Problem description:

My kettle is flat and ugly.

How can we handle it simply and safely?

Is boiling water okay?

Analysis:

No, it's impossible to produce that much tension ~ ~

If it's a wide mouth, it may be easier to repair it with a small hammer ~ ~

But if it's narrow, I'm afraid it's difficult ~ ~ Even a very complicated process can be repaired ~ ~ But it's not worth the loss when it's used in the civil field ~ ~ You can use the closed pressurization method ~ ~ that is, pour the liquid in and pressurize it ~ ~
