The salt spring exploitation from Hălăbutoaia - Ţolici (Neamț County, Romania) dates back to the Early Neolithic and lasted throughout Chalcolithic. The deposit stratigraphy is estimated at 8 m and covers 2500 years of history (c. 6000–3500 BCE). In order to document the possible use of plants, particularly of the grasses, in the salt production process, we realized a detailed study of phytoliths preserved in several archaeological levels of Hălăbutoaia site. The most identified morphotypes come from grass family. Analysis revealed an important representation of inflorescence bracts phytoliths (especially Elongate dendritic) showing the anthropogenic origin of the assemblages. Bilobate are also well represented. These forms attest the presence of wild panicoid grasses (e.g. wild millet) and/or cultivated millets in the area. In some very punctual assemblages, forms produced by dicots are well represented. Considering the low phytoliths production by dicots plants, it involves a special accumulation of these types of plants that could be related to woody plants used as fuel for salt production. It is very possible that grasses had a very important role in pyrotechnology used to produce salt, either as the main fuel or as a mean for controlling the temperature or even as a firelighter.

来自Hălăbutoaia -Ţolici（罗马尼亚Neamț县）的盐泉开采可以追溯到新石器时代早期，并持续遍及整个石器时代。矿床地层估计为8 m，覆盖2500年的历史（约公元前6000-3500年）。为了记录植物在制盐过程中可能使用的植物，尤其是草的用途，我们实现了对Hălăbutoaia遗址几个考古级别保存的植物石料的详细研究。最确定的形态型来自草科。分析揭示了花序片植硅体（尤其是E longate树突状）的重要代表，显示了该组合的人为起源。乙ilobate也有很好的代表。这些形式证明了该地区存在野生的圆锥形草（例如野生粟）和/或栽培的粟。在一些非常准时的组合中，很好地体现了双子叶植物产生的形式。考虑到双子叶植物的植硅体产量较低，这涉及这些类型植物的特殊积累，这可能与用作盐生产燃料的木本植物有关。草很可能在用来产生盐的热解技术中起着非常重要的作用，它既可以作为主要燃料，也可以作为控制温度的手段，甚至可以用作打火机。
