Why does the blender jar break?

Q: Why does the blender jar break?

The glass jars break due to sudden temperature changes . The glass of the blender jug is very thick to avoid breakage, but temperature changes cause expansion in parts of the glass that does not correspond to the previous temperature, causing breakage. To avoid this, it is advisable to adjust the temperature before pouring really hot or really cold liquids. For example, if we are going to make a vegetable cream in the glass by pouring the food directly from the pot, it is advisable to pour hot water first so that the previous temperature of the jar matches with that of the food. The plastic jugs also break due to the food hitting the walls during blending: small bones or seeds thrown at high speed can cause cracks in the plastic of the jug.
