Reporting back, test 1 :) Have just made a 7" round blank. The tekta is on the bottom, capped with egyptian blue opal. Sifted the clear powder over the tekta before capping, and there isn't a single bubble visible. This is not the very best test, as this combination is probably less inclined to...

Hi Have fused a round small plate 1/8" tekta on the bottom, 1/8" egyptian blue on top, to full fuse. Beautiful, except for where there was a sort of 'scar' on the egyptian blue. This imperfect area has now left a distinctive trail of bubbles on an otherwise almost bubble free blank. Becaus...

I got it with the kiln a little over a year ago. It is not, however, a stand-alone controller; I just mentioned it because I find the non-scrolling type easier to program, and thought it was a point to be considered. Lynn, they make a 3 key controller and I think it is a 12 key controller, where yo...

My other kiln has a Bartlett controller, which also works well, but to program it you have to scroll through the numbers to get to the time and temperature you want (on the Rampmaster you just enter, say 300 dph or 9999 for full speed)...that's kind of annoying. Hmm, wonder if there are different m...

Hi Sandy I use this one from Bartlett http://www.bartinst.com/KILN/rtc1000.html . We built our kiln, had a Fuji controller first, then replaced it with the Bartlett. It is easy to use, keeps 6 user programs in memory with 8 segments each. You can add time to the current segment, or even change it, l...

Im' off to a bad start. I'm having trouble finding out what government department is involved in the safety processes and regulations. The Federal government refer me to the state government who then refer me to the electricity authority who refer me back to the Federal government! Less government ...

Hi Bob, Many thanks for all the details...had to smile about the NASA comparison :). Started by doing everything possible I could think of to cover all bases, now with the help of everyone that replied to this thread I am moving back to something that functions but is more practical...no point overd...

I would go SLIGHTLY heavier around the entire edge of a circle. If you can't see what is below the poeder, it's too heavy. You might want to do some tests to get the right amt of powder. I really use a very minimal amount. Many thanks Steve, I will surely test...very interested to see if I can mast...

I sift a minimal firly even layer of clear powder between the sheets. SLIGHTLY heavier on the corners. Hi Steve The "SLIGTHLY heavier on the corners" part, is this to keep the top plate minimally elevated at the corners to aid the elimination of air? Asking this in detail because all the ...

Thanks Valerie for this new (I mean new to me) idea.

Best regards, seachange.

Hi Stephen Thank you for replying. Sorry I haven't explained myself properly :oops:. Have changed the subject of the thread hoping to correct this. Basically what I am trying to do is to fuse two 1/8" layers together, or close equivalent in thickness, and minimize the bubbles. My tests showed a...

Hi, Have been making some tests with really slow fusings, long bubble squeezes and top firing, to try and minimize bubbles. Test pieces are small, square 4 1/4", round 9cm diameter (slightly less than 4"), this is in preparation for larger pieces. Tests 1 & 2: 2 layers of Tekta 1/8&quo...

Hi Jim

we used stainless steel 316, 2mm thick.

It has been there now for about 18 months. Have just started noticing the fine dust, but as mentioned above, it does not affect the glass at all.

Best regards, seachange

Thanks Arnold, had another query, have sent you a private email. it seems no one has a comparison test...had to try my luck :wink: . I imagine comparing would be difficult, considering all the variables in kiln use, plus those in kiln construction. In case it helps anyone, in our self built kiln we ...

Peter- check into the legal crap. Will you have to certify the kilns in Oz? Here in los estados unidos, UL listings can put a serious dent in start up costs. Business insurance must include product liability. Will you have to incorporate (ltd in AU?)? We were discussing this at the "datalogger...

Hi Peter, definitely seconding about all the legal stuff. We manufactured electronic equipment for 10 years. Getting started did cost a bit. Apart of having to pay for assorted test to get all the licenses, we also had to supply 3 complete, fully functioning units, so they could damage them in assor...

Hi, We need to fix the lid of an old Evenheat 2451 kiln. It has been used a lot, though with care, by previous owner, so usual story, grooves on lid have widened and elements are sagging. The bricks in the area where the handles in the front and the hinges in the back are located also need some fixi...

Hi Valerie, Many thanks for explaining your process, the sequence is more practical than what I was doing. Filling the strainer on the lid will keep everything better together. I'll see if I can get those japanese flat strainers here, the red ones are a bit small. Many thanks again Best wishes, seac...

Holy buckets! Last week I got my order for every color in 90 Coe. Great post, I am doing the exact thing you are. Besides all your questions , what's the best way to make samples? On cut glass? In a tile mold? Do you make the mold yourself? Thanks Seachange! ST You are very welcome, happy that my q...

You are probably overkill, I am underkill. I knock the powder off the spoon and move on to the new color. Single colors that have no way of being contaminated go back into the original container. Overspill from multiple colors goes in the trash. Dana W. Hi Dana I think some of my overspill will eve...
