#78922 Olympic Kiln

Posted by neilestrick on 09 April 2015 - 10:25 AM

Would have bought an L&L based on my perceptions of better build and technology, but price difference was simply too high as I needed a glass kiln as well (Paragon Pearl 22). 

 

 

For future reference, glass can be fired in digital pottery kilns just fine. There is a myth among glass artists that you have to have elements in the kiln lid, or that you can't use shelves in the kiln. I have several customers who fire glass in their pottery kilns, including one who does large 22" wide slumped bowls and platters. She can fire 5 at a time in her L&L E28T-3.




#78775 Armature

The other issue is that the clay will shrink as it dries and fires. The armature will not shrink, causing the clay to crack.

It's the titanium. I've got a satin/matte titanium glaze that will do the same thing if it's on thick enough.




#77602 Firing In Mold

Posted by neilestrick on 18 March 2015 - 02:27 PM

Shrinkage could be an issue, as the mold will not shrink at the same rate as the clay unless it is made of the same clay. Thickness will also be an issue, since to withstand the pressure of dry pressing the mold would have to be very thick, and would probably not survive firing.

Did you just dry mix the 10,000 grams and pull out 100 gram tests of the dry mix, or were you working with wet mix?




#77421 Kiln Vent Operation

Posted by neilestrick on 15 March 2015 - 04:28 PM

A vent will not even out a firing unless it's only very slightly uneven. The only way to ensure even firings is to modify the load as I described above (which still may not do the job), or to get a kiln with zone control. More thermocouples = even firings. Most brands offer zone control as an upgrade (Skutt, Paragon, etc.), L&L has it as a standard feature. It's well worth the money to have it.




#77074 The Max Wheel 1500?

Alpine made a gear drive wheel. There are still some in use.




#77071 The Max Wheel 1500?

Posted by neilestrick on 10 March 2015 - 02:55 PM

We had one of these in grad school. Tons of power, but had a very different feel than all the other wheels because it was gear driven, no belt. It'll be great once you get it running. If you know what's wrong with it, I'd just Google search by the part numbers on the parts you need. Chances are it was built from off-the-shelf parts.




#76940 Underglazes Vs Glazes

Posted by neilestrick on 07 March 2015 - 12:33 PM

Commercial underglazes fuse more than a slip would. That's why they can be used on bone dry clay and bisque ware without flaking off. They can be fired in bisque and still be porous enough to take glaze. But they don't go into melt like a glaze. They are quite versatile. Most home made underglazes are either more of a colored slip that has to be applied to leather hard pots, or are just stains with a frit binder and work best on bisque. I was working on a new commercial underglaze formula when I left my last tech job, and I can tell you that they are fairly complex. It's a fine balance to get them to fuse to leather hard, bone dry or bisque, but still be porous enough to take glaze after bisque firing, to play nicely with glazes, and to brush well.

Just buy a kiln shelf.




#76764 Are You Taking Pictures/notes While Working?

Posted by neilestrick on 04 March 2015 - 03:59 PM

Hi Neil, maybe I should join Instagram or another social media to force myself to take pictures...

 

Yes, it's a great way to force you to do it, plus it's great free advertising, too. I've got 600 followers in IG and I don't know most of them. I like it much better than Facebook because there's no drama or games or all that other stuff that makes Facebook so annoying.




#76762 Are You Taking Pictures/notes While Working?

Posted by neilestrick on 04 March 2015 - 03:26 PM

I try to to take a picture every day of what I'm working on so I can post it to Instagram. I keep them all on file to use on my web site and Facebook, too.




#76398 What Causes Glaze/clay 'tide Mark'?

Posted by neilestrick on 28 February 2015 - 09:38 AM

It's solubles seeping out at the edge and/or fuming. Lots of glazes do this, it's not necessarily tied to the barium. I would point to the neph sye as the culprit rather than the barium.

#75802 Here Is What I Ordered - Never Mixed My Own Glaze Yet

Posted by neilestrick on 19 February 2015 - 09:45 PM

Really?! Oh man, that crap from Seattle Pottery clumped as bad...OH WAIT, HAAAA
BENTONITE
THAT'S what I mean! Bleeding BENTONITE
These names are too much for my wee rodent brain, anymore... >.>

 

You won't need to mix it in the blender if you dry mix it well with the other glaze ingredients before adding it to the water.
