When I saw the lost wax casting page, all I was thinking was, that design is way too simple for that method of creation... Lost wax casting is used for really complicated and intricate designs. That kind of ring can be made in less than an hour if you fabricate it with round or half-round rod... Also, why would you use a rasp? That's way to slow? Try a flex-shaft! Seriously!
If you are a student, which he is, and you are just learning about wax casting, then you'd do exactly that. He's studying jewelry making, he's not a professional.
Just looked on Lezhin, this chapter was the season two finale and it updated yesterday... apparently it only updates 3 times a month, so I will check back on October 9th and see if the next season has started yet.
This chapter originally released a few weeks ago. I heard from someone who can read Korean that it wasn't returning until November. :/
NooOOooo0ooOOoo ;_;
