Canning ovens are extremely dangerous. During canning, the temperature of the product never exceeds the boiling point because the jars are not covered. It is therefore not safe to use low-acid products (e.g. meat, most vegetables) that require a temperature above 212 ° F. Canning in the oven is not a recommended practice.
Short answer: you’re probably not sure. Unlike microwave safety, there is no safety risk of contaminating the food contents of the jars by heating them in an oven. In this case, there is a risk of breaking the glasses.
A boiling water bath shouldn’t exceed 212 degrees Fahrenheit. A pressure vessel provides the temperature of the glasses up to 240 250 degrees Fahrenheit. This temperature can only be reached by steaming under pressure.
Glass jars are designed to hold boiling liquids. When making the jam, add the boiling liquid jam to the jar. Sometimes a jar breaks because it is made of glass and if lost it can break, etc.

Physical safety and food quality: According to the guidelines provided, the jars are preheated in the oven (dry heat), which is not recommended for glass jars. Canned jar makers advise against cooking or canning in jars. It is very risky to break glass.
A sudden change in temperature causes too large a gap between the temperature of the filled jars and that of the canned water before processing. This causes a thermal shock in the glass. The food was too full or the glasses too full. When the glasses are heated in the box, the contents expand and the glass shatters!
