Two vases from the extensive Johansson collection in Berlin. The one on the left is depicted in the 1897 Vilmorin catalogue and was made by Legras; the one on the right is from the same mould. Height, weight and diameter are identical. Obviously the colours are different; the first one was made, cooled, enameled, fused, annealed and then struck at the glory hole. The second was made, annealed and struck - so less temperature change. The final "strike" operation in which the colour changes from transparent amber to dark red is difficult to control, hence the colour gradient varies per piece.
