Other Characteristics
When todorokite was first discovered, in 1934, modern methods of mineral analysis were not available, and one of the standard techniques was to use a blowpipe to heat a small sample of the mineral, and observe its behavior. Todorokite was tested in this way, and it was noted that under the blowpipe it turned brown and lost its metallic luster, but did not fuse.
X-ray diffraction lines at 9.5 to 9.8 Å and 4.8 to 4.9 Å are characteristic. This is also true of buserite Na4Mn14O27·21H2O.
