Well, I've been making candles for 5 years now. Have done a lot of testing. You get into a rut though and just take for granted sometimes that all fragrances are created equal. They are evidently not. I just recently started purchasing from Peak. They have wonderful fragrances and smell great out of the bottle. I started off with the Clove and at a ratio slightly less that I usually use as I know Clove is harder to wick and it worked fine. I recently bought more Amish Quilt Basil Citrus Cabernet Grape All of them so far have tested with poor melt pool and a I was dumfounded. I do approx 1.25 oz per .lb or a little under. I am thinking that these fragrances are all a little heavier. So.....I am making up pots of 2 lbs with just 1 oz per lb and trying that. Hopefully it will cure the problem. Have any of you found that Peak's fragrances are more highly concentrated than the majority of others? I use AH, Millcreek, CS, CNS and BC fragrances all consistently close to 1.25 oz per lb with the exception of some heavier. WSP I find 1 oz is the norm. I'll post my results after burning tonight!
