Uroroboros - I know them principally for their System 98 glass - 98 CoE.
However, they also make a 104 CoE clear.
So - let's give it a whirl.
Wow. This might be my new favorite clear.
I did nothing to the rods before using - just wiped off with windex and a paper towel. These came out pretty nice!
This is a base of Uroboros clear, rolled in silver foil, and encased. You can see I got a bit of yellow/gold from being a little hot, but over all, I manage to keep the silver largely, silver.
With the Effetre clear, I might as well be using gold foil - it will all change colour.
For sure, more experimenting is in order, and I do still love Zephyr - but this is one sexy clear glass!
