All of the fire brick and refractory mortar came from Larkin Refractories in GA. Stovemaster suggested Larkin, but it was my call. Ironically, the firebrick were about the same price as they would have been had I gone through a local brick yard. Yes, the core used refractory mortar and regular stuff was used on the common brick and stone. Part of the design includes very detailed instructions on every aspect of the build. Alex is also available via phone and email for questions. The mason working on the build has consulted with him regularly to make sure he was getting things right.
