Hi I always used candlewics wick guide it was helpful BUT when I came up with my wax formula I was going to use I would take all the wicks that might be correct ,I would place them in a large( 13.5" lenth) cake pan, fill the pan with wax and then burn for one hour Then I would have the wax pool size and the depth of the burn for each wax Now then make sure you keep track of which is which and pour the wax about 2 inches deep I hope this helps Jacki http://www.discountsiliconemolds.com
