You seem to be confusing glass-encased vigil candles with free standing candles.
1) Do not pour wax out of a vigil candle. It should naturally consume all the way down to the bottom and all the wax (or most of it) will be consumed).
2) The concept of "saved" wax comes from burning free standing candles that leave behind a puddle of melted and re-hardened wax.
3) Folks who burn free-standing candles bury the wax in the back yard where they live -- BUT you ain't burying any wax, because you are burning a VIGIL candle.
I recommend that before you make a lot of mistakes, trying to read about this stuff on the internet, you buy a copy of my simple, basic book, "The Art of Hoodoo Candle Magic. It explains every type of candle and how we work with them.
Good luck!
