Chip Thompson from Solid Rock Cafe uses the illustration of the translation of the Book of Mormon plates for some fascinating discussions.
The quote given by Thompson can be found on the lds.org website and reads:
Nevertheless, the scribes and others who observed the translation left numerous accounts that give insight into the process. Some accounts indicate that Joseph studied the characters on the plates. Most of the accounts speak of Joseph’s use of the Urim and Thummim (either the interpreters or the seer stone), and many accounts refer to his use of a single stone. According to these accounts, Joseph placed either the interpreters or the seer stone in a hat, pressed his face into the hat to block out extraneous light, and read aloud the English words that appeared on the instrument. The process as described brings to mind a passage from the Book of Mormon that speaks of God preparing “a stone, which shall shine forth in darkness unto light.”
