Disenchant Magic Item
There are many ways to Craft Items, magical or otherwise. When it comes to Crafting a Magic Item there are many routes as well.
One is very complicated and hit-or-miss where you need a formula, time, money, and items—this is the traditional 5E by the book crafting. Crafting Magic Items
There is a system where one creates focal stones and through a complicated, time-consuming and expensive process enchant items. Crafting Magic Items with Focal Stones
There is another system of Gem Magic where you can enchant gems and then use sockets to change the enchantment as well. Crafting and Using Gem Socket Items
from comp. item book: DISENCHANT MAGIC ITEM 1st-level transmutation (ritual) Casting Time: 10 minutes Range: Touch Components: V, S Duration: Instantaneous You maintain contact with the target common or uncommon magic item for the duration of the spell’s casting, at the end of which its magic is destroyed, along with its seed, turning it into a quantity of essentia equal to half the magic item’s value. The pulpy, magical substance appears on the ground at your feet or in one or more indicated containers on your person at the spell’s completion. The physical form of the item remains unharmed but is now completely non-magical. When calculating essentia, do not count an item’s additional value based on its physical form, like the cost of plate armor or the gold value of a magical crown. Only the base magic item value, plus the value added by special features, affects the resulting amount of essentia. This spell cannot recover essentia from any magic item that did not use essentia in its crafting. This typically applies to quasi-magical items, healing potions, and some artifacts. If this spell is used on a sentient magic item, the magic item has the option to cause the spell to fail, depending on its own interests or whims. This spell will not work on an item that has a mystical connection with a creature, whether by attunement, the bond of a warlock’s pact weapon, the magic of an active curse, or some similar effect. The connection must be severed before the spell can have any effect. At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can affect a rare magic item. When you use a spell slot of 6th level or higher, you can affect a very rare magic item. When you use a 9th level spell slot, you can affect a legendary magic item.
Residuum & Magic Item Crafting
And here we explore a different system utilizing Residuum. With a bit of Residuum it is possible to create a magic item or upgrade other magic items. It is always a risk and still takes a bit of time, but nothing like the other systems. If you have just a bit of Residuum you can create more of this important dust and then use Enchant Magic item to create or upgrade your own items. This is currently a lost form of crafting, if used it is still done in secret. Historically when magic was too easy to obtain or manipulate it led to issues. Governments feared people rising up and the people feared governments using these to control them too easily. So, if anyone has access to these spells or how to use them -- it is a very well kept secret. -----------from comp. item book: DISENCHANT MAGIC ITEM 1st-level transmutation (ritual) Casting Time: 10 minutes Range: Touch Components: V, S Duration: Instantaneous You maintain contact with the target common or uncommon magic item for the duration of the spell’s casting, at the end of which its magic is destroyed, along with its seed, turning it into a quantity of essentia equal to half the magic item’s value.

Effect
Casting this ritual allows you to turn a magic item into residuum. When you touch an item after casting this ritual, you destroy its magic but leaving a plain item. The magic item ignites in a brief flash of brilliant light, then leaves a pile of silvery or golden dust in your hands or on the item, turning it into a quantity of residuum valued at 1/5 of the item’s price (based on DM's pricing).
A magic item can only be disenchanted by casters with a spell casting level that matches the rarity of the magic item according to the table below. (See chart below)
