I have a reproduction porcelain sign I need to drill a hole through. I have a small die grinder bit for my dremel. Would this work for removing the porcelain and then drill through the metal back of the sign with a carbide drill bit? Also considering a drill bit suitable for glass. Any suggestions?

I've had good luck with using a glass cutting bit, just take it slow and easy.

I once did the same thing with a repro sign. I just placed a piece of tape over the spot, and used my cordless drill and a titanium bit on the lowest speed to get through the porcelain. Worked like a charm.

Masking tape and a regular drill bit worked fine for me.

Heat does not seem to be an issue, in fact I have used heat to soften and repair some chips. The important thing is to support the sign so it does not bend during drilling. Any deflection of the metal will chip off chunks. The last drilling I did was one of my homemade address numbers that I forgot to punch before enameling. Using a plain HSS bit and drilling on a steel plate the hole appeared clean with light chips around the edges.
Antique? It's new to me.
