Wick problems I purchased 2 candles in bowl like glas jars and the wicks on both are under the wax. what do I do to fix it or how do I get the candles out to re use the glass?

Turn the bowl upside down and use a match or much better, a cigarette lighter to melt the wax directly below (normally above) the black wick, moving the flame it back and forward. Watch out for hot wax dripping onto your skin!
Then turn the bown over and use a butter knife to scrape the wax above the wick away and remove the wax above and on either side of the wick. You may have to do this operation a few times, but eventually you should be able to gently get the knife under the buried wick and (gently!) prise it back into an upright position.
Don't do this roughly, or you could snap the wick off at its base, it needs to be pretty much out of the wax and softened by the flame before you try to bend it back up.

Then light the cantle and let it burn for ten minutes, until the wax all around it is clear liquid - then blow it out, and after ensuring that the wick tip is no longer glowing, quickly crush a few absorbent paper towels into the bowl and upturn it again. The aim is to allow the towel to absorb excess molten wax, which should preven the wick from being buried under wax again when the candle cools.
