Jar-candle making question. (great)

[ESFP]

How do you make a jar candle to keep it from shrinking in the middle? When ours dries, they shrink in the deep end and need refilled. There must be a way, as store-bought candles are full and level at at the top. Any suggestions would be greatly welcome. Thanks.

Look for wax specifically made for container candles. Try not to overheat your wax. The hotter you get it, the more it will shrink.
Most people pour twice for container candles anyway. Don't fill full the first pour. Then the second pour finishes it.

I heat the jar in the water and let the water and wax cool before I remove jar.

That makes sense! Thanks so much. I'll be looking forward to using these suggestions.
