Transform daily objects into veritable
works of art.

Water based porcelain and ceramic
paints have revolutionised the art of
porcelain painting. Thanks to them
everybody can have a go at this
wonderful technique, turning glass,
ceramic, porcelain objects into a real
work of art. All paints are fixed by
simple cooking in a conventional oven
no kiln is needed! The illustrations
in this article show some of the
possible results. The water based
colours are thermo-hardening and
specifically designed to adhere to
surfaces such as porcelain,
terracotta, metal, glass, and ceramic.
Their ease of use and flexibility
(soluble in water and re-dissolvable
when dry) make for a perfect medium
for schools and decorative arts
enthusiasts. After baking, the colours
offer an amazing finish � resembling
that of a glaze, and they are
waterproof and dishwasher safe!

These colours are suitable for all
supports that are thermo-stable up to
about 180C. Dependant on the
absorption of your support you can
play with the colour in numerous ways
multiple coats, washes when diluted
with water, and even thicker coats to
give more impact to the finished
project. For multiple coats allow the
previous to dry for at least 20
minutes, and for wash effects if you
use too much water the paint may lose
its adherence � although most
manufacturers sell mediums to correct
this.
All objects to be painted should be
clean, dry, and grease free before
work starts to do this use
turpentine, white or methylated spirit
and a lint free rag.
If you want to make corrections before
baking this can be done with a paint
brush and some water or alcohol.
All work should be left 24hrs before
baking, as with most paints thicker
coats may well need longer than this.
Firing temperatures vary from
manufacturer to manufacturer see
product labels for details.
After drying for about 24hrs in the
open air, place your object in a cold
oven, and set the temperature given on
the packet. After the oven reaches the
temperature given leave it about 35
minutes. After this time switch off
the oven but leave the object inside
whilst the oven cools down. For large
objects the firing time can be
extended by up to 10 minutes.
Firing times and temperatures are the
determining factors to the finish of
the article, colours won’t glaze
properly if the firing time is too
short or not hot enough. However on
the other hand over do the firing and
the colours will brown as they burn.
A cooking smell is quite normal during
firing
