I cut and drill all dice by hand and not by computer (CNC). Wood, being a natural material subject to varying growing conditions, is prone to having uneven density throughout (especially in multicolored woods). Because of this- it should be expected that there will be some variation in pip alignment and corners (even in A-Grade or Exhibition Grade Dice it will never be perfect). I do my best to make everything precise, but sometimes it cannot be helped. Each dice is inspected thoroughly and graded accordingly (explained below).
Outside of dice used by Las Vegas casinos, no dice (wood, resin, metal, gem stone, etc) are perfectly balanced. Balancing cannot be done with natural materials regardless of if the die is cut by hand, cut by CNC, or cast in resin.
Exhibition is the highest quality of wood I offer. Consisting of the most unique pieces I can source. Rarity of the wood does not necessarily come into play, even common woods can qualify. They will be more expensive than the standard/average pieces of each wood type.
A-Grade pieces are pieces that meet the average expectation of what the wood and workmanship should look like.
B-Grade dice are ones that just didn't come out right aesthetically. B-Grade dice will be ones that have a pip that came out uneven, or may have even had a crack that needed repair- but there is nothing significantly wrong with the dice where it can't be used fairly in a game. There will be a %15 discount for these.
Burl wood is unsprouted bud tissue on a tree that can be cause by injury or disease or even genetic defect. Where normal wood grain runs more or less parallel to the tree- burl wood curves and folds and creates patterns reminiscent of Damascus steel. It is the most sought after quality of timber and is the most expensive type of wood (relative to the standard lumber of the same species)
Spalting is a discoloration or figure in a wood generally caused by a fungal infection. The discoloration is basically the trees version of an immune system causing inflammation to fight the infection. The figure is black lines that often look like lightning bolts running through the wood, which is more or less the path the mycelium of the fungi took through the wood. Spalting can happen to both live or dead wood so the pattern variation is incredibly high.
Certain woods go through a process called stabilization which can both help them retain color and hold together if there is degradation to the piece (usually from spalting). This process involves the wood being soaked in a resin bath, put into a vacuum chamber to pull the air where the volume taken up by that gas is replaced by the resin when pressure is released, and then baked to harden the resin. These pieces will generally be very smooth, very hard, and very durable.
