Would agree with vasart as attribution but but would like more opinions to educate myself further.

Hi Chris and Roger.

Yes Vasart - and its a late one.

The main clue is in the setup - you will see in picture 2 that the canes stand proud of the ground. Thats because at Vasart they didn't have a glory hole so when reheating the gather in the mouth of the furnace prior to picking up the setup, it didn't get hot enough to enable the cane setup to sink flush with the ground.

The second clue is the blue/grey tint which is due to an excess of decolouriser ( usually managese ) having been added to the batch. This occured quite frequently at Vasart but hardly ever at Strathearn.

Why late? well look at the base - its fire polished and Vasart used to rough grind the bases until late on in Vasarts existance at which point they started experimenting with fire polishing. It proved a success (ie took less time than rough grinding) and was adopted as the standard finishing process when Strathearn opened its doors.

Hope this helps

Derek
