“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.” [Emma] described Joseph “sitting with his face buried in his hat, with the stone in it, and dictating hour after hour with nothing between us.” Oliver Cowdery, testified under oath in 1831 that Joseph Smith “found with the plates, from which he translated his book, two transparent stones, resembling glass, set in silver bows. That by looking through these, he was able to read in English, the reformed Egyptian characters, which were engraved on the plates.”31 In the fall of 1830, Cowdery visited Union Village, Ohio, and spoke about the translation of the Book of Mormon. Soon thereafter, a village resident reported that the translation was accomplished by means of “two transparent stones in the form of spectacles thro which the translator looked on the engraving.” info https://www.churchofjesuschrist.org/study/manual/gospel-topics-essays/book-of-mormon-translation?lang=eng#org/topics/book
