So, here is what the patch notes says on getting the glass motif:

Glass Style Motif
The secrets to crafting Glass arms and armor have begun to be revealed!
You can learn to craft in the Glass style by finding the Chapters or the Book for it. These Chapters have been torn into unreadable Fragments by the ravages of time and travel, but can occasionally be found slipped into the Writ rewards for Blacksmiths, Clothiers, and Woodworkers.
Once you’ve gathered ten Fragments, you can reconstitute them into a readable Chapter (or, if you’re exceptionally lucky, the whole Book) with some Merethic Restorative Resin.
This Resin is sold by Mystics around the world for a hefty price.
You must be Rank 10 in the Metalworking, Tailoring, or Woodworking passives to understand the style’s intricacies and learn it permanently.
You’ll also need some Malachite to actually craft an item in the Glass style.
Malachite Shards can be found in Treasure Chests around the world. Chests with more durable and difficult locks are more likely to contain them, but the chests that require a Treasure Map to find have the best chance by a wide margin.
Once you’ve collected ten Malachite Shards, you can refine them into a single chunk of Malachite at any equipment crafting bench, but know that this will bind the Malachite to your account, making it untradeable.
Once you know the style and have the materials, you can craft Glass gear at any equipment crafting bench.
Here is the tool tip you get on a Malachite Shard in-game: "Ten of these items can be refined into Malachite, which is used to make Glass equipment. Doing so permanently binds the malachite to your account.
So here be my thoughts:
I feel like ZOS is playing this Glass Motif situation in the mindset of the cash shop, and here is why.
First off, it took me FOREVER to get the Malachite Shard, so right off the bat the required material is a challenge to get. Along with this, in order to learn the crafting recipe, you need to collect the fragments, which you only have a shot, not guaranteed retrieval, of getting each day, and you need 10 of these in order to get a chapter to learn how to craft one thing. And, to further this, you need to do it several times in order to learn it all, or you get REALLY lucky and get the book when you combine 10 fragments, but if its like the Dwarven motif there is a damn slim chance of that. Along with this, the Resin to restore the fragments costs 25k gold, so you need to pay that each time you get 10 fragments.
So where does this bring us, to summarize above, it is a difficult challenge to get the malachite to craft glass armor, but even more so of a burden in order to craft the whole motif itself, seemingly a task that will take days.
Now, I want to say I have no problem with things that you need to work towards earning, but I suspect a cash shop trick here, where ZOS will let you skip the grindy process of getting the glass motif racial if you buy it in the crown store, basically enticing people to buy it based on the challenge and the pure repetitiveness of the grind to earn it, as it seems like it will be even more challenging to get than the Dwarven motif, as like I said, you only get three shot a day at a fragment.
So, I personally think that they should avert from this course, if this is truly their plan, or as an alternative to go along with this, I have come up with a potential better solution:
So, the glass motif is supposed to be an ancient art form that was lost to time right? In that case, why not have there be a slim, slim, chance to learn or earn some fragments while exploring ancient ruins dotted around the landscape. I would imagine that if it is ancient knowledge, it might be able to be found in bookshelves, as bookshelves usually contain books, and the glass motif is all in all a book. So, again, I think it would be fair if, while exploring ancient ruins, there is a slim chance that players might be able to pick up a fragment of the Glass Motif while checking bookcases inside of say an Ayleid ruin. This would enable players a second winded chance to get fragments, if they don't get them in crafting writs, so it is not as much of a punishing grind. And like I said, this could be a slim chance, maybe even rare than getting Dwarven chapters from pots in Dwemer ruins, but at least it would give players another chance at working towards crafting the motif book, rather than just a slim chance three times per day or needing to outright buy it for real money, if ZOS really is playing the cash shop game.
Anyway, those are my thoughts.
