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).

Best,
Keewook
