Creating Heat Shock on purpose?

[Totopo]

Hello Community! :-)

I am pretty new to ceramics and I am learning new things about this fantastic material on a daily basis.
For my latest project I am trying to crack/break up old clay bottles with the principle of the heat shock. 

Does anyone have an idea what would happen, when I rapidly heat up a bottle (like the one in the picture) to
1800 degrees Fahrenheit ? My wish would be to let the bottle explode and to create many fragments.
Is the wall of the bottle maybe too thick (approx. 4mm) to really burst into pieces? Will nothing happen or 
maybe just one big crack? Or does anyone have an idea how to make the shock/explosion bigger ?

Thank you so much for your help!

Y? Just curious-I have no clue.

You could always drop it on the floor, that tends to make them explode no matter what stage of firing they're at

Clay by itself does not explode. Water turning to steam (at 100C/212F) can cause a clay vessel to explode. A raw clay object that has not dried will explode from the steam and fragments will be found throughout the kiln. Once the water has dried, it will  not explode. There will be a time at around 900F that a very thick piece of clay will break due to creation of new water at the time of ceramic conversion of the clay, but only if the exterior surfaces are sufficiently hotter and the surface has sintered and sealed over, trapping the new water deep inside. Even then, it is not an explosion, merely a spalling of chunks off the side. If a bisqued piece, which is still absorbent, is saturated with water (such as from glazing) and fired before it dries, another steam explosion will occur. But if it has been successfully glaze fired, it is improbable that you can saturate enough water into the now-vitrified ceramic that it would explode if it was fired yet again. It will very likely crack from the steam, but probably not a spectacular explosion as you seem to want.

is there a reason you want to ruin a perfectly good antique that someone else would treasure?

(Or does anyone have an idea how to make the shock/explosion bigger)

fill it with black powder and a long fuze light and run-it will be much bigger thermal shock.

The idea is to blow glass inside the bottle and not destroy the old bottle but let's say extend it. 
So in the end I would love to have a glass bottle with pieces of the clay stuck in it. It's more of a
conceptual approach behind the idea. @oldlady the bottle is not an antique, you'll find them here
in the Netherlands everywhere. 

So the hot glass should resolut in the thermal shock. Do you think this is anyhow possible? Thanks so much!

Maybe if you froze the bottle directly before blowing glass into it.  Using dry ice or something that will super chill it

Glue chicken-wire to the outside and smash it? Maybe different types of wire?

I'd pre-heat the bottle to blow into it, then shock with cold, maybe just pressurized air, to breach the clay.
