Ball candles are molded spheres that work as sculptural decor first and light source second, which changes how you should judge them.
- Diameter, because a three-inch sphere reads as a small accent and a six-inch one anchors a whole table.
- Wax type, since soy and coconut blends burn cooler and slower while paraffin holds crisp molded detail.
- Burn behavior, as a sphere collapses unevenly without a flat base or a holder that catches melted wax.
Decide whether you want to light them or keep them unlit as decor, then pick the size and holder to match.
