for years now I have used 1.25 to 1.50 per pound if 415 . Last week after reading all these I made one of each of my year round scents in 8 oz jj and 1 of each fall scent in 9oz melting pots using 1 oz per pound. The burn was fine . The same as with the amounts I used in the past. no better no worse. The HT not the same. Don't get me wrong i could smell them but no where near the amount I could before. I didn't wait an entire week at first but closed them up and tried again now a week and two days later. I have had candles burning in every room in the house with doors closed. My family thinks I am nuts( might be some truth to that) I figure if the burn didn't change it may just be a matter of opinion on how strong you like your scents. Since I can still smell them burning I guess it wouldn't be that the FO or the company you get them from is not as good. It may be just a matter of opinion ... how strong you like your candles The way i see it here on this thread people who answered... 6 people use 1.50 ,5 use 1.00 ,4 use 1.28, 2 use 1.60 and 3 use .96. now if you are having trouble burning them then I think you have to adjust. I would love to go down to 1.0 . that's a great save . I will seal them up and try again next week . I need the strong throw:cheesy2:
