The décors in the style of naturalistic floral painting have established the company's artistic reputation. They are freely painted by hand, and are always unique specimens. Only the theme and arrangement of the motif is defined; each painter individually determines its configuration. Since 1832, hand-painted items have been designated by means of an exclusive painter's mark, the orb.

Gilding is done with 24-carat burnish gold, consisting of finely powdered genuine gold, which is then polished either to a mirror finish millimetre-by-millimetre using an agate burnisher – and also often skilfully engraved with elaborate décors – or to a matt lustre with sea sand or a fibreglass brush.

The final firing for on-glaze painting (at around 860° C) is called muffle firing. A separate compartment in the furnace protects the individual pieces against the effects of smoke and flames.

An additional distinction for the on-glaze colour has been applied to painted porcelain since 1803.  The painter's emblem has also undergone changes throughout time. Today, the stamp is in the shape of an orb. In most cases, it is placed next to the sceptre. The orb is applied in various colours depending on the type of decoration. A red orb indicates all décors with floral painting and coloured figures and landscapes. A green orb is used for all decorative work (gold, platinum, coloured décors, monogrammes and coats of arms) not involving flowers. A blue orb is stamped on all décors that are executed with quick-fire colours. These colours are fired at very high temperatures and fade into the melting glaze. After firing, they are protected in the glaze coat but are not noticeably raised, as the on-glaze colours are. They are dishwasher-safe. A black orb indicates a printed décor. A lithograph based on a drawing is produced as a template for the ceramic screen printing. The motif can then be produced in the desired scale with porcelain paints, even with HTS paints on request. If, for example, company logos are desired in substantial numbers (100 or more), they can also be produced using a printing method. The price depends on the number of colours and the number of copies.

In addition to the orb emblem for decorated porcelain, there are also small, hand-printed emblems on the bottom of the porcelain. Each porcelain painter has a personal emblem, which is used to sign the porcelain that he or she decorates. Every hand-painted piece of porcelain is a unique specimen, marked with the "signature" of the individual painter.
