Re: Beginner questions

Regarding the Primer - this discussion has been made before. Bullseye says their primer(not PRimo) should be washed off and re-applied after every use. Hotlines/Primo says NOTHING regarding when to remove. If we assume PRimo is good for at least one use, then they both are single use. At very least....

Re: Re-fire brittle glass

The tips are probably just brittle. Refiring won't help them, other than if you do a full fuse and cause them to retract(losing the sharp tips. Opening the kiln: extremely pointless to look in the kiln between 100-800+f. You can thermal shock(break) a piece going either direction in that range. If y...

Re: kiln elements

The Kiln Book by Frederick Olson has a decent section on electric kilns and calculating electric element lengths, etc. *Get the 3rd edition.

Re: I need castable mould materials to melt plate glass into a disc.

I doubt I can cut tempered glass. But I can split it. I also saw videos of splitting circles from squares. I think that is much less difficult with 1/4" glass than with 1/2". So, my task is to fuse two 1/4" pieces of glass together and slump them, hopefully in the same cycle. Freeing...

Re: I need castable mould materials to melt plate glass into a disc.

Devitrification is not about cleanliness, it's about the glass being at a high temp for too long. No, bubbles won't float up through the glass like magic, the small bubbles could take days to reach the top, if ever. 1900f is not high temp for a ceramic kiln or a mixed media kiln. Those go to 2300f T...

Re: High Temp Powder Coating

Hi, I have a Paragon Kiln - Ovation 10, and my husband wants to powder coat his headers (high temp) it will have to go to about 1200 for 10-15 minutes. I make a living with this kiln and am afraid it will hurt it, does any one know if it will hurt my kiln. Thank you all so much. Lori Powder coating...

Re: I want to melt glass scrap into a disc.

OP - Google glass table tops - Someone will custom cut a piece that size for less than $75 each. Maybe double down and get a few to save on shipping.
Unsolicited advice - don't try this(molding your own). Nobody will 'post' you up the total learning curve required.

Re: Buying Bullseye Glass

I usually save my pennies to make large-ish orders with BE, for maximum discount. I'm in USA so no customs, and even with BE's shipping, I am usually still 20% under any mail-order retail(or Delphi which is about 50 miles one away). The mail order would then have shipping added on. Delphi would requ...

Re: is spray A dangerous?

Five gallons of borax solution will last until the dinosaurs roam the earth for a second time. :) I mix one pint of hot water with enough borax to saturate the water. Let cool and pour off the liquid which is the devit solution. That amount lasts me years (but I son't do whole sheets). Barry Agree ...

Re: Removing sticker 'ghost marks'

I think the ghosts occur similar to how you make glue-chip glass: spread hot hide glue on glass, then as it cools it rips the surface a little. I think the ghosts are where particles of the adhesive dried and disrupted the shiny surface by pulling at it. idk. I've had same experience - they pretty m...

Re: is spray A dangerous?

There is a comment by Ed above about using boron as a dip for pieces with light devit. Can someone talk more about that and also where do you get boron? Thanks for any info. 4-5 cups borax (one box if 20 Mule Team) 5 gallons distilled water - heat up to coffee/tea warm, borax dissolves better. Pinc...

Re: Playing with drop vases

Thanks Kevin. Yeah, some we keep the tops on, others cut off. We like breaking, re-arranging and remelting the cut off pieces to make very similar sibling pieces or sets. I've made a few using an escape plan. And a few that couldn't escape - good-bye dear ring. :(

Re: out of the norm and need firing schedule

^ I'm with Brad, you can just fire as is. But cleaning and laying them out might be more satisfying from a design aesthetic - or save them to use as design elements in a few different pieces. :-k I've made those "worms" before, never seem to be that satisfying in situ(their original as fir...
