Brass rubbing
Brasses
Most brasses can be rubbed without causing damage to the brass itself. The exception
is floor-

Incised slabs
Greater caution should be exercised when taking a copy of incised slabs. Only attempt to take a rubbing or dabbing when the entire surface of the slab is in sound condition. If the surrounding floor or wall is damp, the surface of the slab may be crumbling or flaking away or may be damaged by surface salts. In these conditions the lightest pressure of rubbing or dabbing can easily cause the worst affected parts of the surface to break away, causing irreparable damage to the slab. The only feasible method of making a satisfactory record of slabs with unstable surfaces without damaging them is photography.

To rub a brass you will need the following items:
Paper; a roll of strong but not thick paper, which will not yellow with age. The
best is all-
Wax 'Astral' heelball, available in sticks and hand-

The method outlined above makes 'negative rubbings' in which the surface of the brass
is coloured black, gold or whatever colour is chosen and the engraved lines are left
white. 'Positive rubbings', which in which the lines are black with the surface left
white, provide an excellent base for the application of decorative colour for heraldic
dress or shields of arms. To achieve this follow the procedure for negative rubbings
above. Then when you get home rub over the surface of the rubbing with a rag soaked
in waterproof black ink. It will colour the paper only on the un-
This is the best way of recording incised slabs and is particularly effective in recording alabaster slabs which retain coloured mastic in the lines. The details of the composition are best brought out with the help of a florescent light source positioned at a low angle so that the incised lines are shadowed.
Brasses can also be photographed, but great care must be taken to ensure that the
brass is evenly lit, ideally using photoflood sources. The use of a camera-

This is particularly effective for brasses which are worn or finely engraved.

Powdered graphite Available from art supplies shops.
Linseed oil Available from hardware stores. An alternative is a good quality salad oil.
Fixative spray Available from art supplies shops.

1. Prepare the dabbing medium by mixing oil and graphite to a stiff paste with a palette knife on one piece of cardboard.
2. Fix the paper as described in steps 1-
3. Dip the dabber into the paste Wipe off any surplus onto the second piece of cardboard.
4. Press the dabber onto the paper Avoid any rubbing movement as this will stretch the paper. Work systematically covering the whole brass and recharging the dabber with paste as necessary.
5. Fix the dabbing with the fixative spray to avoid smudges (optional).
