Mold wall in place

Box secured with hot glue, which will peel away easily from the acrylic after the silicone cures overnight. There isn't any mold release applied to the master for this mold – in order to get a perfectly shiny surface, the master was prepped with automotive wax before molding. A spray on mold release will slightly change the surface property of the finished mold, making it pebbly instead of smooth.
