Claim 0:
1. A method of manufacturing a single crystal using a crucible for growing the single crystal,
wherein the crucible accommodates a raw material melt for growing the single crystal being solidified therein and comprises:
a side wall part configured to surround the raw material melt; and
a bottom part configured to support the raw material melt while being continuous with the side wall part,
wherein, in a horizontal cross-sectional view, the side wall part is of a smooth, closed, curved shape, has a thickness of 1 mm or less, includes an outer surface having a recess and able to contact a crucible outer circumference holding jig, and is able to extend outward at a position of the recess when removing the crucible outer circumference holding jig from the recess, and
wherein the method comprises:
melting the raw material in the crucible;
abutting the crucible outer circumference holding jig with the recess when the raw material is in a melting state;
removing the outer circumference holding jig from the recess after complete solidification of the raw material melt inside the crucible; and
cooling the crucible after removing the outer circumference holding jig from the recess.
