Re: Tiny Hole Saw Bits for a Dremel?

Caution drilling shell material. All marine life fills their shells with poison to slow down their being eaten by other sea creatures. Do under water, no dust and wear safety equipment.

Re: how to use this glass cutting tool?

Swiveling cutter heads can be good to follow curved lines but the rest of the time it is a pain even if you follow Toyo's directions of tilting the cutter back. Using a Thomas Grip cutter you can adjust the handle sizing such that you can hold your middle finger beside the head and get the best of b...

Re: Capped silver foil & fuming

The acid used was probably not hydrochloric but rather HF. That is most definitely a don't try at home!! It can eat the wires in your studio walls never mind burning your bones. I have experienced contamination by silver months later coming out of the refractories in my kiln. If you think of working...

Re: Fractures appeared!

It will be cheaper in the long run to cut your losses and dump the 96 and just switch to Bullseye. Every time you make something and it breaks months later is a financial disaster.

Re: The screw on running pliers.

This is for Barry.
When you have cut as many miles of glass as I have and are concerned with clean cuts and zero flaring you will adjust the screw.
The bonus is less stress on you hand.
However since you know what you are doing don't bother.

Re: The screw on running pliers.

cleaner cuts are made with a properly adjusted pair. Zero flaring at the start of the cut.

Re: Help me find this COE 82 amber powder!

Finally an area to explore to try and create glass like Brian Blanthorn created.
His techniques were most certainly not simple.

Re: Power failure

I should think you will be ok so long as your annealing times were correct.
Check with polarized filters and then you will know.
don't be in a rush to remove the pieces from the kiln.

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...

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...
