by way of interest as well as requesting an id, if possible.
Accustomed to seeing clear glass giving slight greenish reaction under uv, due to presence of some manganese - often included, apparently, to de-colourize some of the impurities in cheaper glass - a lot of the C19 Celerys produce this effect.
However, wasn't aware that, when proportion of Manganese increased then there is effect of creating attractive Amethyst or purple colour in the glass - such as this stick. This is one of the most attractive sticks I have seen - simple and a pressed piece only - but really good quality, with perfectly round concave pontil mark, beautifully polished in the middle of a ground and polished, completely flat base. Top is also ground and polished flat. 7.5/16" - 185mm tall. I only have the one, unfortunately. The green in the last pic. is really striking. Probably little chance of getting an attribution, but in anyone does recognize it please let me know, and thanks for looking.
