My wife likes to file on her paperclay sculptures when they're bisqued.
This of course wears out wood rasps really quickly. Does anyone have
any suggestions for files or rasps that would be more appropriate?
She really like the look produced by filing them when they're bisqued,
so she's not interested in suggestions for any kind of finishing of wet
clay or greenware, and she's not interested in sanding. She wants file
texture.
Thanks,

Hi Paul, i also make wood bowls,at i used to make them. I havent had time. I
actually did it at work in the fire station. I would put on a Scott pack and
grind away.
Any way, i used a 4" grinder with a chainsaw blade.I kind of scared me so i
bought some other grinding wheels that fit my 4" grinder that were safer.
I bought them through a Wood workers catalog.They mite fit the bill,worth a
try.
They came in different grades. Although i loved my little 10,000 RPM chain
saw.

Hi Paul,
Have you tried rasping the DRY greenware and then Bisque firing? I've
always liked chissel marks. Try rasps and chissels for marble and stone
workers.Mike Gordon

Hi, Paul.
Have you checked at you hardware store? (A small, owner-operated one--not a
warehouse where no one knows anything) I'll bet you can buy files, etc.
designed for masonry.

I make a lot of large sculpture in a small kiln, i.e.
multi-part work. Often, parts cannot be fitted while green
for structural reasons, so I bisque, and then grind to fit
with an angle grinder. It chews right through bisque, and
I have discovered that I can do a fair amount of direct
carving with the grinder. (Use the masonry discs.) There
are also 'stone' grinder bits that fit your drill, for
detail work. The amount of 'grinder marks' remaining when
finished is up to you.

stone sculptors use rasps and files - not sure if they're different or where
to get hold of them - all the sculptors I know (not a large number, come to
think of it) use old wood rasps.
Maybe that's the answer - go around a dozen garage sales, or whatever passes
for car boot hell where you are, and buy the ones that other folk are about
to through away - then treat as disposable. Who knows, someone might find a
use for them after you?
I'm assuming here that you are using a file cloth to clean the cutting
surface? It won't last long on clay, but it will helps.
Otherwise, what sort of surface would you get from a carborundum stone, or
similar?
Funnily enough, when I cleared out my father's shed last year, I kept some
old files for working soft stone - they are currently sealed in a box with
enough chemicals to kill off the woodworm in the handles, I hope...

Dear Paul
A farrier's Rasp . They have to have them very sharp and are forever
replacing them . They always have a few months wear in them I use mine for
wood.
I also have the belts from small belt sanders with a bit of wood cut to
size in side them - my most used tools
-- Regards Paul Talyor.

This is a case of resending, using the excuse of server crash. I apologize
to all who got this previously, it is no different - there was no way to
improve it (G).

Is this where scully and muldar find the mutating tea pot/cream
pitcher/pickle crock behind the kiln, just waiting to strike?

She wants file texture.“
I am engaging in some hyperbole in saying that all ceramics are harder than
all metals. While not entirely true, it is true enough to indicate that
wearing out metal files on bisque will be a fact of life, regardless of the
file chosen. That would indicate that the best choice is the cheapest file.
If the shape of the tooth marks on the material are the desired effect then
there is probably no alternative. If that is less of an issue, several tool
companies sell diamond files, metal shapes covered with diamonds of various
sizes. The diamond files will last MUCH longer.
A second alternative might be to make a ceramic file with teeth like she
likes. A high fired toothed bar might serve for her shaping and be an even
cheaper choice. An lovingly made by her husband, to boot.

manganese is refractory, how could it also tend to fuse things? perhaps this
is another case -like iron- of different behavior at different
temperatures?”
This is a little like asking, “Why is there air?” If the detailed answers
to this kind of question, predicting the behavior of oxides in a molten
mixture on some theoretical basis, are available, I am not sure I want to
know. Having faced chemical thermodynamics and Gibbs Free energy of
crystals in times past, I believe I am satisfied here with rules of thumb,
words of wisdom, and the necessary but oft despised glaze testing.
