why scribe the lines on the inside once completed? - they seem to serve no purpose other than decoration.

Those Bombay safety boots get me every time!!

Measurement lines for liquid maybe? Save time with measuring cups when making large meals is what I was thinking. Or rice...anything.

Maybe the lines are so you can tell the depth by feel, because after not many years of arc welding with a pair of sunglasses and grinding with nothing on, your eyesight's gonna be pretty bad.

Nothing wrong with his eyes or the steadiness of his hand. We should be admiring his skill, nice even edged cuts with the gas, nice welds considering his welder is probably primitive and his electrodes very low quality. He is also proud of his work. Don’t worry about his lack of safety boots, eye protection, gloves, respirator, hard hat etc, he lives in a country where he has the freedom of choice. Unlike the western world where health and safety is often more about how much they can fine companies for not complying. Those fines then go into paying the wages of those that write the rules.
The scribed lines are common on cooking utensils from the Indian subcontinent. Even flat items such as Tawa/Tavares have them, and they don’t hold liquid, so I would assume they are just for decoration.

I thought that originally, but then they're so high up towards the end I thought unless you're feeding 50ppl at a time, the meals would be massive.
