Judging from the ingredients list, beef stew in glass jars will not be fried. Because glass is a very stable substance, it will soften when heated at high temperature, but it will not burn and explode. This means that even during the stewing process, the glass jar will not explode due to the increase of internal pressure or other factors.

Judging from the production steps, the process of stewing beef usually needs to be heated for a period of time, which may increase the surface temperature of the glass jar. However, due to the poor thermal conductivity of glass, this temperature change usually does not have a fatal impact on glass jars. Of course, it should be noted that if the glass jar is directly heated by an open flame, the flame may heat the glass jar and cause the glass jar to break. Therefore, in the process of beef stew, it is suggested to use indirect heating, such as stewing in a saucepan or oven, to avoid this situation.

Generally speaking, as long as proper heating methods are paid attention to during beef stew, the glass jar will not explode.
