First thing,,Hello and Welcome to CT!! Can you tell what wax it is,,soy, paraffin??? If Paraffin yes you would heat your wax to around 180 then put in your pour pot,,add Dye if coloring them,,then FO,,and I pour my Tarts @ 175...Now for the ones you say you poured hot,,how do they look? Are they smooth? It is best if we know what wax you are using to really be able to help,,, For curing,,you take them out of the molds,,I wrap mine in a cotton hankercheif and set them in a dry dark place for 24 hours and then I test burn them. You really do not usually need to put them in the feezer to un mold them,,try letting them cool all the way and then un mold them. Im sorry I keep editing this but I am trying to answer everything,,, But please what wax are you using,,Thanks,,I want to help
