Story
The natural stone industry, as exemplified by the Lithuanian company Akmenstata, generates a substantial amount of waste (approximately 8m3 per month) in the form of edges, offcuts, and small pieces. While a portion is used for road fillers, the majority, deemed non-toxic, has the potential to be upcycled. Designer Agne Kucerenkaite, collaborating with Akmenstata, combines stone with ceramics, exploring innovative ways to connect them without traditional adhesives. This playful project not only considers the inherent properties of each stone, including chemical analysis and melting points, but also aims to transform waste into an eco-friendly surface collection.
The project's investigations reveal quartzite's and limestone's capacity to substitute conventional silica, and travertine's potential to replace calcium carbonate in ceramic glazes. Consequently, the project aims to recognize the stone post-firing by embedding it within ceramics. Granite and quartzite have demonstrated resilience in retaining their structure and form even under high temperatures. Of particular intrigue is granite, enriched with iron, its hue determining its content. Iron, a recognized ceramic colorant, can reduce the melting point in ceramics when present in higher concentrations. The outcome manifests as a scalable surface tile collection enhanced with quartzite and granite inclusions. Black granite undergoes a fascinating transformation in ceramics, forming intricate flower-shaped structures.
The Stone Waste is Bliss project originated from a mutual commitment to sustainability and efficient resource utilisation. Through methodical research, hands-on experimentation, and a comprehensive approach, the aim is to bridge the gap between discarded materials and functional, aesthetically pleasing pieces. The use of natural stone in interiors has a long and rich history. Stone has served as a building material for thousands of years, dating back to ancient civilisations like the Egyptians, Greeks, and Romans. Today, the use of natural stone in interiors continues to be popular, with a wide range of options available. Natural stone is valued for its durability, timeless appeal, and the unique character it can bring to a space. In the context of Stone Waste is Bliss, preserving historical significance within a modern framework holds great importance. The concept finds its foundation in the combination of practical craftsmanship, a commitment to environmental responsibility, and a vision to advance the principles of circular design. The project aims to set an example for other industries, advocating for healthier materials, reduced waste, and a more sustainable built environment.
