Dear all, It is not hard to make customized mold using teflon at the machine shop. Our owns are working well with Epofix (Struers), 105 resin-206 hardener (West system) and EpoxyCure (Buehler). I attached one image of one lab-made mold + three groups of zircon minerals (~150 grains each) + double-side tape + glass plate (top view: before pouring epoxy resin).
