Scottish Photographic Federation
Founded in 1903, the Scottish Photographic Federation (SPF) is a non-profit-making body which includes in its objects the discovery, promotion and protection of amateur photography throughout Scotland, and is the only body recognized by international agencies as representing the interests of Scottish Camera Clubs on a national basis. Most Scottish Camera Clubs are affiliated to the SPF and thus participate together, and against each other, in inter-Club, National and International Competitions.
I apply these paints in small plastic bottles and add a metal tip to outline and apply. The only thing I dislike is you never know which color will change to a different color after baking. Mostly I use the Pebeo 150. I find they do not change color after baking. Another problem is they do not have it in white,first time I used what looked like white, it turned ivory and even looked more yellow than ivory. I just wish there were more art suppliers who carry it. Most of the time I order it.
I used Porcelaine 150 about 14 years ago on some glasses; they have been washed over and over in the dishwasher, and the color is still bright and beautiful. I did bake them in the oven as the directions specified. This is a great product!
