The answers above are correct, but you may be going through the same sort of confusion that hit me when I started crafting. The problem is that the names of many crafting materials as they appear in the recipes are only rough approximations of the crafting materials that you find while harvesting.
If you search the broker for "raw glowing material," you won't get any results. Instead, run a search on "glowing stone" or "glowing scale." That should do the trick for you.
The same goes for recipes that call for other raw materials, e.g. "raw coral" is really "rough coral" and "raw elm" is really "severed elm".
