Cracking a ceramic
filter Steven
Butcher, Alex Crouse, and David Currin
A spring-loaded cylindrical rod was fired downward to break a
ceramic filter, seen from the side. The filter is about the size of a
household sponge and is used in filtering molten metal. This dynamic
method of cracking the filter is one way of testing its strength.
