The suitable refinning degree of Japanese black charcoals has been studied by writers.As the experimental materials, we used the black oak charcoal and we cut them 8〜9 cm and tested by the refinning meter, and divided 5 groups by refinning degree, 1〜2,3〜4,5〜6,7〜8,9.Each group was accepted a combustion test and studied the relationship between refinning degree and combustion state.We have found that the suitable refinning degree was 6〜7,judging from heat efficiency and combustion time.
