Which risk dramatically increases during investment casting using a silica-based slurry?

💡 Explanation

Shell cracking is more likely, because thermal stress increases during the wax burnout stage: differential expansion overwhelm's the shell's tensile strength. Therefore, cracking is the chief risk, rather than volumetric shrinkage or binder failure due to environment temperature exceeding ideal material properties.
