Very unfair to clay liners, some of which are intact after 75 years of operation. You used "thermal shock" on a cold clay liner, and of course, it fails. Start a small fire and let her warm-up for a while.
Although every chimney should have a stainless liner, the tile used here and all other testing showing the same thing is bare. There is nothing surrounding the tile, like sand or an inch air space. There is nothing helping/stopping the tile from expanding to much. The tile will definitely break if not warmed up properly. There are a lot of circumstances that will crack tiles. The biggest one is a chimney fire, but that can be avoided with an annual chimney cleaning. Chimney tiles properly installed and treated properly are just fine.
Cuz they never do, only on this video and done on purpose to sell u fear...but yes a liner is a good think to have, then fill the gap between the liner and the old chimney with rockwool

Wow! I didn't know that a terra cotta liner could break so easily from a creosote chimney fire!
