Investigation of Wide Regional Interchange from the Jomon to Kofun Peiods Utilizing Tubular red oxide of iron

在古代日本，从绳文到古坟时代，红色颜料通常被认为是指汞朱砂和红色氧化铁（“bengara“）。这些红色颜料被涂在陶器和木制品等上。在挖掘调查中，有时会发现小心地储存在容器中的孟加拉豆。现在，我在孟加拉豆色素中发现了管状颗粒。这些颗粒就是孟加拉豆本身。从红色颜料“Bengara”中，我们可以得到许多有价值的信息，例如广泛的区域交流。我确信从绳文到古坟时期，日本列岛各地都有管状的bengara。目前还没有发现管状bengara的生产地区，我将尝试搜索在哪里获得。

In ancient Japan, from the Jomon to Kofun periods, red pigments are generally thought to refer to mercury cinnabar and red oxide of iron ( "bengara " ).These red pigments are painted onto earthenware, wooden objects, and others. Bengara carefully stored in vessels are sometimes found in excavation surveys.Now, I have found pipe-shaped particles in bengara pigments. These particles are bengara itself. Pipe-shaped bengara are very typical substances, therefore we can try to get a lot of valuable information, such as wide regional interchange, from red pigments "Bengara".I am certain that pipe-shaped bengara had been moved around the Japanese Islands from the Jomon to Kofun periods.Producing districts of pipe-shaped bengara have not been found, I am going to try to search where that obtain.
