Tip #55:
Specialty Glazes; Surforms, Glazing Tips
Today's newsletter contains a variety of tips. First I will point out
some of the exciting glazes that are available, in case you want to try
something new. Next are some tips on using a Surform, and finally some
glazing tips.
Exciting Glazes
Many people are not aware how many different specialty glazes have been
created in the past few years. I would like to point out a few of my
favorites.
Low Fire:
Want to simulate stoneware glazes in low fire? The Spectrum Low Stone
and Amaco Stone Texture Glazes do just that. The Amaco Stone Texture
glaze series flows a little in the firing, settling in the crevices and
towards the bottom of a vertical surface. Therefore, when applied over a
textured surface they will produce antique-like variations or a
weathered and worn out look on the higher relief areas of the piece.
Prefer the look of granite? Try Duncan River Rock (shiny), or
Stonewashed (Matt finish)
Crystals and Crackles are sure to dazzle. These glazes are one color,
with small chips of other colors imbedded. Spread the small chips over
your glaze, and you will get dazzling results. Duncan Crystaltone,
Duncan Crystals, and Amaco Crystaltex all provide these results. Or, you
can buy glaze crystals and add them to any color glaze.
Other favorites are Amaco Alligator which are variegated, Duncan Art and
Courtyard Art which give different but interesting effects in each
firing, and also a variety of crackle glazes.
Mid-Fire: Cone 5/6
The Amaco Sahara High Fire and Spectrum Stoneware lines of glazes
contains a number of colors designated as "textured". These
give variegated results, often a different color where thicker, or
alternating glossy and matt areas. HF41 is a popular green that is
darker where thicker, such as in carvings or at the bottom of a bowl.
Other transparent glazes will give the same effect.
Laguna has added a new batch of colors which are satin finish, rather
than a high gloss. These are MS125-MS134. They also have introduced a
new line called "Mystic" glaxes. These radical glazes redefine
'break-up" at Cone 5. The mottled and shimmering colors create an
exciting, almost "dancing effect" whether on functional or art
ware. These are WC100-WC114. All the Laguna glazes come in pints and dry
form.

Surform
If you work in clay, I guarantee that once you try a Surform you will
never give it up! I recently saw a whole 2 day workshop was being taught
on using a surform.
Similar to a rasp, and Surform has many uses from texturing clay to
forming and trimming. For example, if you try hand trimming slabs, or
rounding off the sharp edges on the bottoms of pots, it is easy to
accidentally cut too deep. In seconds you can ruin a piece. But with the
Surform, you just lightly shave off a little at a time, until your piece
has the perfect shape and size. If I had to keep only 6 tools, the
Surform would be one of those.

Glazing Tips
Square containers: Many people mix glazes in 3.5 or 5 gallon buckets.
But really, the shape is not great. How many times have you tried to
glaze a piece that wouldn't fit inside the bucket? A much better idea is
the rectangular plastic/rubber containers you buy at Target, Walmart, or
any home improvement store. You can glaze larger pieces, and you have a
wider opening to work in.
Pouring Glaze: You can also place sticks across your rectangular tubs,
place your piece on the sticks, and pour glaze over the piece. This can
be done with a bucket also of course, but works much better with the
wider openings of the rectangular tubs. I often use a ladle to do the
pouring, or a mug I don't like much!
(The only disadvantage I can see is that the Talisman sieves fit nicely
over a 5 gallon bucket. So it is useful to use a bucket when sieving,
then transfer the glaze to a tub.)
Fluorescent Light Grates: And something that works even better than
sitting your piece on sticks is to go to the hardware store and buy the
fluorescent light covers that look like grates (a grid of 1"
squares.) These easily support your piece (it won't get bumped off the
sticks), and still has plenty of holes for the glaze to run through.
Dipping Drips: I have found when dipping that you can get an irritating
drip at the end, no matter how long you wait and try to shake off the
piece. To solve this, simply blot that last glop of glaze lightly with a
damp sponge before it dries.
Glazing on the Wheel: And here's another glazing tip I was grateful to
learn! Center your piece on the potters wheel. Fill a squeeze container
with glaze. This could be a bulb syringe (used for cleaning wax out of
ears), or a plastic squeeze bottle such as catsup or mustard comes in.
With a wide brush in one hand (wet first with glaze), and the squeeze
bottle in the other hand, turn the wheel on low speed. Put your brush on
the piece, and squeeze from the bottle onto (or just in front of) the
bristles as you go. This keeps the brush full of glaze, and you don't
have brush marks from stopping, reloading the brush, and starting again.
Move the brush down the pot, back up again, etc, until you have the
desired glaze thickness. Voila! It is fast too!
Hope you enjoyed our tips!
