How to shoot high-temperature objects in photography

Photography is painting with light, so it is not directly related to the temperature of the object being photographed. According to the shooting results you mentioned, it is assumed that you are using a stupid camera or a fully automatic camera, so the camera is not very accurate when measuring light. I suggest you use a manual camera or a manual camera, and try several exposure combinations. If you are not using a digital camera, remember to take a picture and make a record (exposure combination).
