Expensive Lessons

A friend recently commissioned me to make a pair of glass panels to go around a couple spitters on his pond. The project seemed simple enough. They did want A LOT of dichroic in the pieces. The bottom layer is black with gold irid. Top layer is clear. Design in dichroic is in middle. In my first att...

Re: Casting window glass frit

I actually have the same kiln and have had a very similar problem. I simply had way too much stuff in the kiln for a single firing. My shelves were too close together and I just didn't get good heat penetration and distribution throughout all the stuff. Ask your friend to make sure to have 2 inches ...

Re: ETS

An ETS does get hot enough to fuse glass. The guy at the power company told me that they get to around 2000F max temp. BTW the ETS are fairly compact - the unit I saw was about 2' x 2' x 1'. They store a lot of heat because they use electric elements which can get really hot and bricks (which can to...

Re: ETS

Hi Bert. I was thinking of you when I made this post. I remember you mentioning that your studio has some form of demand metering. Funny you should mention solar heating. My wife and I recently bought a piece of land in Pagosa Springs (south west Colorado). I found out about ETS from the electric co...

ETS

I recently learned about a device that may be of interest to some glass artists: ETS (Electric Thermal Storage). An ETS is basically an insulated box, filled with bricks. It has heating elements and a fan to blow air through it. The heating coils heat the bricks during times of off-peak electricity ...

"I about blew out my belly button helping get it that far."

I've been blaming my belly button geometry on my addiction to chocolate. From now on I think I'll tell people that its a tragic result of moving all my shop equipment into the basement.

Lauren:

The magless, pendants and earrings on my site are pieces I've done using vinyl masks to sandblast dichroic glass.

The patterns you can create are limited only by your imagination.

You'll need a vector file before you can do any cutting. A vector file consists of a bunch of line segments, each of which corresponds to a cut to be made on the vinyl. A square would just be 4 lines. Things like circles and letters become many small lines. The software that comes with the plotter w...

I recently bought a vinyl cutter. I too was looking at cutters by Roland. I settled on the Lynx 24. Got it from Sign Warehouse (http://www.signwarehouse.com/). Besides handling larger vinyl, the Lynx 24 and the larger Roland machines are faster than the little Roland and can handle thicker material....

Make sure your iron pipe is grounded. You didn't say what the iron pipe is for (I'm guessing its your air supply). Hopefully, you're not trying to ground your cabinet to a gas line.

Usually copper water supply lines make a reliable ground point.

You should have a water tub below the saw and the pump sits in the tub. Your water should be recirculated by the submersible pump (pump to blade to tub and back to the pump). My saw throws out a lot of water and I have to refill the tub every 15 minutes or so. I run my tile saw in the back yard and ...

I've done a few pattern bar pieces. I too have noticed the crud. It seems that every surface that has been in contact with fiber paper or kiln wash (three of the edge surfaces of your PB slices) need to be ground or blasted before using. I avoid the crud by sandblasting or grinding the bottom and si...

If by pressure pump you mean air compressor, then the rental guy advice in nonsence. The blast media never goes through the air compressor. As for recycling the media, unless you use a blast cabinet the media is going to go everywhere in all directions. There won't be anything to recycle. You should...

"Fail to Heat Alarm" means that it did not heat fast enough. What is your ramp up setting? A setting of 9999 will go as fast as possible - whatever that rate may be. A setting of 9000 means 9000 DPH and if you've got a ramp up rate that it can't actually do, you'll get FTH. Do you have top and side ...

I just got back from Bert’s kiln building workshop. After contemplating my navel for a while, my thoughts wandered to kiln evenivitee-tee-tee-tee (is that a word or a bird call?). Burt’s design calls for an element that is a straight strand of nichrome that zig-zags to cover the surface of the l...
