What I Learned from Using Deg-Bhapka for 30 Days | #DegBhapka #SteamDistillation
The Deg–Bhapka system of Kannauj is a traditional steam distillation apparatus used for extracting attar (natural perfume) for over 1,000 years.
Long before modern chemistry labs, Indian perfumers mastered phase change, condensation, and volatile oil extraction.

🔬 The Science Behind Deg–Bhapka Steam Distillation:

✔ Deg = sealed copper vessel holding flowers + water
✔ Heated gently → water turns into steam
✔ Steam carries volatile aromatic oils
✔ Vapors pass through bamboo pipe (chonga)
✔ Vapors enter Bhapka (receiver vessel)
✔ Cooling causes condensation
✔ Oil dissolves into sandalwood oil base

👉 This is true steam distillation, identical in principle to modern lab stills.

🧪 Why copper & clay are critical:

✔ Copper ensures even heat distribution
✔ Prevents overheating & oil degradation
✔ Clay sealing creates airtight pressure control
✔ Low-pressure system preserves delicate aromas

🌡 Thermodynamics at work:

✔ Controlled boiling point
✔ Latent heat of vaporization
✔ Selective volatility (only aroma compounds travel)
✔ Natural condensation without chillers

🌸 Why Kannauj perfected this:

✔ Rich flower belt (rose, kewda, jasmine)
✔ Access to sandalwood oil (natural solvent)
✔ Generational knowledge transfer
✔ No synthetic chemicals used

🧠 Why modern labs still respect it:

✔ Zero synthetic contamination
✔ Superior aroma complexity
✔ Slow extraction = stable molecules
✔ Eco-friendly & biodegradable process

Modern perfume industries still use steam distillation — proving that Kannauj’s Deg–Bhapka was chemical engineering centuries ahead of its time.
