How to get putty off of porcelain figurine

If you make your hole too large (too allow for shrinkage and 'play' to get it perpendicular to the pull/plumb), then as you glue the nut inside, you need some sort of method for hold the nut in place while the glue dries, otherwise it will shift out of plumb as it hardens, which looks mighty sad when stuck onto a cabinet at an angle. What I found that the method of gluing any type of fastener into the clay piece led to less than desirable results. I chose this because I wanted the barbs to help hold the glued nut into place. I used to glue in a threaded nut which was made to be pressed into manufactured wood materials (MDF etc) the 'nut' had barbed projections, and was about 3/8' long. I make a couple hundred door pulls/knobs per year. Let us know how this turns out so we all can learn from your experiment. If you reglazeВ a commercial piece the only way to find out what will happen is do it and see.Testing its whats need -either way you will learn a lot from doing it.You do not know what temperature the commercial stuff is fired to so that also will be learning curve-what if its low fire or high fire and you are doing cone 6?Only way is to try it.

I have made sinks for specific hardware as well-same deal need to know the shrinkage rates.I made big game =ceramic headed fishing lures with a specific hole size. Just make it big enough to fit when shrunk after firing.I have made ceramic faucet handles that fit over brass fixtures and had to figure the hole sizes and firing with about 99% area glazed-its all a learning curve If you need a side hole for the screw you can make that as well. The tough thing is figuring the shrinkage -its best to have the space be larger and fill with epoxy like JB weld(if you live in the US?). Make the knob and leave room to epoxy the spindle/nut into.
