A comparison was made of the ability of different impression materials to depict precision made steel blocks. Stone dies poured into such impressions were studied concerning their hardness, dimensional accuracy, detail reproduction, and surface reproduction. The dies were produced in the impression material only to a small extent, with the exception of their surface roughness. Differences between impression materials are otherwise small. The advantages of two-phase alginates over standard alginates lie in the impression technique rather than in the characteristics of the material.
对不同印模材料描绘精密铸造钢块的能力进行了比较。研究了灌注到此类印模中的石膏模型的硬度、尺寸精度、细节再现和表面再现情况。除表面粗糙度外，印模材料对模型的形成作用较小。不同印模材料之间的差异不大。两相藻酸盐相对于标准藻酸盐的优势在于印模技术而非材料特性。
