I am not the authority on glow plugs; however, I did find some info that may help to further your diagnosis.
"To diagnose the cause of your melted glow plug, look at the surface of the plug. If the plug is melted inward, causing one or more hollows in the metal, you may assume that the cause is an open circuit coil. The burns themselves could then be caused by more than one issue; for instance, jump-starting the engine with an open circuit coil, or an overly long current feed caused by a sticky relay.
If your plug is melted from the surface down on the heating element (a small tubelike metal fixture with a rounded tip), you may assume that the heating element was overheated and could not withstand the level of heat. This could be a result of engine damage, dripping, coked or worn nozzles, or a premature injection of fuel.
If the glow plug is melted at the tip of the heating fixture, this may be a cause of a premature injection of fuel into the engine. Another cause might be the reduction of the gap between the plug housing and heating element, causing too much heat to flow from the heating fixture and resulting in the melting of the tip of the glow plug"
Not sure if the info helped any but like I said, I have had little experience messing with them other than a simple change.

Did it melt or crack and come apart? Any chance of another pic?

I dont think so...no raw fuel, it does smoke a little at start up when cold but I believe it to be timing, when warm there is none..
also when starting, when it sets for say 30 minutes it has the romps at any temp..The reason for that (I believe) is the oil feed line for the 2nd HPOP is to high on the resivor and sucking some air...This is also being fixed this week. here is a vid of cold start.. 85f outside, 1st start of the day, truck has been running for appx 5 minutes
