ok i was on late one night crafting fossil tempers made about 60 and then decieded to sell them to other players on the market so i soldedm for 2c a piece then went to bed woke up next mourning and the had all sold.
Another thing to consider, and it is usually much more profitable, is to check the price of your materials such as roots and woods, i recently found that i could sell my roots for WAAAAY more than i was getting for my extra vials of resins and tempers.
