Wick test in 6006 in 8oz square mason jar with eco 10 wick.

After 2 hours wick is mushrooming . Did I over wick ?

The photos appear that your current wick choice is on the too big side. The flame looks very robust for the top of the jar.  That jar will build heat steadily through the entire burn.  The proportionally smaller opening and long-ish neck usually needs a wick down compared to jars that are straight from top to bottom. 
 

I would drop down at least several sizes. 
 

I suggest an IR thermometer to periodically check the glass temp as the candle burns.  Aim it at various sides of the jar, especially toward the side of the jar the flame points to and make sure the glass temp does not exceed 175*F at any point. 175 is the ASTM limit for container temp for candles to be considered “safe”.

Yep, you are several sizes too large for a mason jar.  The wick guide at candlescience. com is accurate for 6006.  Additionally, they offer wick suggestions for 6006 and other waxes on the product page for each container they sell.

Eco 4 is what is suggested for mason jars and they do work very well.

It all depends on your particular wax box, fragrance and container.

 

you can certainly try that size, then adjust down accordingly as needed.  The shape of the jar will change later burns, making them hotter the deeper into the jar you go.
 

to know for sure, you’ll need to burn the entire candle. Then make another once you have chosen your wick and burn it to the end without perfectly trimming your wick each time. As much as we expect others to be perfect candle burners, we all know they are not.

Every case of wax has a manufacturing lot number on it.  Lots of wax vary from batch to batch. Some vary so little as to be insignificant. Others may be off by several wick sizes,  many of us learned this lesson the hard way.
