The videos below will give you a brief demonstration on how to use gold leaf.
Gold leaf is usually sold in booklets, each leaf being separated by tissue paper.
It can be bought loose or pressed onto backing paper (transfer leaf) for easier handling.
Loose leaf is extremely delicate and tears easily. It also sticks to skin and cannot
be handled directly. You need to use a brush to pick it up.
You can also purchase gold powder, which can be mixed with Gum Arabic to produce
shell gold and can be painted onto the surface to be gilded. This method gives all
the lustre of gold without the hassle of handling the gold leaf.
Metal leaf is a more cost effective alternative to genuine gold and silver leaf.
It is thicker than genuine gold leaf and easier to handle. It is generally used for
furniture and framing but can make a good substitute in a calligraphy project, particularly
for the beginner.
A great deal of patience is required to work with gold leaf and it is important to
have the right tools and materials. For a calligraphy project on paper or parchment
you need to build up the surface to be gilded with gesso, which can be applied with
a brush or a pen. Gesso and other gilding materials can be bought from most good
art suppliers.
Scribblers.co.uk is a good place to start looking.
Once the gesso is dry, it is breathed on to give moisture and the gold applied to
the moist surface. With real gold you need to work quickly and with confidence as
the gold will stick readily and removing it is almost impossible. As it is very difficult
to cut the gold to shape and size you will always have some excess gold around your
gilded piece. This can be brushed away with a soft brush. Make sure you save the
pieces for future use.
If there are any gaps in the gold, you can breathe on the work again and stick some
of the scraps over the gap. Gold will stick to itself, so there is no further need
for gesso. The final stage of burnishing (or polishing) is done with an agate burnishing
tool (again, this is available from most good art suppliers). The burnishing will
flatten out the creased gold and give it the shine and lustre familiar to anyone
who has studied illuminated manuscripts.
