Biglou13 Posted July 20, 2014 Report Share Posted July 20, 2014 What tools do you use ? Links would be great. Pics and or,video would be great also. Was thinking about diamond pads from toolcity.? Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 21, 2014 Report Share Posted July 21, 2014 For small things I use a dremel with a grinding wheel. For larger I use a Makita 4" angle grinner with a grinding wheel. Put the shelves on a bag of clay to absorb shock. I use a chisel with knuckle protector for small drips. Marcia Link to comment Share on other sites More sharing options...
Benzine Posted July 21, 2014 Report Share Posted July 21, 2014 If you are referring to cleaning, as in getting rid of old kiln wash and glaze, this is what I use: https://www.continentalclay.com/detail.php?PID=542&cat_id=193&sub_categoryID=61 For the really large drips, they usually just come right off by hand, due to my excellent kiln washing..., and if not, I use a flat heat screw driver to pop them off.

bciskepottery Posted July 21, 2014 Report Share Posted July 21, 2014 Would you like eggs and toast with your links? Would not recommend the diamond pads . . . you'll eat through a ton of them. We just cleaned 21 shelves from a salt firing . . . used carbide grinding stones, stiff putty knives, chisel with hand protector; so serious glaze runs so the angle grinder stayed at the workbench. For small glaze drops, a flat-headed screwdriver and hammer work. You just need to learn how to angle the knife/screwdriver/chisel so that you catch under the lip of the glaze bead. For bad glaze runs, grinder. And, in all situations . . . wear your respirator, eye protection, and work gloves (no cheap cloth gloves); slivers of glaze can cause serious cuts. And never run your bare hand over the kiln shelf to see if there are any glaze spots that need removal. Link to comment Share on other sites More sharing options...
Biglou13 Posted July 21, 2014 Author Report Share Posted July 21, 2014 Which grinding wheel? Link to comment Share on other sites More sharing options...
Guest JBaymore Posted July 21, 2014 Report Share Posted July 21, 2014 I use diamond on an angle grinder on silicon carbide and Advancers. When they need a big going over.... take them to the sandblaster and say "me em' black again. Simple. No hazard. best, ..................john Link to comment Share on other sites More sharing options...

Biglou13 Posted July 21, 2014 Author Report Share Posted July 21, 2014 Well the group studio I'm at has some, poorly old kiln was shelves For the ones old crusty flaking kiln wash, Is it necessary to grind it all off , to the shelf. Or just smooth? Some shelves are chipped, is there a need to try and fill these chips? Yes mark saw that post. No bacon with breakfast? For,non diamond grinding is this what you all are using? http://t.harborfreight.com/4-inch-diamond-turbo-cup-wheel-98772.html?utm_referrer=https%3A%2F%2Fwww.google.com%2F There is this one shelf out back that has a whole cup,still attached, it looks like it's been there for years. I really want to get that off without killing the shelf. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 21, 2014 Report Share Posted July 21, 2014 I got a pack of three diamond grinding wheels off ebay a few years ago. Still on the first one. It was a great price. Marcia Link to comment Share on other sites More sharing options...

I really want to get that off without killing the shelf. Hahahahaha!.... You should take a picture of that, and post it in the studio with the caption, "Don't Forget to Claim Your Work". I approach applying kiln wash, the same way I approach painting the exterior woodwork on my house; scrap any of the loose bits off, anything that doesn't come off with a thorough scrapping, won't cause any issues. You don't need to fill in the chips, just coat them, as you do with the rest of the shelves. Link to comment Share on other sites More sharing options...

I thought advancer and silica carbide didn't gunk up with glaze. Are you grinding from ash firing? Yes....... I fire a noborigama. Regular silicon carbide does "gunk up". And for the Advancers....... most of the time I just use a putty knife to flick off stuff.....not much stuicks (but for about $250 a shelf... they should even stack themselves). My point was that I am not using diamond on clay ar alumina shelves.... hard to not eat a hole in thiose instantly. But sometimes the kiln wash builds up and gets uneven more than I like. And I DON'T like getting exposed to repeatedly fired stuff that contains microcrystalline silica in the cristobalite form (fired kiln wash)... hence the sandblaster comment. repeatedly fired kiln was dust.... BAD stuff. best, .......................john Link to comment Share on other sites More sharing options...
Mark C. Posted July 21, 2014 Report Share Posted July 21, 2014 I use two tools From graiger a silicon grinding CUP it large and does heavy duty work on a 9 or 7 inch milwakee grinder threaded shaft this is for silicon and dry pressed high alumina shelves 98% of the time I use a makita 4 inch grinder with masonary wheels from harbor frieght sold in 10 packs-I also us a diamond wheel like the one you show but it will eat shelve fast so I am very carfull; with it This small 4 inch grinder tool is easy to hold I have one hanging next to car kiln My advancer shelves rarely need any grinding I mostly grins my salt shelves but even those need little as dry pressed high alumina does not attract salt.

