Can stone outdoor ottomans be used as outdoor kiln foundations?

Stone outdoor ottomans are popular for their durability and aesthetic appeal, but can they double as foundations for outdoor kilns? While stone is naturally heat-resistant, not all stone ottomans are designed to withstand the extreme temperatures of a kiln. Factors like thickness, composition, and construction quality play a crucial role. For a safe and effective setup, ensure the stone is dense and free from cracks. Always test with low heat first and monitor for stability. For heavy-duty use, consider purpose-built kiln foundations instead.
