We reported here last year on the death of Stanley Sporny (see November 4 post) and, at the time, we didn't know whether his Sporny Solutions formulae might have been lost.
We're glad to say that the products will still be available. For anyone who is concerned about toxic fumes or wants to extend the working time of their paint, these materials are the answer. They contain no volitile organic compounds or citrus. The mediums are professional grade, non-yellowing and archival. The clean-up solvent doesn't evaporate and can be re-used many times.
