Step 1: BUTTERFLY EXAMPLE
For inclusion resin, you need to have a silicone mold.
The quality of the mold allowed to spend less time in finishing.
Weigh the resin and the catalyst to include in. The dosage is really important ! Mix it.... and put half of it in the silicone mold. Before it start to solidify, include the butterfly and add the resin. Adjust.
Let it solidify.
Some hours later, you can unmold.
If the finish isn't what you expected, it's possible to fix it (polishing ...).
