:cry: Hey Peeps! Have tried and tried to produce Pate de verre, so many times and using so many colouarnts and quite how ANYBODY can achieve it successfully, still baffles! The modern-day compounds undoubtedly use a Borosillicate, to bind the ingredients (whatever they may be?) and unlike the lost-wax making process, metal molds are re-used. This LABOURIOUS technique, requires more than just skill or a working understanding of "glass!" I think it best left alone and a part of our history! Far better perhaps, to develop NEW working mediums/methods, rather than to copy or to ape The Masters, such as Gabriel Argy Rousseau and others... Unless of course we are talking about cire-perdue, which we all of us know is a piece of cake to master! lol :spls: Jazz
