3. Introduction to Glazing
• Glazing is when you paint a thin layer
of minerals and glass onto a fired or
unfired ceramic piece
• Glaze can serve to color, decorate or
waterproof an item.
• Glazes may also enhance the
underlying design or texture

4. Glaze vs Underglaze:
• Underglaze: can be put all over
the ceramic piece (inside,
outside & bottom)
• Glaze: liquid glass that can be put
everywhere except the bottom;
also makes piece food safe

5. History
• Glazes have been discovered to
have been used in the decoration of
ceramics as far back as the early
Egyptian period.
• Powdered glass was originally used
as the base of historic glazes.
•
• Minerals and water-soluble salts
were added which altered the color
and texture of the final product.

6. Major elements in glaze
• Glazes need a balance of the 3 main
ingredients: Silica, Alumina and Flux.
• Too much flux causes a glaze to run,
excessive flux oxides may form
visible, possibly lumpy, crystals.

• Too much alumina causes a glaze to
stiffen and tend towards opacity

time-consuming way to glaze

9. Second firing
• Bisque firing is fired to
between 980 and 1,100°C
(1,800–2,000°F).
• Once glaze is painted on the
piece will go back into the kiln
to change the glaze to its final
look
• In manual firing temperature is
measured according to the
cone.
