Container glass is a type of glass used for the production of glass containers, such as bottles, jars, drinkware, and bowls.
Glass jars are considered microwavable.
Jars are often recycled according to the SPI recycling code for the material. Some regions have a legally mandated deposit which is refunded after returning the container to the retailer. Some recyclers have concerns about possible residue in the jar from the viscous contents.
