CONTINENTAL PORCELAIN
Porcelain has this distinguishing characteristic, that when held up to a strong light it appears translucent, unlike fayence, which is perfectly opaque. Its fracture is hard and white internally, like a broken piece of alabaster.
Porcelain of soft paste has the appearance of an unctuous white enamel like cream; it is also to the touch of a soft, warm, and soapy nature, something like the surface of fine fayence. The pâte tendre is also soft in another sense, being unable to bear so great a degree of heat in the furnace as hard porcelain. The soft paste may, therefore, be easily cut or scratched with a steel point or a file, which would have no effect upon the hard paste; it is consequently liable to become much scratched by frequent use. The hard paste or true porcelain is of the whiteness of milk; it feels to the touch of a hard and cold nature, and is somewhat heavier than the soft; underneath the plates and other pieces the rim or edge is left unpolished, or without glaze.
The painting upon porcelain is executed after the ware has been baked. Whilst in a biscuit state, the piece to be painted is dipped into a diluted glaze; it readily absorbs the water, leaving on the surface a thin coating of components which quickly dries into a solid shell, uniformly thick over all its parts, and sufficiently firm to bear handling without being rubbed off during removal into the seggar or case which protects it in the kiln.
The amateur must be upon his guard in collecting porcelain, and not place too much reliance on the marks which he may find upon the ware. When the mark is not indented on the paste, or baked with the porcelain when at its greatest heat (au grand feu), it gives no guarantee of its genuineness. The mark was nearly always affixed before glazing. It is necessary in forming a correct judgment of the authenticity of a piece of valuable china, such as Sèvres, that many things be taken into consideration: First, above all it is most important to be satisfied whether the porcelain be of hard or soft paste, and whether such description of paste was made at the particular epoch represented by the mark; then, if the decoration be in keeping with the style adopted at the time indicated, the colours, the finish, and various other indicia must also be taken into consideration.
