One singing bowl is in Brimstail's cave in the Tree Gnome Stronghold. The player can use the bowl to convert a small crystal seed into a crystal saw and it can also be used to revert a crystal saw or a crystal chime into a small crystal seed. This bowl becomes available during and after The Eyes of Glouphrie quest.
Another singing bowl is in Yewnock's cave in the Gnome Village Dungeon. The player can use this bowl to convert a small crystal seed into a crystal chime (not a saw) and it can also be used to revert a crystal saw or a crystal chime into a small crystal seed. This bowl becomes available during and after The Path of Glouphrie quest.
