Si Collection, Middle Volume. Radical: Fire (huǒ). Character: 炌. Kangxi stroke count: 8. Page 667, Entry 11.
According to Collected Rhymes (Jiyun) and Classified Anthology (Leipian), pronounced jie (falling tone). According to Jade Chapters (Yupian), it means bright fire. According to Collected Rhymes, it is the same as the character pronounced kai (falling tone). Note: Jade Chapters contains 炌 but not the character pronounced kai, while Broad Rhymes (Guangyun) contains the character pronounced kai but not 炌. This is likely because the two are variant forms, and each dictionary recorded only one. Jade Chapters lists them separately, but since 炌 is identical to the character pronounced kai, and Broad Rhymes states it is the same as the character pronounced kai, it is clear that these three characters represent a single word. See the entries for the two variant forms for further details.
