Muffins In A Glass -- With Used Jam-Jars?

[gl556tr]

I have chanced upon this recipe which utilises glass jars instead of the usual baking tins.

The recipe points out that any screw-top, glass jars that one would otherwise throw away could be used.
I expect that warming such glasses in very hot water, before popping in the cake-mixture should survive the oven session.

Or has anyone had experience with exploding glass jars in their ovens?

Thank you, in advance.

***from the author of the original question***

After burrowing through all the quips, the links are interesting and I will use them for reference.
The recipe is in German. Suffice it to say, that the picture with it shows the muffins having survived a bake! (zey haff vays unt meenz ...) 180°C for 25 minutes.
Oiling the insides of the glasses and adding crumbs avoids sticking. Then simply eat out of the glass.
Don't tell a Russian; he'd likely throw his over hi shoulder.

Should I survive, I will tell you of the trials and tribulations I had to endure. Now with true English robust spirit, I will begin this endeavour which will, of that I am certain, go down in English history. 'Hurrah!' stage left. But don't tell the Germans.
