Will the BGE fade in the sun? nm

Mine hasn't in eleven years. I have a 1999 model and a 2006 side by side, and you can't tell which is older unless you know the nuances of the older hardware.

I have a 2007 large, a 2008 large and a 2010 small and at the moment, I can tell which is oldest to newest by color(even if I didn't know otherwise), but I suspect after a few more years, they will have all reached the shade of green that will fade no more like yours have.

Well, I don't know about discerning eye :laugh: ,but maybe the crazing is more prolific in the oldest one and makes it look slightly duller than the newest one.

Mark,

I've got a couple that are a different shade than the others but have been that way since new.

dust in the crazing will lighten it, and since it's glass (essentially), you get the same pitting you would in a windshield, for example. all these things can "lighten" the egg. the color doesn't actually fade, but dust and imperfections effectively make it look faded

make any sense?

like scratches in glass.

i suppose there's some leaching maybe that can occur from exposure to the weather, but i know the color deepens when it is wet (like beach sand does), so i'm thinking it's more an issues of scratches and edges (from the crazing) that make it seem like the color is changing.

where's our ceramics conservator when we need him?

yo. woo doggies? any thoughts?

the glaze doesn't cover and protect the color. the glaze IS the color. that thing is white ceramic, covered in slip that turns green when fired. just as sand melts to become glass, the slip (i think that's what it is in this case) melts and becomes glass (glass-like is probably more correct).

the cracks and pits will not only trap dirt, but they scatter light, making it appear lighter. if you merely wet the egg, the dark color returns. like wet beach sand.

i'm betting john can tell us if there are glazes which can actually fade. but my understanding is that it isn't a case of UV fading like paint, or pigments leaching out from rain, but simply light scattering from pitting and scratches

woo woo woo - for once in my life I get to correct you, Jeff!!! Actually slip is the term for the liquid clay poured into the molds. Then the mold absorbs the liquid leaving behind the solid, but soft "green-ware". Then it is fired and then the glaze is sprayed or brushed on and the piece is fired a second time. It's funny but the color of glaze before firing doesn't look anything like what the final color will be.

Heck Ron, I tell him he gives out spot on advice 99.9% of the time(like a nice compliment)and he still starts to vibrate in his chair. :laugh:

you only get a half point... :laugh:

i admitted i wasn't sure if that's what it's called

"the slip (i think that's what it is in this case)"

hahaha

i've seen slip used as a decoration, applied on say a turned pot, so i thought that's what the glaze was

damn. and i made it all the way to november this year without being wrong, too.

(kidding)

Hey yall! It's my opinion the bge glaze will not fade to any detectable degree over time. The glaze surface may weather, dull and lose some gloss from exposure but the color should stay virtually the same and vibrant for centuries.... just look at 15th c. glazed tiles on the facades of Italian buildings.

The color differences between eggs old and new, domes and bases is very likely due to slight variations in the glaze formula. Noticeable when compared to eggs from different "batches" and is common in mass production.

That my story and I'm sticking to it. :~)

Lucky You! :~)

Okay. I'll remember that and get right on it.

I didn't think you were serious, but some people are really fanatics. :woohoo:
