All right, lemme tell you some words and what they mean when used in the dicemaking-world !
Keep in mind that this is not a universal way of working/ doing things, it's just my experience. Everyone does dicemaking their own way, as they should as long as it works for them.
dice : polyhedral, ttrpg dice. Not just d6s used for Yatzee with your Gran (no shade, Yatzee with Gran is awesome, get her some handmade ones for her bday)
dicemaker : a person who handmakes dice; also see "dice goblin" and "dice gremlin".
dX (insert a number for X) : a die with X amount of faces. D6 = a six-sided die.
sharp-edged : most handmade dice are sharp-edged (and some d4 can stab your foes), as opposed to factory-made dice which have rounded corners and edges
spin-down : a die (usually d20) with numbers in ascending order around the die, usually used to track points (health, mana, whatever) in various games.
stabbies, stabby boi : sharp dice that you could commit crimes with
atlernate shapes : new "weird" shapes that differ from the traditionnal factory-made dice; think crystal shapes, clipped corners, elongated shapes, etc...
dice goblin : a dice enthusiast
masters : a 3D-printed model of a die/a set of dice. Most dicemakers sand and polish these up to a mirror finish to make molds with them.
PPE: Personal Protection Equipment; resin is not good for your skin, for your lungs, or any other soft tissues of yours. Nitrile gloves, a respirator with proper cartridges and a well ventilated space are a must for resin work.
molds : silicone molds dicemaker usually make themselves using 3D printed resin masters, there are different styles of molds; most common a sprue molds and cap molds.
resin : what handmade dice are usually made of, it's epoxy resin.
jesmonite / faux stone : a particular type of resin, makes dice that look like actual rocks and stones
a pour, pouring : a resin-pouring session. We mix our resin, our pigments, flex our skills, pour it into our molds.
dice gremlin : a dice enthusiast
silicone : most molds used in dicemaking are made of silicone.
pressure pot : a hermetic sealed type of tank, usually converted by the maker from pressure paint tanks, it's where we put the dice right after pouring to get rid of bubbles in the resin.
compressor : used in tandem with the pressure pot, it allows us to pressurize the pot in order to shrink the bubbles still present in the resin to shrink to undetectable size. Some makers use bike pumps in lieu of compressors.
raw : dice that just came out of their mold. They're uninked, unsanded, unpolished, and might look like they partied too hard.
flashing : not what you're thinking of. It's a thin sheet of resin that forms where the mold connect to its lid, or near the sprue
finishing : the steps after the dice came out of the molds; each maker has their own variant of it.
sanding : first step of the finishing process, the dice are sanded with whatever grit the maker deems appropriate, to even out faces and remove marks and/or flashing
polishing : second step of the finishing process : it turns sanded face back to a beautiful shiny finish.
inking : last step of the finishing process: painting the numbers in
blessing the dice : when the animal of a dicemaker boops the dice in an insanely cute manner, the dice have been blessed
There, now you can actually understand what we're going on about !
Dicemakers, don't hesitate to add to that list, I probably forgot stuff. Others, don't hesitate to ask me if you have a vocab question I forgot about !
