When making container candles, I've found pouring your glass containers at 150 degrees will give you the most adhesion. Its also useful to heat your jars with a hair dryer or heat gun for 15 seconds before you pour. You don't want to get the jar hot, but warm to the touch so you don't have cold shock.
Also, pouring at 150 will guarantee a smooth flat surface without sink holes or cracks, which can be caused by pouring too hot (165 and above for containers).
Keep in mind glass and wax adhere and seperate at different tempatures, so even if you've made a candle with full adhesion it still can blotch and seperate from the glass if left in a cold place, or in high heat.
We've recently learned that when using the accu waxes, pouring hotter is some times recommened. With the as-10 and the ap-30 the pouring temps can range from 145-180 I've notived with large containers, like our candy jars which are 4" in diam & about 4-5" tall, needs to be poured hotter, around 175-180. While my smaller jars, like our 6oz tins and 4oz jars which are 3" diams & 2-3" tall can be poured anywhere between 140-175.
