The cons of a ceramic fuse.

Ceramic fuse blown.

Ceramic is very delicate and can easily be smashed. Time delay ceramic fuses tolerate temporary inrush currents without opening which prevents nuisance blowing from equipment startups. If you can see the element or the filament in the fuse you more than likely have a glass fuse. Inside the fuse there is a metal ribbon through which all the current on the circuit passes.
