thông phong
Definition
- Noun:
- Glass lamp chimney: A cylindrical or funnel-shaped glass tube placed over the flame of an oil lamp. Its primary functions are to protect the flame from drafts (wind), to provide a steady upward airflow ("thông phong" literally suggests "ventilating" or "allowing wind to pass through"), and to increase the lamp's brightness and efficiency by concentrating the heat and light.
Usage Examples
- Noun:
- Bà tôi cẩn thận lau sạch cái thông phong trước khi thắp đèn dầu. (My grandmother carefully wiped the glass lamp chimney clean before lighting the oil lamp.)
- Ngọn lửa cháy đều và sáng hơn nhờ có thông phong. (The flame burned steadily and brighter thanks to the chimney.)
- Tiếng thông phong nứt vỡ làm cả nhà giật mình. (The sound of the lamp chimney cracking startled the whole house.)
Advanced Usage

It is a specific, technical term for a historical household object and is not commonly used in modern daily language except when referring to traditional or antique oil lamps.
