I’m looking at how the hardness of gypsum stone surfaces is influenced by different impression materials. It seems certain materials like alginate can produce softer stone surfaces because they absorb water, which lowers hardness. Additionally, alginate and agar can retard gypsum setting, possibly reducing surface hardness further. I’m curious about how elastomeric materials, like addition silicones, might release gas. However, I don’t think they directly affect hardness as much as the alginate does.
