Streaky 003126

Postby franking1818 » Tue Nov 07, 2017 10:39 am

One of the components of this streaky is cranberry pink transparent, #1311. This time I read the notes for each constituent color, and they says 1311 needs to be held for 2 hours at 1225. Is this also true for the streaky glass, or has the cranberry color already been developed in the process to create the streaky? I don't want it to turn brown!

BTW, you do a great job of not being snarky when dealing with questions that could have been answered with more and/or better research. In my defense, it sure is hard trying to teach yourself. I have lots of great books and I have taken many classes, but none of them really deals with very specific questions once we new learners are let loose on our own to dabble with glass.

Thank you!

Hey, thanks for the kind words! I totally understand how challenging it is to find answers to all these questions, and we are redoing our search engine right now, so it's harder than usual to find the articles, for people who don't already know where they are. Plus, we love helping people who are new or relatively new to kiln-glass--there is a lot to learn, and we understand and respect the effort required to master this material!

Re your glass, I don't think the cranberry will turn brown, but if it is already more or less the color you want (through extra heat work at the factory) you can just fire it as if it were a more stable glass, like cobalt. If you suspect that the cranberry has not struck, you could try doing that soak. I don't think it will turn brown. But you should cut off a small piece that includes pink (or lavender, because the 1311 tends to look lavender or bluish before striking) and test it using your planned cycle before you make your finished piece.

It already looks cranberry, but I test fired a little piece. I'll know around 2 a.m. :D

I tossed a piece of 003126 into the kiln with a project that needed to be fired to 1500 for 20 minutes. I am sad to say that 003126 darkened and looked brownish. Maybe I should have capped it because of course it drew up on itself. I guess I'll have to test it with a clear topper. I hope that works because holding it at the recommended 1250 for 2 hours is too high maintenance for me. :roll:

Do you really need to fire your project for 20 minutes at 1500°F for 20 minutes? We usually hold at process temperature for up to 10 minutes for basic vessel projects.

Also, it may be that the 3126 does not need to be held at 1250 for 2 hours. Try another test without the 1250 hold and fire the piece for only 10 minutes at 1475. That might keep your pinks looking good. Do test it with a clear cap, if you want the tile to keep its square footprint and not draw up (=dogbone).

1500 for 20 minutes - I was fusing something from the new "edge" ebook.
