Basics

Also reffered to as "Industrial Porcelain Enamel" or "Glass-fused-to-steel" (Technology)
It is essentially a Glass/Porcelain Lining Inside of a Standard Mild Steel Pipe/Tank etc
Thus you have the inexpensive nature of steel, and the high thermal and chemical stability of ceramics/glasses (Re: Borosilicate Glass etc)
Common Examples in a non-technical use would be Cookware and Traditional "Cast Iron Bathtubs"

To Be Researched

Joinery Process:
- Can Welding be Used?
- Or can only Fittings and Cut-to-Length (then Coated + Fired ) Pieces be Used
To What Degree Thermal Shock and thus Thermal Fractures of Glass are an issue
- Although this isn't too difficult to solve then, just need slow Heat Up / Cool Down Periods
Resistance to Etchants / Intensive Cleaning Agents such as Piranha Solution
- Although they may not be used in many cases, in removal of Tars etc solutions like this may be needed
Can Aluminum be coated in a similar way (If so make Glass-Lined Aluminum )
Thermal Conductivity
- Does the Glass Coating Complicate the usage of something along the lines of a Heating Mantle / Hotplate-Stirrer ? In which case an Immersion Heater would be required as well

Hopefully this, along with things such as basic controls like use another process etc, engineering controls like this, and Sacrificial Anodes etc could allow basic metals (Like Mild Steel and Aluminum ) to be used in the same manner as Inconel
- So one could have things like SCWG and various Bio-Petrochemical Reactors be made of appropriate materials (At least somewhat; No Chromium needed etc)
