The rear fire brick for the Blacksmith Bellows replaces the back lining of the firebox. The back brick sits directly behind the main fire and absorbs the highest heat loads inside the stove. It is the most commonly replaced firebox liner, as sustained high-temperature operation causes it to crack over time more readily than the side bricks. ✅ Compatible with: Blacksmith Bellows stove 🔧 Specifications Material: Vermiculite Heat resistance: up to 1200°C Part type: Rear fire brick / back fire brick Replace the rear brick when cracks extend through the full depth of the brick or when the stove body becomes visible through the damaged section. Surface cracks and crazing are a normal result of thermal cycling and do not require immediate replacement. Waiting until full penetration cracks appear keeps maintenance costs low without compromising the firebox.
