It was not until 1897 that they settled on cotton thread that had been carbonized as the best they could do. |
In six weeks, they excavated the remains of a home, which had been carbonized from the extreme heat of the volcanic eruption. |
Once cooled, the outer clay is chipped away and the carbonized core reamed out, with the casting filed and chased. |
When one of these sedimentary rocks is split open a carbonized fossil is sometimes exposed at the rook face.

Then, certain classes of materials, including wood charcoal and carbonized seeds, were re-examined and identified. |
Good examples of carbonized fossil plants are found in the roof shales of coal mines. |
