The relationship between bone and ash weight to body weight and body length of Thai corpses in Bangkok and central part of Thailand after cremation

Abstract

Background: Although information about bone and ash weight compare to body weight and body length of Thai people exists, it was based on a few samples. Objective: Collect data of the bone and ash weight after cremation and find out the relationship between bone and ash weight, body weight, body length, and age. Material and Method: Two hundred and twenty three corpses, 97 females and 126 males were collected from four temples, three temples from Bangkok and one temple from Angtong province. The crematoria used in the present study created a temperature between 850°C and 1,200°C. Each cremation took about 1-1.5 hours. Results: The average with SD of bone and ash weight of males was 2.44 kg ± 0.9 Kg, while the weight of females was 2.07 ± 0.89 Kg, and the average of bone and ash weight of total subjects was 2.28 ± 0.95. There was negative correlation between age and bone & ash weight, while there was positive correlation between body length and body weight, body length and bone & ash weight, and body weight and bone & ash weight. The results of the present study indicated that age and body weight affected the bone and ash weight. The fitted linear equation was Log (bone & ash weight +1) = 0.413 - 0.001 (age) + 0.003 (body weight). Conclusion: Age and body weight affect bone and ash weight. Moreover, the age, body weight, and body length could be estimated by using the bone and ash weight.
