I watched the video at the expecting one thing and finding something completely different. Remarkable — [0] watch the video in its entirety. Not what I thought when I read “staples to repair porcelain”.

Wow - beautiful.

I've mended a lot of porcelain and earthenware but I use the modern art of epoxy resin. The tricky bit is letting it set just enough so you can cut the excess off cleanly without smearing but not too much so you can't cut it all the while keeping it under enough tension.

I like the string tensioning in the video - think I'll try that on my next mend. I normally use a set of small clamps but it is difficult to get them very tight.
