The result of second casting is much better than first one. Left is the second and right is first. The surface condition of second one is much better than first. However the edges of high part of second cast is dull. The temperature of second cast might be lower than first. I feel the temperature was too high in first case.
結果は一回目よりはるかにいいです。左二回目、右一回目、表面の艶が全く違います。ただし二回目のは鋳型の上部に湯が良くまわっていないので、温度が低かったと思われます。一回目は温度が高すぎたのかもしれません。
