Mortar, Fireclay

Fire clay mortar, while slightly less durable than refractory mortar in terms of extreme heat resistance, offers a more budget-friendly option for projects requiring substantial heat tolerance. It strikes a practical balance between cost and performance, making it a suitable choice for applications like constructing pizza ovens, where consistent high temperatures are expected but the absolute highest level of durability may not be essential. This makes fire clay mortar an attractive compromise for achieving both thermal resilience and affordability in heat-intensive endeavors.

It is made with a 3:1:1:1 mix, measured by volume, of fine mesh sand, Portland cement, hydrated lime, and fireclay.
