Materials synthesis via liquid-like mineral precursors has been studied since their discovery almost 25 years ago, because their properties offer several advantages, e.g., the ability to infiltrate small pores, the production of non-equilibrium crystal morphologies or mimicking textures from biominerals, resulting in a vast range of possible applications. However, the potential of liquid-like precursors has never been fully tapped, and they received limited attention in the materials chemistry community, largely due to the lack of efficient and scalable synthesis protocols. Herein, w e present the "scalable controlled synthesis and utilization of liquid-like precursors for technological applications" (SCULPT) method, allowing isolation of the precursor phase on a gram scale, and w e demonstrate its advantage in the synthesis of crystalline calcium carbonate materials and respective applications. The effects of different organic and inorganic additives, such as magnesium ions and concrete superplasticizers, on the stability of the precursor are investigated and allow optimizing the process for specific demands. The presented method is easily scalable and therefore allows synthesizing and utilizing the precursor on large scales. Thus, it can be employed for mineral formation during restoration and conservation applications but can also open up pathways toward calcium carbonate-based, CO2 -neutral cements.
