If the glass top is already broken, you can use a torch and heat the pieces that are glued to the metallic parts you want to recover. The best way to do it without special tools is to reduce the size of the glass portions around the metal parts (use an old cloth to cover the glass and a hammer to hit and shatter the glass - USE PROTECTION) and then place the metallic parts with whatever is left of the glass glued to them in the oven and heat them up to 150 C or 300 F and they should come apart (you may need to reach higher temperatures, depending on the adhesive that was used to glue the metal to the glass).

Good luck!
