direction and South-Eastern direction as the result that this research was calculated volume by classifying interpretation 
category into 4 directions through rotating by 90 from the center of the temple bell. This is because the section 
thickness of new bell was cast relatively thickly in the direction of North-East and South-West in comparison with the 
direction of North-West and South-East. 
This research could calculate the specific gravity of alloy from the weight of 18.9t and the volume of the temple bell 
which was calculated at July in 1997.

3.2 ANALYSIS OF SECTION 
This research was performed the analysis of section about diverse patterns and that of section about 4 directions 
(South-Northern, East-Western, South-Eastern and North-Western, South -Western and North-Eastern) by using 3 
dimensional model about the bell. Figure 4 about the bell is the result of section analysis about dangjwa out of the 
patterns of the bell, and figure 5 is the result that this research was analyzed the thickness of section of the direction of 
South and North at the interval of 20 Ytoward upper direction. 
Dangjwa in figure 4 is the result that this research was analyzed section at the interval of 10 Y respectively toward 
horizontal direction and vertical direction as the dangjwa located at Southern side. Then, we can see that the section of 
horizontal direction(3-3' section) and vertical direction(8-8' section) is symmetry generally. Figure 5 is the result that 
this research was analyzed the section of direction of South and North. Then, this research could know that the 
thickness of section located at the upper direction of 2.5m or so, from total lower end is thickest and that the upper 
direction section of 1.25m or so where dangjwa was located was cast most thickly. It is maintaining the uniform section 
thickness of 0.1m - 0.15m or so on the whole. We may presume that the section of left and right is forming symmetry 
form on the basis of central line and that it was cast by precise casting frame.

3.3 ANALYSIS OF PATTERN 
As the result that this research was tried to compare the geometrical location relation between the centers of two 
dangjwas being cast in the direction of South and North of the surface of the bell, the deviation of horizontal direction 
between dangjwa centers is 0.8 Y or so, and the deviation of vertical direction is 0.5 Y or so. Thus, if we consider 
measurement error, we can see that they are being cast at very exact position. As the result that this research was tried 
to overlap the beechonsang(NW-SE, NE-SW) of similar form, it showed that form or size was similar but that cast 
position is more or less different partially. With this, it can be interpreted that many casting frames were used by 
compounding them so as to form beechonsang.
