“…Phoshorus absorption of fish bones meals is similar to that of fish meal and animal bone meal in pigs (Rodehutscord et al, 1997). From the Far East, where calcium deficiency is prevalent, there are some reports on fish bone (Deng, 2001) and tuna bone preparations intended as food supplements (Kim et al, 2000a,b). Homogenized fish bone has also been proposed as a weaning food mineral supplement (Martínez et al, 1998).…”

In general, there is a lack of scientific documentation of nutritional value of marine by-products. The bone fraction from fish has been regarded as waste. Due to the high mineral content of fish bones, this material can be well suitable as a natural calcium source. In the present study, apparent calcium absorption of different fish bone sources was tested using growing pigs. The experimental diets consisted of boiled salmon frames, or salmon, saithe or cod bones treated with enzymes. Calcium carbonate (CaCO(3)) was used as control. The experimental diets were formulated to contain 0.7% total calcium of which the added calcium source to be tested contributed about 71% (study 1) and 86% (study 2). Except for the calcium and phosphorus sources, the animals received similar basal diets. Apparent calcium digestibility coefficient was calculated using yttrium as indicator (both studies) and was based on complete collection of faeces and urine (study 2). The experimental design was parallel and cross-over in study 1 and study 2, respectively. In study 1, piglets getting salmon bone treated with enzymes had significantly higher calcium absorption than piglets getting boiled fish bone or calcium carbonate. Therefore, in the second study only enzymatically treated fish bones were included. The higher calcium absorption from enzymatically treated salmon bone was also found in study 2, but this time not significant. Calcium from boiled salmon bones in study I, and from enzymatically treated saithe and cod bones in study II were absorbed as well as the calcium carbonate control. The results indicate that fish bones may be a useful and well absorbed calcium source. Due to the high mineral content of the bone fraction, salmon bones can be well suitable as a natural calcium and phosphorus source in, for example, food, feed or as supplement.

“…Many approaches have been developed to precisely analyze the firing temperature of ancient Chinese ceramics. Mossbauer spectrometry [8][9][10][11] was performed to investigate the state and coordination of iron ions in Fe-base glazes and indicated that the firing temperature of tricolored glazed pottery (Tang Dynasty, Yaozhou kilns) is around 1,000 C. Lee et al and Liu have measured the phase transition and crystal decomposition temperature of raw materials using differential thermal analysis and concluded that the optimal firing temperature of high silicon tailing billets was 1,120-1,150 C. [12,13] Li et al have applied thermal expansion technology to detect the expansion and contraction of porcelains during the reheating process and demonstrated that the firing temperature of Jun porcelain of Liujiamen sites (Song Dynasty, Henan province) was between 1,161 C and 1,307 C, with an error less than 66 C. [14] Besides, this method was performed to measure the firing temperature of Di ware fragments from Wayaoyang sites (Southern Song Dynasty, Zhejiang Province) at approximately 1,270 C. [15] Thermal expansion technology, as a common method of measuring temperature, is also used for pottery and colored glazes. [16] However, those methods required rigorous sample preparation and were destructive for ancient ceramics.…”

Firing temperature is an essential indicator for the level of the manufacturing technology of ancient ceramics. Current techniques for measuring the firing temperature of ceramics are generally destructive and very complex. In this work, a series of celadon fragments were prepared at different firing temperatures (from 900 to 1,300 C) and studied by Raman spectroscopy, X-ray fluorescence (XRF), and X-ray diffraction (XRD). The XRD results show that raw materials were dissolved and melted completely to form the glass matrix of a glaze above 1,100 C. Besides, the results of XRF and Raman tests demonstrate that CaO amounts in the glaze decrease significantly with the increase in firing temperatures, which is the main factor to influence the Si-O linkages, adjust Q 1 , Q 2 , and Q 3-4 components, and modify the structure of the glass matrix during the firing process. The area ratios of the Si-O bending over stretching envelopes (A 500 /A 1,000 ) of the glassy matrix have a negative correlation to the CaO amount. In contrast, the value has an apparent positive correlation to the firing temperature. The A 500 /A 1,000 value of the glass matrix increases from 1.29 to 2.40 as the firing temperature increases from 1,100 C to 1,300 C. These results prove that Raman spectroscopy could be used as a feasible and reliable nondestructive method to establish a more accurate relationship between Raman spectral polymerization index and the firing temperature in order to identify the firing temperature of ancient ceramics.
