Go To: Subject: New in UK - Art Glass Show
The Art Glass Show is a new UK selling exhibition for Contemporary Glass Artists, to be staged twice a year at Haydock Park Racecourse, near Liverpool and Manchester, in their ground floor Lancaster & Sandon Suites, with room for expansion as it becomes necessary. Initially room for 67 tables (or equivalent floor space) at just £54 - we want this to be affordable to those just starting out as well as those who are well established. October 5th 2014, then April 19th 2015, and October 4th 2015. We have over 20 years experience in staging events of this sort - website under construction, facebook page with more details at https://www.facebook.com/pages/The-Art-Glass-Show/1488992831319649

What are the technical reasons you like the EC crucible better than the Guadaloupe ones?

Thanks,

Eric

Thanks so much for your well considered input.

Being new to the studio building experience I am relying heavily on the community of gaffers (like you) with real world experience.

I clearly have some more thinking to do.

Hello,

Couple of things.
I like the 80# Engineered Ceramics Crucibles... they are basically the same dimensions, but cheaper and better.


Look for model# 5564

For elements, that size melter seems to work good with 11 or 12 ga. Kanthal A-1 elements.

I ran 3 banks of 3 elements ea. at 4.7ohms (each element) in a series/parallel circuit. In this configuration each bank was 14.1 ohms. With using a 240 volt line, if one of the elements went out, which would cause one of the 3 banks of elements to go out, my melter would still work well enough until I could shut it down for repair.


Regarding question #2, I haven't used those products much actually, but I'm guessing they will not be ideal for hot face applications at the 2000F+ level... the main reason being safety, as duraboard is a fibrous product.. see the
MSDS info for more info.

Why not use a light castable for your lid?

I do like Skamol Board for various solutions:

We are designing/building a 80 lb wire melter in the Mayne Island style. We intend for this to be a VERY energy efficient top gather unit, 40" Dia x 26" H.

We are hoping to extend element life by using a variostat to adjust input voltage to be just sufficient for our usage style and turn down to a minimum during idle time.

The design calls for a Guadaloupe Glass 14" crucible http://stores.intuitwebsites.com/crucibleconnection/-strse-13/FC0014/Detail.bok in a 16" octagonal chamber.

Lid is to be Insboard/Duraboard on the hot side, backed by Dynaguard microporous and FibreFrax.

Help Needed:

1. Suggestions for sources and models of wire elements needed?
2. Is Duraboard or Insboard better and which specific board offers the best price/performance?

I am building a 80 lb wire melter.

Does anyone have any opinion in using one product vs the other (same max temp ratings for both)

Hello and welcome. I sure don't know all the books, but it kind of depends on what kind of book you are looking for I guess. Here is a few good ones.

Hot glass Techniques:
Schmid's books:
http://www.glassmtn.com/press.htm

Equipment Building:
Dudley's book:
http://www.joppaglass.com/book/Lit_page.html

Henry's book:
http://glassnotes.com/

Those are my standards and enough for this "welcome" category. If you'd like to talk further about books, I'd sure be interested, but perhaps we should do that within the forum category that you are interested in learning about. Click on "Categories" and select the category you are interested in finding books on and start a new topic there if you like.

Always good to have new users!.. this forum is relatively new and still a bit slow in conversation, but it does now have about 800 registered members and growing.

Glad to have you aboard.

Hi everyone!
I'm art glass student from Russia, I have found this forum casually. Actually I'm just try to find some books about art glass in English. If you can advice me some, I'll be very grateful. )
And sorry for my English.
