I recommend mending Bakelite only with Cryogenic...Chrysalids...Crannberries...Cyanoacrylamide...Oh, you know - CrazyGlue!
I am not kidding. The mend ends up forming a bond stronger than the surrounding material, much like Hot Hide Glue acts with wood to wood repairs. Crazy Glue bleeds into the micro pores of the Bakelite without adding an extra layer between the fragments, which is the big problem with any other adhesive, including china weld. Unless you have access to a Museum's Restoration Shop jigs and tools to hold the pieces in precise alignment The fragments will not fit together perfectly and the repair will be lumpy.
Adhesives like Epoxy, etc, are very difficult to remove after the fact - ask any China Repair Shop - whereas a rubber based glue removes easily but doesn't hold very well. White glue is White glue and should only be used for Crafts. Wallpaper paste is for wallpapering and Hot Hide glue is for furniture.
Test fitting the Bakelite Fragments it is easy to see how perfectly the pieces must be made to fit.
Doug, I would repair your Bakelite piece only with crazyglue. After the glue has dried and set - about 5 minutes - it is a snap to scrape and polish out the overspill on the surface cracks, leaving a repair that is visually pleasing and barely detectable at close range.
If you want to experiment with Gorilla Glue, try it on something else to discern if its properties are suitable for bakelite, please. I honestly don't know what Gorilla glue is for or what its composition is.
