Re: HOMEMADE IRIDIZING?

I have some but was waiting for warm weather so I could push a kiln outdoors. IDK, seems it isn;t hideously dangerous to your health, in the small amounts being used, other than the lung irritation. https://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+582 But why take chances. :shock:

Re: More Kiln Adventures

Update on this, the TAP tech rep says that the resting temp displayed is actually the temp of (or around) the controller circuit board. Which is fine I suppose, but explains the delta. I've used the controller for several months now and really like it. I think that rep may have snowed you. If your ...

Re: Hairline 'crack'

Finger crossed for you Bonnie, gee that stinks. Sending you healing vibes. I had one a few weeks ago that was 3 layers of 3 mm and the bottom layer cracked and separated about 3/16-1/4". I'll be if it didn't fill itself, heal and level in one darn fuse(1470-1480). And all was good. Break a leg!...

Re: HOMEMADE IRIDIZING?

My wife does a lot of mica design work and uses clear ink(they sell this for use with stamp pads). Seems to really stick the mica tight to the surface. Different brands really work out differently. We don't like Fusemaster, seems to have some kind of additive than can boil if at all too thick and ge...

Re: Ball milling residue

I realize this thread is as old as sin. My theory is you are picking up pieces of your poly drum. I've tried grinding frit in many things - if there is ANY exposed rubber or plastic, even just the sliver of a gasket on a glass blender,etc., you are going to have that grey clouding. Crushing with ste...

Re: Carving vermiculite

Mike, I use what are known as "ribbon tools" for carving vermiculite board and I also use them a lot on clay. On clay they are nice as they remove clay, not just push it from one place to another like solid tools would do. Like these. 30372-1006-1-2ww-m.jpg You can use any router bits that...

Re: Loose abrasives vs. bonded(pads,etc.)

Thanks Marty. I was really probing more for whether people are moving away from loose abrasives for cold work as bonded abrasives become cheaper. I generally only use loose abrasives below 1000 grit if I am trying to get a matte finish - I don't consider them a good use of time if I am trying to get...

Re: More Kiln Adventures

Look in your instructions - there is probably a thermocouple offset, specifically to change this niggling little issue. I personally like the cold kiln to show room temp within a few degrees of reality. I actually expect them to read a hair lower than air temp, since they are sitting on a concrete f...

Re: Polishing any fused glass in a rock tumbler

Not to be a buzz kill, but you just publicly revealed your proprietary idea. Not seeing how this is different than what many people already do, using rock tumblers or vibratory laps(me). Tumbling is really slow way to get a final polish - hundreds of those chips could be laid on a kiln shelf after t...

After trying to clean it, maybe try a little cerium oxide with a wet cloth. To polish the surface. Hopefully it is not ruined. :cry:

Re: Slumping issues

Did a little more investigation on the glass. As long as my wife doesn't read this, I'm good. Otherwise :evil: Since this was one of her projects and not mine, she said there was not a number on the glass. Come to find out the 96 did have a number (OA/3005-95F Opal Art) Have been telling her to kee...

Re: Slumping issues

The bottom picture shows it somewhat, but the bowl is out of round by a good 3/8". I am assuming that the glass shifted while it was firing. I have since read on this site (suggested by Brock) that it helps to put a small bevel on the glass that is in contact with the mold to prevent slippage....

Re: Slumping issues

I figure that at 1100, the glass is just about ready to move. A hold at that point ensures the glass is evenly heated throughout and a slow transition up to my final temp allows the center of the glass to soften and fall, as it is unsupported, before the edges get hot enough to soften and slip caus...

Re: How to polish a tiny spot

220 seems fairly aggressive (to me :) ). 800 grit burrs are easy to find. Diamond powder with a little carrier(oil) using the wood stick in drill(dremel) chuck is good for small round spots. https://lascodiamond.com/LascoProducts-DiamondPowder.html A gram of diamond dust is about 1/2 a thimble full....

Loose abrasives vs. bonded(pads,etc.)

My primary experience in glass polishing came from polishing watch crystals (watchsmith for almost 2 decades.) Anyways, in watch world people rarely use loose abrasives, on thought that errant granules are more likely to create scratches as deep or DEEPER than the size of the grit and will deepen lo...

Re: Sharing studio space with friend or significant other? Horror or heaven?

In college, the pottery studio was a collective and I really enjoyed that. We seemed to feed off of each other's creativity.
