What do the new "plasticware care symbols" mean on the plastic dishes I have just bought? They are on new Tupperware and on kids' dishes from Kmart.
The Tupperware symbols that I have found listed are:
Arrows forming a triangle = recyclable. A number in the middle specifies the type of plastic used.
A inverted wine glass with water drops = top rack dishwasher safe
A wine glass & a fork = food safe (plastic will not leech into food)
Wavy lines = microwavable (reheating only, less than 100% power)
Oven mitt = oven safe
Snowflake = freezer safe
