玻璃石，又音译作托立尼提物质（英语：Trinitite）是一种玻璃状人工矿物，最初在1945年7月16日美国新墨西哥州奥特罗县县治阿拉莫戈多（Alamogordo）进行的以钚元素为基础的三位一体核试爆炸后在沙漠造成了一个深10英尺（3.0米）及宽1,100英尺（340米）的辐射玻璃结晶小山发现，那是因为高温把沙的硅质晶体熔化后再凝固形成的玻璃状再结晶物质。这种玻璃状再结晶物质主要由长石砂形成，即一种含石英晶粒及丰富的长石晶粒（包括有钾长石及少量斜长石，还有少数由方解石、普通角闪石与普通辉石混合而成的沙质黏土），在原子弹爆发后融溶。颜色一般是浅绿色，再加上一点深浅变化，若有其他颜色则是掺入有其他金属，如：铜（红色）或铁（黑色）。辐射量轻微，但可安全处理。

Trinitite, also known as atomsite or Alamogordo glass, is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico. The glass is primarily composed of arkosic sand composed of quartz grains and feldspar (both microcline and smaller amount of plagioclase with small amount of calcite, hornblende and augite in a matrix of sandy clay) that was melted by the atomic blast. It is usually a light green, although color can vary. It is mildly radioactive but safe to handle.
