Cracked piece "From an old cookbook"

[sunray]

"If a cracked dish is boiled for 45 minutes in sweet milk, the crack will be so welded together that it is hardly visible, and will be so strong it will stand the usage as before"

That would have been pyrex....

Just thought you all would like to know so you wouldn't
have to light up that torch
to fix it.. LOL

I have heard that works on hairline cracks in porcelain maybe thats what they were referring to.

I had an alien tech bat check to shit, used it for a while and now that is been dirtied the checks have pretty much been hidden, even after cleaning.....thought it was weird.........should have thought to use milk tho, shucks

all my own pieces i use for myself are checked, and after use the cracks disappear, to the eye at least, it was a strange discovery when i saw my piece that had cracks all the way through it were completely invisible

Boiling? Wouldn't this intense heat just expand the crack? Do you do anything with the curds afterwards?
