The piece that haunts me.... (pic)

We all have one, right? The piece that was sold or given away as a gift, that you continue to think about and wish you had back? Mine might inspire some of you, way more talented than I, to refine this technique. So, I was experimenting with thick drops to make pendant lights. I didn't like one of m...

Re: Thermal shock problem, first time in 12 years, pics

Hi Bert, Thank you very much for your comments. You are right, any time the kiln is running unnecessarily it's a huge waste on multiple levels. Annealing at a lower temp makes a lot of sense given the mass of thicker glass. I will study more about this. I've seen you guys recommend the Graham Stone ...

Re: Thermal shock problem, first time in 12 years, pics

After a 26-hour firing cycle, I took a peek (at 175 degrees)...it looks like perfection, just tiny tiny bits of devit since this is the 5th firing. Given the mass, I will wait for further cooling before opening for a new picture. It's a Christmas Miracle! Thanks everyone.

Re: Thermal shock problem, first time in 12 years, pics

Thanks Valerie, I used Colorado Custom Stainless (303.433.2370). They made me a ton of different size casting rings, square, round, star--they would probably be able to do any type of shape (a fish shape would be cool!). Nice heavy gauge. I was able to give them dimensions of what I needed. It goes ...

Re: Thermal shock problem, first time in 12 years, pics

Marty....you were very observant, thank you! There is indeed a very thick layer of kiln wash adhered to the star legs...the thickest coatings are where the cracks started. I've ground off all the wash and am re-firing right now with your recommended changes to the schedule. I'll update tomorrow, tha...

Re: Thermal shock problem, first time in 12 years, pics

It's my own schedule, I should have just put in 3:00 but it's my rush to get close to 3 hours (programming the rampmaster) and what's a few extra minutes. Why does the up-speed matter when the cracking is happening on the downside? Thanks

Thermal shock problem, first time in 12 years, pics

Hi Everyone! I've been a fusing hobbiest for over 12 years, this is my very first thermal shock issue that I'm trying to solve. My kiln is a 12-year old Evenheat, it has been a total steady eddy...absolutely no problems at all. It has about 500 hours of firing time I would guess, with nothing done o...
