Chapter 1第一章

Domesticating Limestone

收服石灰岩

Calcium carbonate is widely found throughout Earth. It exists in rivers and lakes, forms the skeletons and shells of living organisms, and accumulates through natural processes to create tufa, stalagmites, caves, and mountains. The same substance can also be found inside our kettles and water pipes.

From agriculture and food production to glassmaking and cement manufacturing, calcium carbonate plays an important role in numerous industries. Yet much of the limestone used today is still extracted from quarries, transforming landscapes and leaving behind tailings and other byproducts. Could we find alternative sources of minerals within our existing surroundings?

Limescale is one such overlooked resource. Produced through water treatment processes, these mineral deposits are often regarded as unwanted byproducts and discarded. This research investigates how limescale can be reconsidered as a useful material and how mineral residues might be recomposed into substances suitable for building and everyday use through geopolymerization.

This raises a broader question: what would a new stone age look like if cities could harvest their own mineral resources and transform them into new building materials and everyday objects? Could these methods of harvesting and making become integrated into urban systems, gradually reshaping the environments in which we live?

And within this domesticated landscape, how might we learn to dwell with Earth? 碳酸鈣是地球上廣泛存在的物質。它溶解於河流與湖泊之中，構成生物的骨骼與貝殼，也透過自然沉積形成石灰華、鐘乳石、洞穴與山體。同樣的物質，也存在於日常生活中的熱水壺與水管裡。從農業、食品、玻璃製造到水泥生產，碳酸鈣被廣泛應用於各種產業。然而，現代工業所需的石灰岩大多仍來自採石場。大量的開採不僅改變地貌，也留下尾礦與其他採掘副產物。我們是否能從周遭既有的物質循環中，尋找其他材料來源？

水垢就是其中一種經常被忽略的碳酸鈣資源。它是水處理過程中所產生的礦物沉積物，通常被視為不需要的副產物而遭到丟棄。這項研究試圖重新認識水垢作為材料的可能性，並探索如何透過地質聚合技術，將這些礦物重新組合為可以建造與使用的物質。由此延伸出的問題是：如果城市能夠回收自身產生的礦物，並將其轉化為新的建築與生活材料，一個「新石器時代」將會呈現什麼樣貌？這套材料採集與製造方式，是否能融入城市系統，逐漸改變我們的室內外生活環境？在這片經過人類重新編排的地景之中，我們又將如何成為與地球共同生活的居住者？

Chapter 2第二章

Synthesizing Neostone

合成新礦物

Building upon the investigation of urban mineral resources, this chapter turns toward material synthesis. Rather than treating industrial mineral byproducts as waste, it explores how they can become ingredients in an alternative manufacturing process.

Neostone is an experimental material developed by recomposing marble powder, lime pellets, sand, slag, and other mineral residues through geopolymerization. By working with different material compositions, the research investigates how locally available byproducts can be transformed into new stone-like materials, giving unwanted minerals another role within urban material cycles.

Beyond developing an alternative to conventional materials, Neostone also questions the relationship between naturally formed and human-made matter.

By learning from Earth's geological processes and translating mineral transformation into experimental manufacturing techniques, the research explores how the boundaries between natural formation and industrial production might become less distinct. In this way, material synthesis becomes both a practical investigation and a means of imagining different systems of making. 混凝土產業所帶來的環境負擔，促使我們重新思考既有的材料製造方式。工業製程中被視為廢棄物的礦物，是否能透過地質聚合技術，轉化為新的建築與生活材料？此計畫同時是一項材料實驗，也是一種對替代製造系統的想像。研究將大理石粉、石灰顆粒、砂與爐渣等工業副產物重新組合，探索如何讓這些不再被需要的礦物，重新進入城市的物質循環。地質聚合技術並不只是試圖以新的材料取代既有材料，更希望重新理解自然生成物與人造物之間的關係。透過學習地球的地質作用，並將礦物的形成與轉化過程轉譯為人類可操作的製造技術，研究試圖模糊自然造物與人工製造之間的界線，進一步探索工業生產系統的其他可能性。
