Re: Adjust firing schedule after multiple firings?

it is heat work that is causing the chemistry of the glass to change.
I do not fire multiple firings. Do it in one firing and you won't have the problem.

Re: thermal shock issues

you have heat loss issues. Somewhere in that kiln you have a draft of cool air getting inside is my thought. Check your kiln. I may suggest the following may help. Get a really bright battery operated light. Put it inside your cold non running kiln in a blacked out room and look for light escaping a...

Re: Digitry Controllers

Never assume anything with a kiln.
You should be checking your connections for any signs of discoloration regularly.
Turn off the power first!

Re: Digitry Controllers

I've used Digitry controllers for 40 years. Only problem I encountered was allowing a sending unit's wire to get too close to a kiln and melt resulting in an internal fuse in the controller to blow. Since it was a Little Fuse, it was tricky to track down and find. What might be your problem is when ...

Re: Spray mold one day - fire on the next day?

I don't use Boron because once you do, you cannot go back to much cheaper kiln wash.
If Boron is supposed to last through multiple firings, and it is just like kiln wash as a separator, delay will not be an issue.
Now leaving a coated mold around for weeks in a dusty study may change your results.

Re: Frit size choices

powder tends to be self insulating because of the air between the granules. if you have a range of sizes of grit, then they can nestle into the spaces between each other. bigger granules will in general be clearer as trapped air can make a piece not look as clear. However why change if what you are ...

Re: Mixing it up.

Before everyone goes off on a tangent to reduce energy usage in an effort to halt natural climate change, give your head a shake. Man is not the driver of all the variations in climate and nor is carbon. Take a look at this site for a logical explanation of it all. Perhaps Australia, being close to ...

Re: Multiple high hest firings

When Bullseye first started there were some colours that you could fuse but try a second firing and it would break. Now the description I believe is 3 full fuse firings. Since fuse firings are nowhere near those temperatures you are way over any chances of stability. I only fire glass twice for that...

Re: Paragon GL24 kiln roof element installation

Tighten the wires in the usual way: Yes tighten the wires. Leave for a long period of time. Retighten the wires and repeat until you can no longer retighten the connections. The copper will move during the above process and if not done can result in burning of connections and necessitate element rep...

Re: Glass not filling void in lost wax technique

sprue sprue sprue and more sprue. High speed may cause cavitation where the glass hits the mold. Chances are you won't be able to consistently control the speed given the thermal characteristics of different molds. Float glass? why bother unless you are wanting a devitrified look. Eye candy here: ht...

Re: Pottery Wheel

Which one will be more pleasurable to use? smoother quieter etc. Then buy that one if both have the features and power you think you need.
I really dislike the noise of operating machinery. You will have to listen and try them both.
What are you going to try making some Higuchi vase forms for glass?

Check out building recycling sources for the tiles but of course when you look for them, the little identifying marking on the back may be covered in grease from the chicken fry restaurant they inevitably were removed from. :lol:

Re: How to Fire Dichroic and Retain Colour

Best of all when you get a piece of gorgeous dichroic glass people wonder why you want to charge more for it or just like Barry said you don't want to sell it. Everyone assumes in this world that everything comes from a factory and it is produced simply as required. I think the best way to describe ...

Re: Light weight Kiln Shelf

Armstrong Ceramaguard ceiling tiles are usable BUT they can heat warp, dent easily and also break easily enough when picked up 'wrong'. A regular kiln shelf will stay flatter, won't dent and won't break easily when picked up. My take is to use the regular kiln shelf and accept your kiln firing will ...

Re: How to Fire Dichroic and Retain Colour

The colour you see face on will not be the colour you get when fired. The colour you get will be closer to the colour you see when you tilt the coating. If you are trying for a bright blue, good luck doing it consistently as the coating companies produce variations from sheet to sheet. The only way ...

Re: WIFI monitoring of RTC 1000

If you just want to monitor from point A the kiln to Point B, there are security cameras and screens that are wireless and don't use internet
Swann and Lorex ones come to mind. Basically they are visual and auditory baby minders or unannounced visitor warning systems.
