This talk addresses persistent tangles. These are tangles whose presence in a knot diagram forces that diagram to be knotted. We provide new
methods for constructing persistent tangles. Our techniques rely mainly on the existence of non-trivial colorings for the tangles in question.
Our main result in this article is that any knot admitting a non-trivial coloring gives rise to persistent tangles. Furthermore, we discuss when
these persistent tangles are non-trivial.
