| None of these features was seen on our unoxidized Belgian specimens. |
| This was partially due to a lack of technology to concentrate the deeper unoxidized ores and the high cost of transportation to the nearest railhead. |
| The unoxidized minute traces of sugar signified imperfect combustion. |
| It is only the unoxidized pale greenish stuff that can act as the dye, the dark brown itself has no affinity for the wool. |
