First Hot Glass Casting Pour at The Doug

[GWOSAPAT]

are iredescent Christmas bulbs made like this? How much training does it take?

[volgabest]

KLASS!!! PLEAS see my video!

Amazing furnace design.

Is the mold plaster/ silica? If so, did you have to bring the mold up, and hold, at a pretty high temp?

I've had extreme bubbling, when hot casting in plaster silica. I dry for a few days and then bring up to 1200 for 5 hrs before pouring glass at 2300 degrees.

Any suggestions would be immensely appreciated.

Great work.

@austnorvell Thanks for the great questions! Cam is locked out of commenting right now, as I have some issue with the acct and need to fix it. You can put your questions to him at dsap@artapult.com

also, check out our Ustream channel for more casting vids. user: artapult

Peace

you guys rock ... wow

The old man mentions "i need to get a bigger fernas and bigger kiln" Where can i get one? I need it sent to NZ Thanks JOHNO

This is really cool. Actually this is the largest work of casted glass I've seen. I am interested in the oven you have. I mean the second one, where U placed the mould. We had an order of a bath made from glass, but could not make it because of the furnace. where did you get it from?

[knarfoo]

Cameron design, and we built the annealing oven ourselves. all of our equipt. ( we a couple of exceptions) are designed and built in house.

We will be doing two construction projects in the near future. A larger dumping furnace for our casting facility, and a rebuild of our main clear furnace in the hot shop. i hope to have some good documentation of at least one of the projects. we'll see...

Do you intend to do follow up videos of it coming out of the oven, the cold work etc? Did all go well? I hope so! You can turn this into a video serial, release a new part of the process every couple of weeks!

[knarfoo]

Thanks for the Question! Yes, everything went well. you can see the finished product in "Pouring the Second Glass Table". We haven't shown any of the cold work process because we didn't think anyone would want to watch sandblasting. i am always amazed at the depth of people's interest in our process. it is really great! We probably won't do a serial though, i can barely get enough time to put up what i do (and I'm behind on that!)

So how long was the anneal?

[knarfoo]

About eight days. thanks for the question, sorry for the delay in responding.

[soreff]

Many thanks!

@knarfoo Hello, on something that thick do you start the annealing process at 900 degrees? Also, during the eight days, at what rate is the temperature dropping?

Why are everyone so happy seeing how glass is melting?

[stacyemma]

Well I for one think its a fasinating video. I am a great lover of glass and dabble a bit myself. I think its amazing how they calculated exactly how much glass they needed to fill that mould - or was that just luck ;0)

I would have loved to see the finished product though. BTW I would KILL for a kiln that size!!!!

[knarfoo]

I believe someone can, but it is not us! Boro needs more heat than we work with. I am sure they do it at Corning and other big places. In small amounts I think someone could do it on their own, but we would not be the resource for information on how to do it.

Sorry! Thanks for the comment!

Can one do this with borosilicate?
