When soldering a fixed partial denture before porcelain application, the greatest risk of failure is:

Overheating

Explanation:

Soldering is such a process in which we join two or more items together with the help of heating. In this process, the joining material usually a metal is heated up to its melting point and then is inserted between the two items to be joined.So, when soldering a fixed partial denture before porcelain application, there is a greater risk of overheating as the process of soldering involves the formation of oxides. The rise of temperature is risk associated with the soldering a fixed partial denture before porcelain application.
