Soot and carbon caps signal too much fuel or turbulence. Trim the wick shorter, stabilize airflow, and limit sessions to three or four hours. If the jar blackens, cool completely, then wipe gently with a soft cloth and a touch of rubbing alcohol. Consistency prevents repeat buildup and keeps fragrance crisp. Watch the flame: a calm teardrop shape means your adjustments are working beautifully and safely.
If the wick slides off-center or struggles in pooled wax, recenter it while the wax is warm and pliable using tweezers and a steady hand. You can prop it with a wick holder as it cools. Absorb excess liquid wax with a cotton ball during a supervised burn. Chronic drowning often means the wick is undersized; compensate by trimming slightly shorter and shortening sessions to rebalance heat.
Soy frosting and glass wet spots are largely cosmetic, reflecting natural crystal behavior and cooling patterns. Warm the exterior briefly with your hands or a soft towel to improve appearance, but avoid aggressive heating that risks damage. Level wavy tops by allowing a full, patient melt on the next session. Embrace minor quirks as signs of real wax character, focusing on clean, safe, fragrant performance first.
