I have read the Clayart archives on shelves, and have a question:
Is there any way to remove all of the glaze drippings from a shelf
without using a grinder? I want to use hand tools only. Most of the
entries in the archive suggest grinders.
Thanks,

Yes, there are corrundum stones available at many pottery suppliers and at
your local hardware store - used for dressing mortar. Check your local
masonry supplier if the pottery chaps draw up blank or you can use a grinder
wheel or an old piece of silicon-carbide shelf. It'll take a bit of elbow
grease to get the glaze off, but it's nowhere near as frightening as using an
electric angle grinder - wear eye protection, just the same.
Good luck to you, now,

Yes, and I've not used it because its too hot! But this is something I
learned in the US service known as fire starter. You take your shelves out
to an area where there are no combustibles and a fair amount of sand.
let's say the desert, little to burn there. Take your shelf and add a fifty
fifty combination of red iron oxide, and powdered aluminum to the areas you
need cleaned. Have a shovel near buy. Now light the mixture,perferably with
a magnesium striker if you have one, and make sure your shelfs are at least
one inch thick and of high pressed alumina. When the mixture starts burning,
depending on the amout you've used, it will.....
a) burn at least to 3600 degrees f.
b) lossen those nasty stains on the shelf
c) burn straight through the shelf and or
d ) crack the shelf.
e) let the whole neighboor hood know you're a pyromaniac
Now comes the fun part, before the fire starter can burn itself through your
shelf you must shovel it and the glaze goop, off the shelf and into the
sand. Please do not use water as it will explode. If you're lucky you'll get
another try with the shovel on another shelf. But what the heck shovels, are
cheaper that shelfs!!!
Hey you've heard the saying "an ounce of pervention is worth a pound of cure"?
Good luck and have fun with this.

My only concern is safety. I'm thinking of people who don't follow
safety precautions.
I participated in a glass fusing workshop one time, and was amazed that
no one wore safety glasses. Little bits of glass from glass cutters
sailed through the air, but no one else seemed to notice. So I conclude
that most people lack safety awareness.

Arnold,
I have never had to spend much time doing this. BUT I have noticed a
pneumatic tool in my trusty Harbor Freight catalog (1-800-423-2567) for
removing rust. It has different attachments and uses a recprocrating
motion. It might work a little like the experts are telling you - but
perhaps get some of the lighter work done faster?? No idea if it will work
better. This Item# is 01109-4rbh and it is 49.99.
They also have a Air Hammer Kit Item#32420-7RBA price $38.99 (Ingerson Rand).
This thing has a 2 5/8" stroke and comes with a cutting chisel & punch. This
might be overkill?
Again, no idea, if these things will do what you need - or if somebody there
has to spend days doing this.
Best,
George Koller

Use a cold chisel and hammer - BUT ! make sure you have very very good eye
protection device, preferably full face protection. A hand grind stone or
chunk of silicon carbide shelf for smaller bits and clean up. p.s. do not
rub bare fingers over area to check it....very small broken glaze bits can
cut like a razor. Good work gloves should be part of your equipment. M.B.

When removing glaze from shelves with a hammer and chisel it is very
important to keep the chisel at a low angle to avoid breaking shelves.
M. R. W. on fri 30 jul 99
Arnold-the reason I ask about using a grinder was to
see if you were, perhaps, some sort of purist and had
some sort of "axe to grind" (pardon the pun) about
them. It seems that you don't. I always use a grinder
(and a chisel if necessary) and I would think that
you could find someplace around your area where you
could grind without bothering anyone. I can clean my
4 large shelves and 2 small ones in about 10 minutes
and have them ready for kiln wash. But, monkey around
with all that hand work with broken pieces of silicon
shelves, etc. if you want--not me!! --Reg

Hats off to Doug Adams and full Gonzo Pyro honors. There's a little pyro
in us all, neh?
An alternative method in the same vein requiring only simple hand tools for
those living in volcanically active areas, undertake at your own risk..
Don full fire suit inc. boots, hood & face shield and carry shelves to edge
of active lava flow. Carefully scoop small amount of fresh lava (av. temp
2200C) onto glaze drip, pause to dissolve drip and scrape off. Note: Avoid
areas of thin hardening rock skin over hot flows, ash clouds, exploding gas
pockets, new vents, lava fountains, and 'rock rain'.
I actually know a guy who used to scoop hot lava into moulds to produce
lava casts. Many close encounters with death. Pele was his favorite subject.
