Cutting Kiln Shelves

Recommended Posts

When I purchased a test kiln I thought the shelving kit that you could buy with it was on the pricey side.  So I bought a rectangular shelf and cut it up on our cheapo Harbor Freight tile saw and ended up with 5-6x6 tiles and a couple of half tiles.  The set I could buy had 4 shelves and was $60 and shelf I bought was $20, this was 15 years ago.  If you don't own a tile saw maybe someone who does will cut it for you or a tile store will for a small charge.    Denice

The classic "it depends" answer.

 

If the kiln shelves are silicon carbide, unless the tile saw has a diamond blade.......... nope... not really.  Masonry blades and SiC shelves are about the same hardness.  They wear each other out ;) .  Even then, silicon carbide takes its toll on diamond tipped blades too.  The large water cooled Harbor Freight BRICK saw with diamond tip blades will do the job on SiC.... but at a "price" in blades.

 

If the shelves are high alumina, or corderite..... yes.  They are like cutting brick (but with thinner cross section).  But it will 'chew up' anything except diamond tip blades, so if it is a lot of cutting, you might have to replace more standard "masonry" blades if that is what you are using.

 

best,

Thanks we own a tile saw w masonry blade. I saw some 1" shelves for sale. I doubt the person knows what they are made out, but either way, the masonary blade is a cost too if it wears out, so the savings might not be there.thank you

If there are any narrow strips left they are good to cut up for short kiln posts for when you just need to add a little height. 1" shelves seem so much heavier loading into and out of the kiln plus they slow the firing down, not sure if I would go for them unless you just have a small kiln. But then again if you have a small kiln then it's more wasted space having the thicker shelves. (unless you fire to cone 10)

Denice, Thanks,

After reading your post I went to my barn, prepared my Harbor Freight tile saw and cut two large half kiln shelves to sizes I can use.  The shelves were light yellow in color.  Took it slow and made sure the blade and shelf were drenched with water as I cut.
