hi all ,  using glasscast resin how do i  prevent the piece from looking dull and misty on the side that is inside and making contact with the actual  white  melamine mold,  which is the back and the edges      the top is fine clear and glossy  . also something i cant fathom is the extra resin i have by mixing too much  i pour into a plastic disposable  cup (left to set and used for turning on the lathe at a later date) which  is easily removed from the cup and is glossy all over .. also  to repeat the process to make multiple objects  what liquid  silicon molding material  should i use to have a reusable mold .... and would the piece come out glossy all over . help  needed signed willii
