During the process the essentia will be automatically drawn from the jars etc. Then you have to right-click on the runic matrix with your wand and it will start the infusion. Providing extra is safer, because instability or other factors can add to the 'official' cost. For the recipe shown 9 of each primal aspect and 9 Praecantatio are required. This can come from any sort of essentia container, and can also be relayed by way of essentia mirrors: Jars ( warded or void), reservoirs, or mirrors need to be placed within 12 blocks of the Matrix, but these do not have to be symmetrical. It is also necessary to supply the essentia needed for the recipe. Note the empty pedestal: Even with an odd number of ingredients, it's better to balance the pedestals. The first step is placing the target (a silverwood log) in the center of the altar, then placing the other ingredients on pedestals surrounding, maintaining symmetry as best as possible. The picture on the right shows an infusion setup for creating a silverwood wand core. Note that while instability can knock off or destroy items on the outer pedestals, it will never affect the target item. This will produce one final burst of instability effects. If an infusion is getting out of hand, or just mysteriously stalled, it can be aborted by removing the central (target) item from its pedestal. Warning: The active instability can increase over the course of an infusion, but never decrease. This is completely normal and will not cause any further instability or problems, it's purely graphical and will not influence your altar. Note: While instability can be countered with candles and skulls and such, more stabilizers will result in the runic matrix moving more during the infusion. This allows plenty of space to place stabilizers, often in a 'candle room' below the altar. Stabilizers must be within a range of five blocks above the matrix, ten below, and 12 blocks in each horizontal direction. Stabilizing items include mob or player heads/skulls, tallow candles, and crystal clusters. (Same Y coordinate, but with opposite distances in X and Z.) Unmatched items will increase instability. Pedestals, ingredients, and stabilizers must be paired, across the altar, with radial symmetry.

Certain magical paraphernalia reduces the instability of the altar however, the placement is important. For this reason, it's important to reduce instability by all means. Instability can cause bad things to happen, such as items being knocked off of pedestals, or as far as releasing flux into the environment. In the Thaumonomicon, an instability difficulty is listed at the bottom of the infusion recipe, from negligible to dangerous. This page gives a casual overview for more detailed information, see Infusion mechanics. The items do not need to be placed in a particular order around the altar, however it is imperative to keep as much symmetry as possible. The process requires an Infusion altar, surrounded by two to twelve pedestals, which will hold the items to be infused. Infusion is the process of binding items and essentia to a central item to change its properties.
