Glass kitchenware is suitable for many kitchen tasks: baking, mixing, chopping, serving and storing food. The material is transparent, generally absorbs fewer odours or colours than some plastics and looks presentable straight on the table. However, the term “glass” alone says little about how a product performs in everyday use.
A product may be suitable for the oven but not the dishwasher. A storage container may have a glass base, while its lid must not go in the microwave. And a spacious-looking bowl in the product photo may actually be too small for your portions. So pay particular attention to these three common pitfalls.
Borosilicate glass is often mentioned for its performance when temperatures change. That does not automatically mean every product can go straight from the fridge to the oven without restrictions. Always check the stated suitability for the oven, microwave and freezer, and follow the instructions.
For example, avoid pouring boiling water directly into cold glass. A sudden change in temperature can create thermal stress, which may cause the glass to break.
A glass oven dish with a lid will often have different usage instructions for each component. The dish may be oven-safe, while a polypropylene lid must not go in the oven, microwave or dishwasher. Also check silicone rings, metal clips and wooden stands separately.
This is particularly important with a glass storage container with a lid. A tightly fitting lid is useful for storing food, but it must not be heated without checking that it is suitable.
A capacity of 1 litre is not the same as a dish that comfortably holds a full meal for several people. Check the length, width, height and usable capacity. Also make sure the dish fits in your oven and has enough space around it.
The shape also matters when baking. A shallow glass pie dish is suitable for pies, quiches or thin oven dishes, while a deeper oval dish is better suited to lasagne, gratins or leftovers for the following day.
For everyday baking and food storage, the following details are relevant:
According to the product information, the 5five Keepeat oval dish is made from borosilicate glass, is suitable for oven use up to a maximum of 400 degrees, and can be used in the microwave and dishwasher. The polypropylene lid, however, must not go in the oven, microwave or dishwasher. Always check the current instructions on the product page before use.
“Dishwasher-safe kitchenware” does not always mean that every part of a set is dishwasher-safe. Pay attention to:
A glass storage jar may be suitable for use in the fridge, but that does not make it suitable for the oven or microwave. For PURECOOK storage jars, it is recommended that the glass jar is carefully cleaned in the dishwasher and that the silicone ring is washed by hand. The manufacturer also warns against pouring boiling water into cold glass and against using the jars in the oven or microwave unless this is expressly stated.
For one or two people, a small mixing or chopping bowl is often sufficient. If you regularly prepare meals in advance, a dish of 2 litres or more will be more useful. When choosing kitchen accessories, also consider storage space: round bowls can take up a lot of room, while stackable containers or nesting models make more efficient use of space.
For electrical models, motor power, bowl capacity, speed settings and cleaning are the most important factors. A glass food chopper is practical for onions, herbs, vegetables, nuts or smaller quantities of meat. Keep the maximum filling level in mind, and always remove the blades from the bowl before cleaning.

We have compiled a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
No. Only products that expressly state they are suitable for oven use should be used in the oven. Also check the maximum temperature and remove any plastic lid before placing the dish in the oven.
This varies by component. The glass container may be dishwasher-safe, while the lid, silicone ring or clips may need to be cleaned by hand. Follow the care instructions for the specific model.
Its lifespan depends on the material, use and care. Glass can remain usable for a long time as long as it is not dropped, does not develop cracks and is not exposed to sudden changes in temperature. Regularly checking for damage helps you continue cooking and storing food safely.
