The Science Behind Using Glass OTG Accessories

The science behind glass OTG utensils, particularly those made of borosilicate glass, lies in their unique composition. Borosilicate glass is engineered to withstand the rigors of OTG cooking:

Heat Resistance

Borosilicate glass is formulated with a low coefficient of thermal expansion, meaning it can endure high temperatures without cracking or shattering. This property ensures the glass remains intact even in the intense heat of an OTG oven.

Uniform Heat Distribution

Glass has excellent heat conduction properties, ensuring even heat distribution throughout the utensil. This uniform heating prevents hot spots, producing consistent and precisely cooked dishes.


The transparency of glass allows for convenient monitoring of the cooking process without opening the oven door, preserving heat and flavor.

Thermal Stability

Borosilicate glass exhibits exceptional thermal stability, reducing the risk of breakage due to sudden temperature fluctuations.
