Lines 1 – 2 |
2 | pharmaceuticals | The process is also used to preserve other sorts of material, such as pharmaceuticals. | Paragraph D;
Line 1 |
3 | manuscripts | Even valuable manuscripts that had been water damaged have been saved by using this process. | Paragraph D;

11 | composition | In addition, the composition and structure of the material is not significantly changed | Paragraph E;
Line 3 |
12 | overheating | The process continues for many hours (even days) while the material gradually dries out. This time is necessary to avoid overheating, which might affect the structure of the material. | Paragraph H;
