Short answer is no.
Jesmonite is an eco-friendly safe alternative to resin, plaster and concrete. It comes in 2 parts, a mineral based powder which is gypsum based, and a water based acrylic liquid. When combined they have a thermodynamic reaction and hardens to the shape of its container. the perfect casting material.

Jesmonite is water-based, making it gentler on the environment, and my lungs.

Jemonite source ingredients through local supply chains to keep CO2 emissions and carbon footprint to a minimum. I source my supplies from UK based companies as much as possible.
