Large Porcelain Plate - Hand Painted Flowers

Another of my treasures that has been packed away is a beautiful, large 12 5/8" diameter HAND-PAINTED VICTORIAN ERA DECORATIVE SERVING PLATE. At lease I am assuming it is from the late Victorian Era. The plate is in a warm cream colored glaze and has a slightly scalloped rim with a raised stylized floral and leaf border. The outer edge of the plate looks like it has tiny fissures but it is a glaze or paint. The plate border looks almost Art Nouveau to me. In the center of the plate is a beautifully detailed hand-painted bouquet of brightly colored pansies in shades of yellow, purple, red, white and dark pink. It measures about 1 1/2" in depth. This fabulous piece is signed on the back B. v. (von) MOTZ.

I believe it is porcelain. Which brings me to another question. Would people have actually used a hand-painted platter to serve food on or would it have been more of a decorative Cabinet Plate? It seems the painted floral design would eventually fade or come off from use if that were the case.

Could it be a transitional Victorian/Art Nouveau piece? As always, I look forward to hearing back from those much more informed than I regarding porcelain, pottery and china.
