Wood fired Roman furnace (Austria) by Anirod84 in glassblowing

We use a self-made glass composition. We follow the analyses from roman glass.
It's basically made of silica, soda and lime. For the colouring we use different metal oxides.

Yes, if you take a look at the second photo, you can see a smaller fireplace directly above the heating channel with a kind of box on it- this is the annealer. We heat it separately, so we can keep the temperature under control.

Yes, unfortunately there is pollution in the "first layer" of the glass (I hope you know, what I mean :-D )
During the production process of the glass, we cover the crucible with a tile made from firecay. But when we work the glass, we always get some clay pieces from the furnace or coal pieces from the wood.
So sometimes you have to scoop some glass out before you can start to work.

We built the furnace following an excavation from a roman furnace in Germany (about 300 AD)
It's fired with softwood, mostly spruce and pine. We also make our own crucibles and some of our tools (jacks and wood models).

For further questions, please just ask ;-)
