阴沉木是什么木头
阴沉木,又称古沉木、乌龙木、乌木、沉木、炭化木、东方神木等,系古时沉于水土之中的木材。远古时期,原始森林中的大片名贵木材,受地震、山洪、泥石流等重大自然灾害侵袭,成为被深埋于江河、湖泊、海底的枯木残根。
它是三千年至万年前,古四川地域天体发生自然变异,由地震、洪水、泥石流将地上植物生物等全部埋入古河床等低洼处。一些埋入淤泥中的部分树木,在缺氧、高压状态下,细菌等微生物的作用下,经过数千年甚至上万年的炭化过程而形成,故又称“炭化木”。
有老师说是阴沉木?
阴沉木又叫乌木,是楠木、红椿、麻柳等树木因自然灾害埋入淤泥中,在缺氧、高压状态下,细菌等微生物的作用下,经过长达成千上万年的碳化过程而形成的,所以又称为“炭化木”。
阴沉木鉴定
1、阴沉木的本质是碳化木,它介于炭和木之间,有着自己独特的木质性质;而是否属于阴沉,一般看碳化的程度,碳化得太厉害反而成煤炭了。
2、一般完全进入阴沉级别的树木,起码需经历上千年时间的浸润。它的树身多为全身乌黑,呈现碳化状。
3、阴沉木比较奇特,一般木头(水沉木也是,特例除外)烧出的是白灰,而阴沉木烧出的是黄灰。
4、阴沉木遇水颜色加深,水干后恢复本色;涂上小许菜油则乌黑锃亮,不褪色。
什么是阴沉木?
阴沉木是由于地壳变迁如地震、洪水、泥石流等自然灾害因素使得古森林倒埋于古河床低洼深处或者淤泥里在缺氧、高压以及弱酸、微生物共同作用的环境下,历经成千上万年缓慢炭化而形成的一种特殊木料。
阴沉木的颜色光鲜,细腻光滑,致密耐腐,具有特殊香味,较同种现代木相比,阴沉木内含物(如树胶、精油)含量较多,密度较大,尺寸稳定性较好,耐腐性能较强。在阔叶树中以壳斗科、樟科和木兰科阴沉木树种较为常见,针叶树以柏科、杉科阴沉木树种较为常见。
扩展资料:
阴沉木自古以来就被视为名贵木材,稀有之物,是尊贵及地位的象征。我国民间素有“纵有珠宝一箱,不如乌木一方”和“黄金万两送地府,换来乌木祭天灵”的民谚。在古代,达官显贵、文人雅士皆把阴沉木家具及出自阴沉木雕刻的艺术品视为传家、镇宅之宝,辟邪之物。
阴沉木是对人体有益的,特别是对脾气暴的人,可以安神定气.不要听着阴沉木三个字就觉得吓人。阴沉木是被清代皇室列为御用木材的,民间不能擅自使用,常用作宫殿栋梁,或制成小物件佩戴把玩,古时官宦人家和文人雅士常把阴沉木制成的家具作为传家之宝。因为埋藏地下百年甚至千年,能量大于水晶。
