Dishwasher and dryer safe

Made of heat-resistant glass, so it can be disinfected with boiling water for hygiene.

Microwave and oven safe

Heat resistant glass reduces shrinkage by approximately 1/3 of heat when compared to other glass.So it is resistant to sudden temperature changes and can be placed in the microwave

Heat resistant glass is heat-resistant glass, but not tempered glass, so it is not impact resistant.Crash or drop may damage

What is the temperature difference between heat-resistant temperatures?

This product does not indicate the temperature it can tolerate.Hold glass part (except parts) in a constant temperature temperature for 30 minutes, remove at a place where the glass is held at an even temperature, immediately immerse in cold water for 1 minute to indicate a temperature difference of unbreakable glass.

In other words, the higher the temperature difference, the better the glass is heat-resistant.

Tips to maintain glassware for a long time

Glass is broken by tensile stress.In order to extend the life of glass products including heat-resistant glass, it is very important to avoid scratches as possible without clapping metal, bumping onto hard objects such as ceramics, or rubbing with abrasive sponges.

Most substances, including glass, will expand and contract when heated and temperature rises.Heat damage is most often caused by sudden cooling or sudden heating.The heat-resistant glass is very small in inflation and contraction due to heat, so each stress produced by this expansion and contraction can be reduced and resistant to heat.

When the glass breaks, it is always damaged from scratches on the side of the tensile stress as a starting point

Stronger scratches (deep) will break down with less stressScratches will grow with repeated use (deeper) and glass strength will decrease
