How to craft a glyph
Below here are pictures on what a enchanting station looks like and what to expect when you craft a glyph.
When you operate an enchanting station you will have two options. Creation (as seen here above)
and Extraction (as seen below). If you loot glyphs and/or want to deconstruct glyphs this is where you do so. When you deconstruct a glyph you will get either the potency, essence or aspect rune used to create the glyph.
Crafting a glyph requires three types of runes. From this picture below there are three shaped runes. To add runes to the crafting bar either double click the rune or drag and drop to its appropriate shape.
Potency Runes are the purple square runes used to determine whether your glyph will be a positive effect or negative effect. Potency Runes also determine the level of the glyph created. One thing to note on this picture, red runes are runes that are not able to be used until the appropriate Potency Improvement skill is learned.
Essence Runes are the yellowish trapezoid runes used to determine the effect produced from the glyph.
Aspect Runes are the brown circle runes which determine the strength of the glyph created. Ta < Jejota < Denata < Rekuta < Kuta
Once your runes are in place, push [R] to craft and your glyph will be produced.
How to enchant an item
Here is a step by step pictorial guide on how to enchant an item.
To apply an enchantment first you must have glyphs in your inventory. They are found under the miscellaneous tab. Once you have your glyphs in your inventory, find your weapon, armor or jewelry piece to enchant. This item must also be on your character (not in a bank/guild bank, etc). Once you find it in your inventory or equipped, right click on the item as seen in the picture below and click on enchant.
The next picture that pops up is in the middle of your screen, showing what enchantments are available to apply. Hover over the enchantments to view them. Once you know what enchantment you want to apply click on the enchantment it will turn bright blue and then push E to commit and apply the glyph (enchantment).
Now you will notice that my armor piece has the enchantment applied to it. Sit back and now enjoy that extra buff!
Enchantment Type
Special thanks to @Ethoir
Each enchantment type (Weapon, Armor and Jewlery) has its own form ( Pentagonal for weapon, Round for Jewlery and shield for armor) and its own status boost perks (and chance) as well. So every item crafted has its "chance" to receive the full value from the enchantment and has this information on it (though its not visible to the player).
Armor (for the purposes of enchanting) come in two types. Primary and secondary. Chest and Leg armor pieces are "Primary Armors". Wrists, feet, waist, shoulders and head armor pieces are "Secondary Armors"
If you apply an enchantment to a Primary Armor piece, the enchantment's full strength is applied. On the other hand if you put it on a Secondary Armor piece the enchantment loses most of its strength (though an email I got discussing this with the devs gets a bit confusing saying the Secondary Armor pieces have a "chance of a percentage of the full value of the enchantment").
So weapons, shields, and jewelry always get the full effect (with diminishing returns for stacking them on jewelry as far as I recall). Chest and Leg armors will always get the full benefit of the enchantment. All other armor pieces will not.
For Secondary Armor pieces the glyph will always be of weaker output. This much is a fact. However the specifics for enchanting Secondary Armor pieces is that the glyph will only boost the status (Max Health/Stamina/Magicka) by a percentage of its stated value.
For example, a Petty Glyph of Health gives +18 Max Health. If you put this on a belt, you'd get +7 Max Health. This is approximately 38% of the original bonus given to the item because it is a Secondary Armor piece.
Players can never gain more than 50% of the buff from a glyph if it is used on a Secondary Armor piece. The percentage you get varies based on your character's level, your enchantment level, and the level of the item you are enchanting. So this leads to some really funky numbers for enchanting non-primary armor pieces.
Double Enchanting
*Currently not available in game* left in the guide in case the bring it back.
As far as I have learned (correct me if anyone finds otherwise). To double enchant an item the current item must have a lock on it and if a weapon or armor piece must be upgraded to at least purple or better gear level. An item with a locked symbol cannot have its enchantment changed to a different one, but can however have a second enchantment applied to that item. Jewelry can have a double enchant placed on it as long as it has a lock symbol on it. Until they implement upgrading of jewelry I do not see this feature changing until then. Here is a picture below of an item with a double enchantment.
