I make molds of the babies and children in our hospital that don’t make it. Babies that are born still or die shortly after birth and children who we are unable to resuscitate in the ER. This product is strong and holds up even on the smallest of babies. The youngest one was just 12 weeks gestation. This is a four year old who drown. This is the last memento that the family will have and this holds up so much better than plaster of Paris. ### ⭐⭐⭐⭐⭐ Hydro stone for Jewelry container *by on Reviewed in the United States February 16, 2026* I bought this hydro stone for a jewelry container and it came out nice ### ⭐⭐⭐⭐⭐ Great Product! *by on Reviewed in the United States July 29, 2025* I love Hydrostone so much!
