\/>\n At around 1,650 \u00b0F (900 \u00b0C), the heat and water from the clay promote the formation of a wustite (FeO) layer, which is a type of iron oxide formed in the absence of oxygen. In this reducing environment, the silicon in the clay reacts with wustite to form fayalite (Fe2SiO4) and, at around 2,190 \u00b0F (1,200 \u00b0C), the fayalite becomes a liquid. This liquid acts as a flux, attracting impurities, and pulls out the impurities as it is squeezed from between the layers. This leaves a very pure surface which, in turn, helps facilitate the forge-welding process<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u65e5\u672c\u5200\u306e\u6a21\u69d8\u306f\u300c\u713c\u5203\u571f\u300d\u3092\u5857\u308b\u300c\u571f\u7f6e\u304d\u300d\u306b\u3088\u3063\u3066\u4eba\u70ba\u7684\u306b\u4f5c\u3063\u3066\u3044\u308b\u3053\u3068\u3092\u4eca\u56de\u521d\u3081\u3066\u77e5\u308a\u307e\u3057\u305f\u3002 \u7c98\u571f\u3001\u7825\u77f3\u306e\u7c89\u3001\u58a8\u306e\u7c89\u3092\u6df7\u305c\u305f\u3082\u306e\u3092\u539a\u3055\u3092\u5909\u3048\u3066\u5857\u308b\u3001\u8abf\u5408\u3084\u6210\u5206\u306b\u79d8\u4f1d\u304c\u3042\u308b\u3001 \u4e7e\u71e5\u5f8c\u3001\u52a0\u71b1\u2192\u6025\u51b7\u3067\u713c\u304d\u5165\u308c\u3002 \u5857\u304c\u8584\u3044\u90e8\u5206\u306b\u306f\u713c\u304c\u5165\u308a\u3001\u539a\u3044\u90e8\u5206\u306b\u306f\u713c\u304c\u5165\u3089\u306a\u3044\uff08\u6210\u5206\u306b\u3088\u3063\u3066\u306f\u9006\u3082\u3042\u308a\u3046\u308b\uff09\u3002 \u8a73\u3057\u3044\u89e3\u8aac\u306f\u4e0b\u8a183\u3064\u76ee\u306e\u3088\u3046\u306b\u8ad6\u6587\u306b\u306a\u3063\u3066\u3044\u307e\u3059\u3002 \u713c\u304d\u5165\u308c\u3067\u6c34\u306b\u5165\u308c\u305f\u3068\u304d\u3001\u6c34\u84b8\u6c17\u304c\u767a\u751f\u3059\u308b\u3068\u51b7\u5374\u901f\u5ea6\u304c\u9045\u304f\u306a\u308b\u3002\u8584\u304f\u5857\u3063\u305f\u3068\u3053\u308d\u306f\u5c11\u3057\u65ad\u71b1\u3057\u3066\u6c34\u84b8\u6c17\u767a\u751f\u3092\u6291\u3048\u3064\u3064\u3001\u7c98\u571f\u306e\u9699\u9593\u306e\u6bdb\u7ba1\u73fe\u8c61\u3067\u6c34\u304c\u5c11\u3057\u305a\u3064\u4fb5\u5165\u3057\u3066\u51b7\u5374\u901f\u5ea6\u304c\u901f\u3044\u3001\u306a\u3069\u8907\u96d1\u3067\u3059\u3002\u773c\u3068\u6700\u7d42\u6027\u80fd\u691c\u67fb\u3060\u3051\u3067\u3001\u3088\u304f\u305d\u3093\u306a\u65b9\u6cd5\u3092\u958b\u767a\u3067\u304d\u305f\u3082\u306e\u3060\u3068\u601d\u3044\u307e\u3059\u3002&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[42,44],"tags":[5,7],"class_list":["post-1208","post","type-post","status-publish","format-standard","hentry","category-tech","category-materials","tag-tech","tag-materials"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=\/wp\/v2\/posts\/1208","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1208"}],"version-history":[{"count":0,"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=\/wp\/v2\/posts\/1208\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1208"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1208"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sekaiken.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1208"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
