Ive never had an issue with these in any of my vessels. Ive used them in ceramic, glass and tins. That is until i bought another roll for a HUGE batch of 120 vanila candels with 464 soy in the 8oz tins. I worked with 6% frag load and poured at 135 and even then the wicks were coming loose. My first batch of 12 i poured way too hot at about 165 and they came loose ( also i messed up and doubled my frag to 12% cause i wasnt pay attention to the materials i had layed out in advance. user error i thought). then i refreshed my memeory and poured at 135 with correct frag. Still EVERY one came loose when wax was poured. And all this after wiping the tins with alcohol prior to sticking.
Bottom line is after sticking my wicks i used a heat gun on the bottom for about 5 seconds and then pressed them down held them for a few more seconds. The heat seems to help out alot because my second batch of 24 not one came loose.
take your time and do good prep work and you wont have problems. I think these could use a stronger or more heat resistant adhesive but if you take your time, clean your vesels stick then then heat from the bottom and press firmly that seems to be the ticket.
Not a big deal but i think the common expection is that you stick em and forget em. And rightfully so.
I just dont want to order from somewhere else. The more I can order EVERYTHING from CS the more money i save because i luve close enough to justify the hour drive to the durham warehouse.
But thank you CS for being there for me.
P.S. the aforementioned batch of 120 candles is being donated for disaster relief from huricane Helene and Milton. So the quality of failed stickers was not a total deal buster since i figured out how to make it work. I just cant give away the ones i messed up the frag on LOL
