Thanks a lot for your feedback
I used [commercial link removed]. The website is in german, but to sum up, the cement is used in blast furnaces, able to withstand 1600 C (2912 F) and can store heat.
The cement is recommended by many people from german blacksmithing forums, so I have high hopes that it will work as expected.
Good to know, thanks . True, all images of forges I saw so far either put the burner in the middle or closer to the opening.
I intentionally put the burner in the middle of the forge, but because I did reduce the size, the burner moved back in respect to the interior room, unintentionally.
Thanks .Im planning to forge blades and tools (tongs), maybe axes one day, damascus steel would also be interesting. Yeah, definitly using a firebrick for the floor, especially when forging damascus.
Going to take a look, thanks .
I tried running my new burner, but sadly, it doesn't get enough oxygen. Probably have to enlarge the air intake.
Best wishes
