Why choose Euro Glass Heat-Resistant Containers by LocknLock?

  1. It is safe – Material is what makes products different. LocknLock uses heat resistant glass that has a very low risk of breaking itself or spreading fragments (when there is no deliberate impact given) even if it means bearing a greater cost. However, LocknLock persists in heat resistant glass usage in order to create a safe kitchen environment where everyone can safely use their products. It is made from Eco-friendly materials and is BPA-Free.
  2. It is light – Heat resistant glass is more than 10% lighter than tempered glass, lifting a great weight off of users’ wrists.
  3. It is clear – LocknLock oven glass is less likely to become murky. It always stays as clear and pure as the day it was purchased. General glass often shows efflorescence, a phenomenon that turns murky as it contacts with air when stored for a long time. Heat resistant glass, however, has a low risk of efflorescence when in contact with air as there is a low ratio of sodium oxide. It keeps its transparency for a long time.
  4. It heats up less – With its low permittivity, It makes food warmer while the container itself gets less heated when used in the microwave. This is why the bottom glass inside the microwave is made of heat resistant glass rather than tempered glass that heats up very easily as it absorbs electromagnetic waves more than heat resistant glass does
  5. It is heat-resistant – As LocknLock oven glass is made of borosilicate glass that has a strong heat resistance, it can strongly withstand the heat and rapid temperature change. Therefore, you can use it not only in the microwave but also in the oven, dishwasher and it can also be cleaned in boiling water.

A bit about Heat-Resistant Glass 

Heat resistant glass goes through a specialized process that supplements the general glass’ weakness. Therefore, it becomes able to withstand high temperatures. There is a high possibility to be exposed to heat in the kitchen. It is also more than frequent for tableware to be exposed to the use of refrigerator and microwave. Heat resistant glass tableware manufactured by LocknLock is a safety guaranteed product that has obtained KS Certificate (KS L2424) for Heat Resistant Glass Tableware for Oven and Boiling Water from Korean Standards Association (KSA). It can be used in various environments such as 400°C of oven, microwave and freezer. It will not break even if you put very hot food you just finished cooking inside. It can be cleaned in boiling water, dishwasher, dish dryer and steam sterilizer. Heat resistant glass not only uses costly base material (borosilicate) but also goes through a very complicated manufacturing process, decreasing production efficiency which is why it can be dearer than standard glass containers.

Heat-Resistant Glass vs Tempered Glass

Heat-Resistant Glass & Tempered Glass are the two main forms of special glass constructions that are commonly used in tableware & kitchenware. Heat-Resistant glass is strong in thermal shock and is oven safe, while Tempered Glass is strong in physical shock and cannot be used in the oven.
