i'll have plenty of room for expansion, but the room is really so that when it cools and i shake it, there will actually be some movement of the juice.
twill be an interesting experiment!
