What is the best container to make ice blocks in?

Question

I need to make some smallish ice blocks in my freezer at home as they last longer than ice cubes. What is the best common container to use in the freezer that will not explode, crack, etc.

styrofoam cup? or will it crack before completely freezing spilling the water?

plastic cup? crack open before completely freezing?

zip lock bag? leave it unzipped (sitting upright of course)

soda can with top cut off?

what do you think would work best? or is there something else I already have at home that would work better?

Answer 1

i use old butter or margarine containers.... sour cream containers.... even tupperware or rubbermaid...... anything will work!!!!

Answer 2

As long as the container has head room !

If you are going to make ice-blocks remember that water when frozen expands. So if you are using a container don't fill it to the brim and allow for expansion by removing air from a bag for instance. The bag won't break then. If the bag is full of water and air as the ice crystals form the ice will crack or break the container.

Use a glass bottle, but don't put a lid on it and don't fill to the brim. I usually use plastic water bottles.

Answer 3

Wile freezing, see if you can get the ice to be moving as it freezs, vibrating plat form or something, that ought to help

Answer 4

I use good old cut off milk cartons, pint, quart or half gallon. Use the size that suits your needs.

Answer 5

It depends on the size you need.
I'd try all and see what you like best.
I'd say the ziplock bags myself but that may be too big for your use, I don't know.

Answer 6

juice cartons work the best ....... we usually freeze the juice ..... then peel off the carton and put it in the punch bowl. Your punch stays cold and it does not become diluted.
