Glaze Group Meeting
10th April 2007
This meeting was arranged so that we could discuss and demonstrate our
individual glazing techniques which took place in Diana's garage where
Mike had set up a table.
Brush on glazes: Mike and Rose gave practical
demonstrations of the techniques they use.
Mike added to an existing glaze slop, dry wallpaper paste (cheap
equivalent to proprietary Courgel) in the proportion of 2% weight to an
estimated 100gm of the dry glaze, adding no extra water. This was
then whisked with a kitchen mixer to an even consistency and should
normally be left to stand.
Using a soft brush, Mike applied the glaze generously to cover several
pots, about 6 thin coats being needed to build up the required
thickness, with time to dry between coats. Mike explained that
although a slow process compared to dipping, brush on glazes have the
advantage of requiring very little glaze which adheres well and does not
powder on handling.
Rose demonstrated her procedure with a brush on crystalline glaze on a
vase. She said that because the glaze tends to run and pool, less
glaze should be applied to the body compared to the rim. Using
gentle brush strokes with a smallish brush she therefore applied 6 coats
to the rim and only 3 lower down, allowing time to dry between coats.
Results of these glaze tests will be brought to the next meeting.
Dipping techniques: Charles demonstrated his procedures
using our standard artificial wood ash glaze. To ensure the
critical thickness needed to achieve chun effects he controls density of
the glaze slop with a hydrometer; controlling slop weight to about
1600gm per litre; and by dipping a bisqued sherd into the glaze.
Charles demonstrated two techniques for glazing bowls; in both bowl was
upturned and dipped immediately into the glaze bucket. This was
not too easy as the bowl had no foot. Supporting the second bowl
with a hand inside (a cloth preventing it from slipping), the glaze was
poured continuously all round the outside. Charles prefers this
last method to supporting bowls on 2 slats.
It was agreed that this meeting had been most successful and informative
and it is proposed to hold other demonstrations in the future.
The next Glaze Group Meeting will be at Diana Carter's home: "Dellcroft",
Hensting Lane, Owlesbury, Nr Winchester at 12 noon on Tuesday 10th July 2007.
Everyone is welcome. A contribution towards a light lunch
will be appreciated. Let Diana Carter (01962 777297)
know if you plan to attend.
