I didn't managed to snap the photo of the teapot before it is being polished. The shop says that picture 1 is how the colour and texture looks like (it is a different pot).

Process of polishing, is to use sandpaper roughness 500, 1000, 1500, 2000.
Each sandpaper is divided into 4 pieces and each piece for 30 minutes. Use water to wet and rinse the teapot in between. Total hours to spend, 16.



This is the result of 4 hours work. WIll try to show the result when it is ready.
PS: The teashop got influenced by another forumer here who has successfully polished his pot so beautifully
