The first thing you should have been two quartz and stalker teeth.
The Stalker's teeth can be found in an area full of stalkers, so you must drop a piece of metal debris in one place to attract them and when they finish they will drop the teeth.
When you have the two quartz and the stalker's teeth go back to the manufacturer's base> go to the Resources tab below which you will find Glass.
Use the Quartz to form the Glass, then mix it with the Stalker's teeth to obtain the Enameled glass.