Benzine Posted July 21, 2014 Report Share Posted July 21, 2014 best, .......................john They don't?!!! I figured it was like something out of Harry Potter; flick your wrist, and the shelves float into the kiln to load, and once done firing, another flick of the wrist and they put themselves away. Pffff, so much for the "Advance" portion of the name... Link to comment Share on other sites More sharing options...
schmism Posted July 21, 2014 Report Share Posted July 21, 2014 4" diamond cup wheel (suitable for standard 4.5" hand held grinder) http://www.homedepot.com/p/RIDGID-4-in-Double-Row-Diamond-Cup-Wheel-HD-AWD40/202884364 or just the standard 4" diamond cuttoff wheel for the grinder. This one will leave u shaped divots if you are to aggressive with it http://www.homedepot.com/p/QEP-4-in-Premium-Diamond-Blade-for-Wet-or-Dry-Cutting-Porcelain-and-Ceramic-Tile-6-4003Q/100140124 they also make small 1" versions for your dremel if you need to blend drips off the bottom of your glazed pots/bowls etc. Link to comment Share on other sites More sharing options...
Mark C. Posted July 21, 2014 Report Share Posted July 21, 2014 Lou I do have some video of grizzley bears eating salmon from our Alaska trip last week if this helps. Its a bit off topic but heck most threads drift far from the nest anyway. Mark Link to comment Share on other sites More sharing options...
Biglou13 Posted July 22, 2014 Author Report Share Posted July 22, 2014 I'd love to see that. Not to mention that some here uses fish in his designs. And the outdoors are great for creative inspiration And some fresh salmon would be amazing right now, smoked salmon!, gravlax, salmon sushi, sashimi, ........lucky bears!!! There is prolly some granite content in rocks, which means there prolly is some feldspar in video also. not to mention silica, It's video source of glaze material.

Biglou13 Posted July 30, 2014 Author Report Share Posted July 30, 2014 1st grinding session done! Bought this. http://t.harborfreight.com/4-inch-angle-grinder-91222.html And this http://www.toolocity.com/index.aspx/ImageGallery/Index?productId=2003 The old wash and drips big and small came off like butter Less than 2 minutes per shelf, I did eat through 100 grit pad, maybe a bit overkill I may try a different pad next time, or maybe lower grit. And or the stone that came with grinder. It took longer for me to set up and break down than grinding 5 22" shelves It wasn't the chore everyone groans about.

Guest JBaymore Posted July 30, 2014 Report Share Posted July 30, 2014 It wasn't the chore everyone groans about. Try 60-80 shelves at a time between woodfirings. best, ...............john Link to comment Share on other sites More sharing options...
Biglou13 Posted July 30, 2014 Author Report Share Posted July 30, 2014 Do you grind between every firing? Do you kiln wash for woodfiring? 60-80 (Isn't that why you have students) I'd invest in a sandblaster Maybe I'll just continue to pay to have my work fired. Nah I still want my own....

Guest JBaymore Posted July 30, 2014 Report Share Posted July 30, 2014 This is for my personal kiln....... no students. Yeah.... generallly at least touch up shelves between every firing. Every so often.... send em' out for blasting. Woodfiring is for masochists. The collge's anagama is bring built in August. Then the students can learn the fun of "be careful what you wish for". best, ...............john Link to comment Share on other sites More sharing options...

This is despite the fact, that I've seen your whole right up, on everything that goes into it... By the by, how big is the interior space of the anagama kiln?

Guest JBaymore Posted July 31, 2014 Report Share Posted July 31, 2014 Benzine, It is deliberately a relatively small anagama. One of the design constraints. We want to be able to fire frequently within the context of the overall academic program's needs, and with not too large a crew needed for each firing. It is almost exaclty 200 cubic feet. best, ...............john Link to comment Share on other sites More sharing options...
Biglou13 Posted July 31, 2014 Author Report Share Posted July 31, 2014 That sounds tiny. I visualized 10 foot by 5 x 4. I'm jealous nonetheless. Link to comment Share on other sites More sharing options...

It's one reason my Raku kiln is small and portable, because I take it to school, so I can use it with my students. How tall is the anagama you are about to build? And I guess I should ask, how big is a "typical" anagama? Link to comment Share on other sites More sharing options...
