Default Annealing Schedule Chart For Most Glasses?

Has anyone seen an annealing chart for most of the glasses we use? I have the following glasses in my studio, and am getting tired of hunting down the annealing schedule for each one when I decide to play with it:

Effetre
Lauscha
Vetrofond
Bullseye
Czech Glass
Gaffer
Boro
Satake
Kinari
Caliente
Pi Glass
System 96 (Uroboros)
90 COE (Uroboros)
Custom 94-96 COE (New Zealand)
Float Glass
Furnace Color (Kugler, Reichenbach, Zimmerman, etc.)

Wouldn't it be great to have ALL the numbers on ONE sheet?

So while I have your attention, when you're changing your annealing schedule to accomodate a new kind of glass, do you just change the temperatures and leave the timing the same?

I would love to have it on one sheet! Can I have a copy when you find it?

I must admit I do use the same schedule for czech, effetre, lauscha bullseye and uroboros.

Yikes! Ninety-five dollars!

Three libraries in the US have a copy and I have just placed a request to borrow it from one of them. Hopefully it is a circulating book and not a reference book. Will let you know when (and if) it arrives. Should take a week or so. The record says that there is a new 2000 edition, so I hope that's what I'll receive.

I've been working on a chart. I keep trying to post it here, but the formatting gets all screwed up.

The chart has 24 types of glass so far. Information columns include:
  • Product Name
  • COE
  • Annealing Temp (or range)
  • Strain Point
  • Sag Temp
  • Working Temp
Is that enough info? Anything else?

Hi Tink,

I recall discussing this on WetCanvas because I have a half finished chart I did a search over there and can't seem to find the thread. Post what you have so far and I'll see if I have some of the info that you haven't collected yet. Or just post the names of glassess that have the info on and I'll see if I have some of the ones you don't.

Make sense? It's a pretty big task and found it became overwhelming very quickly.

Cindy

Tink! Your chart will be a community treasure! Thanks in advance.

<<when you're changing your annealing schedule to accomodate a new kind of glass, do you just change the temperatures and leave the timing the same?>> I remember being taught that the timing was dependent only upon the size of the piece. So that would mean that, yes, you change the temp only (not the time) when accomodating a new kind of glass. Right?

Tink,

If you need to, send me the chart. I can get it converted so it will post here with no problem.

I agree. This would be wonderful. I can't help with formatting but I could offer to research or enter data if it would help.

Tink, This would be really helpful!! Several people have offered to help, can everybody send what they have and maybe one of us can compile it somewhere? Somebody's website, here, somewhere? I don't want to pay 95 (or even $69) for a chart (what i really want....). Thanks!! I'll try to find my book that I have somewhere that has most of the info in it (since I probably spent as much time looking here in LE and finding the book would have been about the same (it had to be packed for the church Xmas party in a box with other beading things- very sad and now mess in boxes).

Tink, I know we would all help. I know where my book is do we have a site to start a compilation, or should we just use this thread for a draft?

Just popping in to say that I hope this project gets done, one way or another. I don't feel any kind of ownership of it or anything: I would just like to see it happen. It would be a very valuable resource for everyone.

You guys posting here who have an interest in seeing this through should just figure out the best way to do it. We're coming out of some bad times here right now (John's mom passed away last week, among other things) so I can't do anything re: the chart right now anyway.

Maybe we can post everything here and then put it in some nice format and make a reference page for it, so it will be easily available for everyone (don't have to search through all the threads for it). Does it need to be in some sort of graph format, or can it just be typed and up loaded (I always screw up somewhere and all the lines never line up when it's just typed).

Tink - did this chart ever come into existence, and if so, where would I find it?

Tink, can you send it to Camie (post #1 and she can maybe put it in a format that can be posted (I have no idea of your computer skills). It seems like it would be a great thing to be posted on this website somewhere other than a thread....

I'm still looking for the chart I started. Here is a link to some great infor from Mike Firth. I confess, as I was putting the chart together, I had some difficulty deciding which temps were most important, and whether or not there were different terms for the same thing. For example: Sag, softening, working, slump.

I have this book ... smile ... I'll see what it has. I'm sure it will be missing the new glasses (had the book a year - it was more expensive than that when I bought it).

If you need any more info Tink pm me.

Default Glass Annealing Info Spreadsheet

Okay...

I've managed to find some data on various glasses (via websites such as Arrow Springs, Uroboros, Bullseye, Dogmaw glass, etc.) and the James Kervin book "More than you Ever Wanted to know about Glass Beadmaking."

I'm missing info on Caliente glass (though I've sent an email) and Pi glass (again, I sent an email). I have compiled a spreadsheet with the name of the glass, COE, annealing temp, strain temp, softening temp, working temp, and the source from where I got the info. There are still some holes in the spreadsheet, and some of the info is kind of vague (i.e. Arrow Springs annealing temp of 565-1050F...) But, it's a start, and I think the people who have worked with the glass could probably kick in their 2 cents for what they use to anneal their glass at.

I'd love to post it here, but it's in a Microsoft Xcel spreadsheet format, and I can't figure out how to get that onto here. If anyone has ideas for that, I'd happily email it to you. If we get everyone's notes together, we'll have one kickin' spreadsheet!!

I've included ASK, Bullseye, Caliente, Czech soda, Czech shampoo, Czech lead, Effetre, Gaffer, Kugler, Lauscha, Pi Glass, Reichenbach, Satake, Satake lead, Spectrum, Uroboros, Vetrofond, Wasser, Zimmerman, Boromax, Glass Alchemy, North Star, Pyrex, window glass, Armstrong float glass. I know it's not a complete list, but it's a start. As I've said, there are holes, some I only have the COE info for, and I'm hoping everyone else can kick in what they know about it. I've also included some tips such as Carol Anne's annealing temp, Dogmaw's annealing temp, etc. I have not tried all these glasses, I don't claim that this is perfect or that all of these numbers are correct. However, I have included the source of my information so you can take it as you wish.

I'll wait for someone to PM me to see how we can get this posted on here!

-Amy

Default great work Amy!

Amy, it does not appear that LE allows excel file uploads at this time. You can save your document area in excel as a word document. It will convert to a table in word, and I notice that the Manage Attachments button below will accept .doc files. Just an idea... if you aren't sure how to save it for word, i'd be happy to have you email the excel file to me privately and i could adjust it for you...

Hey people this is a very, very exciting project you are working on! I have taken the liberty of PM'ing SadiesJewels to make sure she notices what you're up to, as maybe she could fill in some of your gaps with the book she has. That's supposed to be a great book... kathy

Without reading all the posts I'd like to ask why you don't simply put it in a .pdf file? That way it's accessible to EVERYone. If you can't do that then send me the file and I'll do it.

You must remember that much as Bill Gates would like to think so, Microsoft does not rule the world and not everyone on the planet uses Word or Excel.

Darleen--

You are right, not everyone uses Microsoft products on their computers. Just remember this is a baby project (as in I just started compiling this list from this thread) and was doing so from my computer (a mac) with what I had available and what I am most familiar with (Excel--wanted the spreadsheet grids). As the list grows, as I get ideas and more input from others we'll figure out the best way to perhaps even get it posted here on LE so that everyone will have access to it.

It's still very much a work in progress, and I'm sure it will not be in a word or excel document once it's finished.
