Many have put it to me that glass "wants" to be 6mm or 1/4 inch thick. The scientific explaination is not that it "wants" to be but the surface tension of the material when it is in a liquid form forces it to be this thickness. This surface tension is a function of many things, m...

The following link is points out exactly what I've been talking about. http://money.cnn.com/2003/07/02/news/companies/telemarketers/ They mention the "big guys" like AT&T and insurance companies but these companies get their mailing lists from multiple sources. They will buy them from ...

Sara,

That is the best solution I've seen posted yet. My beef is that consumers need to be given a choice. As an artist, a commercial one at that, I see the need to support my customer base to help continue sales. Your method strikes a great balance for both.

Dotster.com is reliable and affordable.

I agree with Charlie and the point I made before. It is one thing to receive email from a friend. I have a friend for a case in point that "Spam's me" just about every other day with about 6 or 7 email jokes. It's a sensitive issue as they are a good friend and for the moment, it's not a r...

Check out the grinders at Kingsley-North http://www.kingsleynorth.com/grindingunits.html This is the type of unit you are looking for. They have multiple grit wheels right up to a polish so you start on one side of the machine and work your way to the polish end. These are a little expensive but you...

Yes, at least I think so. In this day and age of SPAM, telemarketing and everything else that invades my privacy I want to have the choice to opt in to someone's mailing list Even if I have purchased something from you that does not mean I want to receive email, bulk mail or the like. I buy lots of ...

I had the same thing happen to a piece of mine that was an important piece. I sandblasted with 120 SiC and it did not remove all of the scum/distortion on the surface. In looking back I should have tried using a surface grinder, in this case probably one of those diamond hand pads as a mechanical on...

A couple of things to do here. First I assume you have a new piece of Duraboard cut to fit the inside of the kiln. You did not mention how thick it is but I'm hoping that it is at least 1.5 inches. Second, you need to rigidize your board with rigidizer (colloidal silica). This is important as it wil...

Rigidizing is more a safety issue first and a durability issue second. Fiberboard is not nice stuff for your lungs. Check out this web site: http://www.unifrax.com/Products Click on Boards, then click on Duraboard products then Duraboard HD and then click on MSDS. Read it carefully! Using rigidizer ...

Get the book Contemporary Warm Glass by Brad Walker, the originator and keeper of this board. Can't find a better book anywhere.

That works assuming you don't have an AC unit. If you do anything that is major electric (hot water heater, AC Unit, Electric Range) you would want to be sure you don't have it kick on while you are firing or it could mess up your data. That being said, that is a clever and quick way to get a close ...

You can't tell by looking, either on the thermocouple or the controller. For the controller, I'm assuming you got some manuals or documentation with them. I would look through the doc's and at least confirm the thermocouple type required by the controller. Then I would call the place you got your th...

What type of thermocouple did you buy? I'm guessing that the Paragon wants a type K thermocouple. If you did not buy a type K but instead got a type J or something else, the thermocouple and controller will act like they are working together but you will get incorrect temperature readings. This soun...

Avery/Brock, If the controller was still operational and the oven was cycling down, ie you mentioned that it was at 300 in the morning, this indicates to me that the relay was in fact operating. In this case I would put my money on an intermittent thermocouple or possibly something wrong on the cont...

Here is a way to guess. The ACTUAL answer requires a little more data. Your particular kiln is a 120V/15Amp kiln. This means your kiln requires 1800 Watts or 1.8KW (KiloWatt) when it is ON. When you fire for a 10 hour cycle, your kiln is not ON that entire time. The most accurate way to measure your...

For an accurate schedule we need to know the thickness of your tiles. Search the archives for some firepolish schedules. I'll give the following assuming that your glass is 6mm (two layers) thick. 300dph up to 1300, hold for 10min AFAP to 960, hold for 1hr 210dph to 820, hold for 30min 105dph to 750...

If you can get the epoxy that they use to repair car windshields I would think that you might be able to spread it into the scratches and possibly make it go away. That epoxy is made with the same index of refraction of glass so it might work. Curing might be a problem as I've seen them curing it wi...

Brock, Do you know for a fact that the merc relay failed or was it in fact the control signal to the relay that stuck on? It is my understanding that a merc relay turns off from gravity thus cannot fail in the on position. The only way it could fail on is that the enegerizing coil was on thus the fa...

Hi Kitty,

Sounds like grozing pliers you use in stained glass work. In the days before Glastar grinders you had to nibble away your errors in cutting using a grozing plier or something of the like.
