• Room temperature: 68–77°F (20–25°C).
• No drafts — turn off fans, close doors and windows.
• Burn on a stable, level, non-combustible surface (tile, glass, or metal).
• Trim wick to ¼ inch (6mm) before the first light.
• Observe and record flame height, melt pool diameter, and wick condition every hour.
• Extinguish after 4 hours (or your labeled burn time), let cool completely, trim wick, and repeat.

What to Record Per Burn Session

• Date, time, ambient temperature, and humidity.
• Wax type and lot number.
