There is a good amount of history about the "goings and comings" of the Alchemist's Glass Vial and the Confectioner's Glass Bottle. Both the Glass Vial and the Glass Bottle are made from Glass Nodules.
Some years ago the Formula for the Glass Vial was changed to increase the yield of Glass Vials from Glass Nodules (Ths ratio is currently 2 Glass Nodules per batch of 5 Glass Vials at optimum Earthencraft Skill). No corresponding change was made to the Formula for Glass Bottles (currently 4 Glass Nodules per batch of 2 Glass Bottles at optimum Earthencraft Skill).
Please change the Glass Bottle Formula to require 2 Glass Nodules per batch of 5 Glass Bottles, to bring it into line with the Glass Vial Formula. Note that the Glass Bottle Formula is currently sold by the Alchemist Trainer rather than the Confectioner Trainer.
Thank you,
