A favorite of professional sculptors, ROMA Plastilina is an oil- and wax-based modeling clay that is permanently pliable and, in fact, becomes more workable with age. ROMA Plastilina No. 1 – Soft is primarily used for modeling monumental (large) sculptures. It is easily scraped from molds.
As this Plastilina does not contain water, it will never harden; and is not adversely affected by heat. Contains sulfur.
At its introduction, in the early 20th century, and based upon Italian formulations, ROMA Plastilina was and continues to be a wax- and oil-based modeling clay made with sulfur. The sulfur gives the Plastilina that extra smoothness and flowing ability that professional sculptors did and still do require in their clay. Both its proprietary formula and manufacturing process for ROMA stand today.
Due to the wide variety of new and advanced mold making compounds, such as Silicone and Platinum Silicone, please note that some of these mold making compounds may contain chemicals that may not be compatible with sulfur. To avoid any complications with the mold making and casting process we suggest that you apply, either by brushing or spraying, a thin coat of separator to the clay model first. For example, you can use a crystal clear aerosol spray or shellac cut 50/50 with denatured alcohol. With this step, you should be able to avoid the adverse reactions to some of the chemicals in the mold making ingredients.
If you have any questions about the materials chosen for your mold making and casting process, we strongly suggest that you contact the manufacturer of that material and ask about its compatibility with a Plastilina containing sulfur. And always, test your mold making and casting materials on some of the ROMA before tackling the complete project.
