Abstract
Exemplary embodiments of mud gun caps are disclosed herein. An exemplary mud gun cap includes a flame-resistant body that has a tap hole contacting surface. The flame-resistant body has side wall; a first bore and a second bore located within the flame-resistant body. The first bore has a first diameter and second bore has a second diameter. The first diameter is smaller than the second diameter and the second bore is located farther away from the tap hole contacting surface than the first bore.
