I know you have to use an Ornate Pitcher, but are you supposed to throw the empty pitcher into the bonfire, or does it have to be filled with a glade potion before you toss it in? I would not like to do something wrong and lose my 'spensive pitcher...Thank you in advance for answering.

i threw the glade potion in the bonfire and got a harvest potion

You have to turn the pitcher into a glade potion by visiting Peka Glade at either 8am or 8pm Subeta time, and then throw the glade potion into the bonfire for a harvest potion.

Thank you both very very much. You kept me from making a costly mistake. I was going t toss the empty pitcher in the fire.

It doesn't appear when you go to the Bonfire anyways (in the area where you see the items that can be burned), so no worries

No problem! I'm fairly new here so I was figuring all this out as well ^^ With my first Fireside and the new harvest pets, it was quite confusing lol
