As I can see on the picture.Maybe your mixture was too crunchy or your vibrating table might not be powerfull enough. Anyway, you should cook it to see what happen,

For ramming mass you need a pneumatic hammer or rather thin layers for ramming by hand, which may take to long for gunnables.
There are so many ways to make DIY mixtures which are less prone to glitches.

Rammed gunnable mite live to see itself as 1 of 4 cap blocks after all! Started the ramming a little late in the process, but man this stuff is tough... Some thinned down furnace cement to fill gaps? The recess is for the tee shaped S/S and ceramic wrap. It's a little squirrely, but I think it could be used. Any comments? Concerns? Thanks, Eric P.S. when I get the link for the pic from the Dropbox icon on the task bar, it won't insert. Do I use the "image insert" or something else? I ended up pasting the link by old technique. Help, PLZ?! Hi Eric, I was able to embed the pics from Dropbox by pasting the link into the insert image tool and replacing "www" with "dl". Like this- Original ......tps:// www.dropbox.co...... Modified .....tps:// dl.dropbox.co.....

Thanks Dave, Good to know! Does embedding still take up a lot of space here, or what? Still trying to catch up to speed on some computer stuff ... Just mixed another another bag of the Tough Shot, started a little sooner with 2 x 6 & lump hammer, had a friend handy with the shovel to transfer the mix. We'll see what comes of it. I will try your handy tip out tomorrow when I demold the thing. Eric

Embedding doesn't take up any space here, as the file is still located on Dropbox. It's just that high resolution pictures will take longer to load for people with slower internet connections. There are lots of free tools for reducing image size before uploading/embedding.
Looking forward to seeing the next castings!

Alright Y'all, need some Raku help! This is what my neighbor lent me to build a kiln... Anyone want to offer up a sketch utilizing this? I can take the burner out of the stand, I don't think it will mount up like yours Alex. I appreciate any help and suggestions Eric VW

Hi Eric! Just built a bell out of ceramic blanket and put the burner at the botom. Type propane ceramic kiln on youtube, there is a lot of inspiration out there. my kiln is a replica of the one in this video youtu.be/nRC_wunARes

On a side note... What to do with the clay slip-like clean out from the tile saw after cutting dense fire brick? Still haven't received a product data sheet from Cemex on their fire bricks they vend to the local Lowe's, so who knows what this clay slip actually is? That is, besides Karl ! Could it potentially be paired with sodium silicate for patchwork? Guess I could speri-ment! Here's what the goop looks like: Some slimy stuff, for sure! Hey Alex (and others), my 1/2" cf blanket is only 6# density- will that still work for the kiln, if doubled, tripled, quadrupled? Thanks y'all. Can't wait to put something other than questions and randomness on this thread! Eric

HI Eric,
You'll be able to discern more about the goo once it is dry. Maybe lay out a 1/2" patch of it on a pan over a heater. The extent to which it holds together once dry tells you of its clay content. The more it turns to powder the less useful it will be as a binder.

Caps in the homemade kiln- www.dropbox.com/s/jgfxqujjwcrqeg9/Loaded%20Kiln.JPG?dl=01" 6# ceramic blanket Burner scavenged from the turkey fryer There is a 2 1/2" vent hole where that wire is sitting on top Burned from 1 pm til 7pm, *NO* digital thermometer/ thermocouple, positioned the wood stove flue thermometer over the vent hole, pegged at 850 F in 1.5 seconds! Not very accurate, but at 8 am (13 hours later) the next morning the cap blocks were HOT to the touch (with 35 F temps overnight) when unloaded, soooo.... The one cap block with the noticeably darker face has been skimmed with furnace cement before firing, it was a little pock marked, but baked in quite nicely. So, what y'all say? Good, bad or indifferent comments accepted graciously! Thanks in advance, Eric VW

www.dropbox.com/s/m2q39y7sxsnijj9/post-firing%20kiln.jpg?dl=0This was the view when I first opened the door. Not sure what's up with the brown color, except that burner would change from blue to yellow/orange every few minutes- not ideal!I feel that the discoloration on the caps was a result of the burner acting up, too. AlexHarpin, what kind of thermocouples did you use- mineral fiber wrapped, or insert probe style? I've been looking up some digital therms and the thermocouples are nylon jacketed. I can get thermocouples separately, just not sure if they should be wire or hard probe type. Any input? Eric VW
