D&D Dice Making / Green Dragon

Hello
When playing Dungeons and dragons, my absolute favorite dragons are always the green ones. Maybe it's because of my love for Cyan Bloodbane in this dragonlance series. In the DnD universe, green, red, black, blue, white .. colored dragons are usually evil, but those with colors such as gold and bronze are usually benevolent.

Green dragons don't blow fire, instead they blow a kind of acid that dissolves everything poisonous. That's why I call these dice green dragons. It reminds me of the poisonous acids of green dragons.

While making these dice, I used Epoxy resin and molds that I made myself. Earlier I talked about my problems with bubbles on the dice. I actually have a bubble problem with these, too, but these dice were definitely the ones with the least. That is why I love you. It's her favorite color and the one with the least bubbles. :D I have 2 of this set. I will definitely keep a set for myself. I have many suitors for the second set :D

So why less bubbles? What did I do differently?
The problem is, I don't know the answer to these. I didn't do anything different than usual. I have no idea why there are not bubbles this time.
