Sorry i need your help : i have question . I buy one bottle realistic water . I use some water for small diorama . And the rest in the bottle :They will frozen?

Depends on the product. If it is a two part solution and you have already mixed it, it will cure (harden [freeze]). Usually there is a shelf life (how long a product is expected to stay usable). See what the label directions say.

If you have the product you show in the picture (realistic water) it should not harden in the bottle. You can use what you need and just close the bottle until the next use.

Thanks all for help me

I have had horrible experience with WS realistic water...it loves moisture and even a teeny tiny bit of moisture will ruin it...in fact one of my dio got ruined because of it and the whole water turned white overnight...since then I have thrown it in the bin...have heard casting resin is a much better product or even magic water for that matter...else go for Envirotex...
