Non-Spicy/Non-Charif Soaking: Transfers Taste to Utensil/Container

A non-spicy/non-charif liquid or food with any liquid (enough to pour, but that may be even one drop) that sits for 24 hours or more will transfer gender or non-kosher status to its container.
Situation Dairy or meat liquid-containing food is in pareve container.
StatusContainer will become dairy or meat (regardless of intention). 
Examples
  • Milk sitting in a pareve mug for 24 hours or more would make the pareve mug dairy.
  • Chicken soup sitting in a pareve stoneware bowl for 24 hours or more would make the bowl meat.
Note This does not apply to any type of cold glass container and the food and the container remain kosher.
