Speak to Juna to unlock the ability to make the bowl. If you have completed The Chosen Commander since your last visit to the Tears, you will have to go through some dialogue before Juna will inform you of how to craft the bowl. Use a sapphire lantern on one of the light creatures to pass across the chasm and mine one of the magic stone rocks. Craft the larger rock into an ornate stone bowl. After making the bowl, go east and jump across the gap, then go north to speak to Juna. She will keep the bowl for you to use to collect the tears.
