A month ago we discussed water damage to Nahari ink. I then suggested drying the affected Sefer Torah in the sun, hoping that the ink will dry and be less susceptible to water damage. I made an experiment. The following was written with new-fresh Nahari ink on klaf. It was then allowed to air dry for two weeks. Then, the letter ד was wetted with water. Some ink spread on the klaf. The klaf was then baked dry at 100 degrees C for 2 hours, to make sure the ink is really really dry. The klaf was then taken out and allowed to stand in room air for 2 hours. Then, the letter ר was wetted with water. Some ink spread on the klaf, with a different spread pattern. It appears that drying the ink did not help. I now suspect that drying the Sefer Torah in the sun will also not help. Why does the ink spread even after good drying? .
