Dartington flame red FT76 vase
« on: April 07, 2010, 09:35:58 AM »
Bought this the other day, saw it from a distance, it stood out like a beacon. Luckily I didn't injure anyone in my headlong rush to pick it up.

Gorgeous tall shouldered vase with a turned rim, slightly flared base and polished pontil. A little under 10 inches/25 cm tall and 4.5 inches/11.5 cm in diameter at the base.

This is the larger of the two sizes FT76 was made in.

thanks for posting John  -  what a beauty :mrgreen: :mrgreen:   Personally, think I'd have been oblivious even if I had knocked a few pedestrians over ;D

Part of the reason it caught my eye was the folded rim, I am always on the lookout for Erik Hoglund's designs so keep an eye open for them. I wonder if the various folded rim designs of Frank Thrower were influenced by Mr Hoglund's? Many of FT's designs have Scandinavian roots.

Anyway, remembered this thread so here is a photo taken with U.V. light. Anyone have any idea why the glow is not uniform but in bands?

Different thickness of glass?????

Possible.

I wondered if it had something to do with some of the cadmium not being heat struck (assuming the rest underwent a chemical change after heating).

Anyone else got any bits of flame red Dartington they can stick in front of a U.V. light for comparison?

I'd think that was a slightly more feasible answer, John - it's an awful lot of change for a small variation in thickness - and given the competence of the lip, I doubt there's much variation in thickness.
I'm a tad ignorant about the colours produced by cadmium though. :pb:

You could use it to keep your short spaghetti in!  ;)

Might be worth poking Adam and asking him to look. You can see at the base where the heat hasn't quite struck enough, as there's an amberina bit, but I can't see it explaining the bands as the whole thing would have been stuck in the glory hole and turned.

What if the whole thing was not put in the glory hole - but just for example, the top bit, perhaps while the lip was being turned?
Maybe even more than once?

Bands go right around the vase - perhaps it may have been marginally cooler near the entrance to the glory hole???
You could keep long spaghetti in it too - as there's no lid, it wouldn't matter if it stuck out the top a bit!

You have to heat it all to turn it red, otherwise it's pale amber, like this

Ah-Ha.

So, cadmium makes glass amber until it's heated more, when it will go red - it's the metal behind amberina (I'd "got" that bit - just didn't know how it worked exactly!)

ok, I can retire for the day. That's one something learned. Thanks! :hug:
