They believed that by subjecting lead to a series of chemical and alchemical processes, they could eventually transform it into gold. However, this was never achieved.

In modern chemistry, it is possible to change lead into gold, but only by using a particle accelerator. This process is very expensive and not practical for commercial purposes.

The crossword clue "Metal that an alchemist “converts” into gold" could also refer to the philosopher's stone. The philosopher's stone was a legendary substance that was believed to be able to transmute base metals into gold. However, the philosopher's stone was never found.
