Sorry, refunds or exchanges are not provided for damages to the mold after usage!Please understand that silicone molds are only heat-resistant up to 450°F (232°C). Silicone molds have a risk of adhering to your resin piece if too much heat was applied to remove the bubbles. Do not use a torch to pop the bubbles as this will damage the mold. Unless a vacuum chamber is used, there will always be a few small bubbles! The best way to minimize bubbles is to warm the resin before mixing, and mixing slowly with a plastic stirring stick (it is not recommended to use wooden craft sticks as the porous surface creates small bubbles in the resin). Use a straw to blow the bubbles away, or use a regular BBQ lighter and do quick passes over the resin (do not stay in one place as this will overheat the resin and damage the mold). While not necessary, using a mold release or rubbing baby oil onto the mold is also a great way to protect the mold and help preserve the shiny finish!
