Next to the two shades of blue, the colour most frequently found on Egyptian glass is a yellow, at times of a full mustard tint, but more often of a paler hue. Feather-like curved chevrons of this colour, combined with turquoise and opaque white on a deep blue ground, constitute indeed the normal type of decoration in a whole series of these little vases. I can find no record of any analysis of this yellow colour, but we may well compare it with the fine yellow glazes of the Chinese where the colour is derived from a mixture of an ochry earth with an oxide of antimony. There is no doubt that this last metal was known to the Egyptians; it was used at an early period by the women to darken the outline of their eyes.[12] What has been said of the colours used by the Egyptians applies equally to the whole series of this primitive glass, indeed to a large extent to the glass of the Romans as well. It will form, I hope, a solid introduction to the subject generally. The little vases or _unguentaria_—by far the most important objects in this division of our subject—occur in Egypt in two forms. First, the true columnar kohl-pots, spreading out at the top in the form of a lotus capital. Secondly, globular jars with a pair of small handles: these jars are sometimes flattened at the sides so as to pass into the shape of a pilgrim’s flask. In a little vase of this latter form in the British Museum the paste is of a deep, somewhat translucent, brownish red (Plate II.), and this colour passes in other examples into a rich transparent honey-red or hyacinth tint. The colour in both cases is, I think, derived from iron. Of quite exceptional interest is the little vase in the British Museum, bearing the _prænomen_ of Thothmes III., painted in yellowish enamel round the shoulder. I say painted, for in this case the decoration is simply applied to the surface, and not incorporated into the glass, thus forestalling the later processes of enamelling upon glass. The vase in question is somewhat rudely formed; it is of an opaque paste of a remarkably fine turquoise hue, and the sides are decorated with three conventional trees also in yellow enamel. This vase has been regarded as the earliest dated specimen of true glass that is so far known to us.[13] The British Museum has lately acquired a curious vessel of glass, five inches in height, somewhat of the shape of a Greek _crater_. The wavy, dragged decoration on a pale slaty ground calls to mind certain early vases of wood or stone _painted_ with a similar design. This vase, together with a cup of azure blue transparent paste, comes probably from the tomb of Amenophis II. Another little vase in the same collection, of _aryballos_ outline, has been shaped apparently by the lathe—so accurate is the form—from a mass of opaque turquoise paste of frit-like nature.[14]
