It is pretty hard for me to get this point, I mean I haven't took a lot of photos when I doing this, but I''ll keep doing it later. The course is funny, relaxing, I don;t really need to push myself out, or rush anything, it is all natural and smooth, even the hamming is tried though, but I got my muscle bump up lol. 

It is not good when I first time polish and curved this bowl, I mean, there still  amount of things needs to improve, even I already polished it, I wanted to make a better one than this. 

Polishing is nasty, not that good, because I didn't sanded enough.

When I finished first time, I was trying to make another one see if I can make it better than last one, but the problem is 1mm is too thin, it keeps crunch at the edge and I can't fix it, and every time when it bump up, it would split.

This is what I used for polishing, metal finish for first layer, silvo for reflection, and metal reflection for last layer.

I also tried this wax, it turns out same as what silvo did.

fiber for polishing.

Polish takes long time than I expected, first time I used 200 to 750 and finishing is bad, second time I start with 350, and then 600, 1000 and end with 1200, it feels nice, but still not reflecting as I thought. 

Hammer, really tired for working on this. 

failed second one and the female template.

split everywhere lol.

Template, I know I can't make a perfect circle, then I cut  a little bit to fit my bowl. 

Final polishing in vacuum machine. 

finished lol! 

I sanded the bottom, is 100% flat!!!!

Like I said, is not 100% perfect arc, but I like it, put a lot effort into it, polished three times, two times modification, guess I'm not that bad for first time learning punch metals lol.
