How did the Ancient Roman’s make Glass?

- Glassblowing has remained pretty much the same for the past 2,000 years when it was first invented during the times of the Roman Empire. The biggest difference however has been the fuel source: wood. Getting a furnace to reach the high temperatures required is no easy task, check out the full video of my journey: • The Secret Of Ancient ...
I have heard that a downdraft kiln is more efficient since the flames burn entirely inside the kiln instead of wasting fuel by burning some of the flames outside of the kiln. Kudos on making your own glass furnace. I hope to do the same.
I have been wondering if you could get higher temps using charcoal, that is something that is way in your wheelhouse. You would just need a hot fire without much air to convert your wood into charcoal. The fuel source should then burn hotter.
I'm his main video he made about this he talks about why just wood was better. Mainly for time efficiency. His video was very interesting had some nice history lessons
Coals can hit higher temperatures if you have air constantly blowing on them, but just having a bed of hot coals without forced air, they tend to suck up all the oxygen around them and burn a dim red rather that nice bright hot yellow that you get when blowing hard on them.
Coals don't give off volatile gasses like wood. With wood, those gasses don't need oxygen immediately. They can find some oxygen to react with somewhere else in the furnace...
So yeah, charcoal has the ability to get hotter, but that doesn't mean it automatically does.
Damn I didn't thought about the Roman all Day and now this, thanks anyway
I got that lol
@@lluch13and I'm Italian so is pretty difficult for me to
Use hardwood, alder burns insanely hot
A simple duct fan and length of pipe into the base would suffice with any wood or coal.
I fully understand the arguments in the vid, yet charcoal is a viable option of the time since you made it "primitive" too. It may not have been used on a industrial scale yet that wasnt really the requirement for your progress in general i thought. So i wouldnt see tge issue with using it. That doesnt make this excursion into the topic any less interesting
True, I could have used it, and I did in some of my previous attempts. However the conclusion I got from everyone I talked to and researched is that using wood produces the exact same result if your furnace is being run properly, as as it's directly producing the charcoal itself. I likely could have gotten the same result with directly using charcoal, but it's an extra variable I'd likely need to learn how to adjust for through multiple attempts. While every reference I found of successful ancient glassmaking I've found has been with wood.
@@htme that is understandable, thanks for taking the time to respond ;)
I wanna know how windows were made. Working a hot glob of glass is one thing - but relatively square, flat panes? They didnt have molten metal to lay it on like we do now
Romans
Spaniards use broom brush plants rather than solid lumber
Think it’s safe to say what with the Forrest fires on Hawaii that all you need to melt glass is a open field grass fire.
But can you cast an obsidian dagger
Your like me but i (hopefully temporarily) lost my passion a long time ago, i used to truly be a jack of all trades learning ridiculous things and methods to make stuff myself for fun and as a test of my abilities which never have failed me but after my health took a turn i dont have that drive to be tinkering at 4am and firing up the forge or making charcoal or wood vinegar or shine the list goes on.
And not only health reasons but monetary reasons money isn’t like it used to for me so that ruined it too
Just need to put in that work. It's honestly not that difficult when you have access to knowledge that the real creators didn't. I'm sure you researched and Google everything but they didn't have that option
I thought most of the glass at one point in history was made with peat. I wonder how they used the peat for the fuel...
They burned it! It's full of organic material and quite flammable. They would cut it into rectangles, compress it, or burn it crumbled.
Was a highly industrialized process involving lots of people in classical Rome. Doing all that's necessary by yourself is almost dark magic 😅 You probably didn't reach their level of productivity, though 😎
It was a Roman glass it was almost indestructible but the Roman ruler at the time killed the man if I would have been alive then and he did that I would that a should have been executed for it because Roman glass is brittle but if you could have made indestructible glass he should have never texted a and just kept manufacturing and he would have been a filthy rich man
Instead of wood can you turn your wood to coal and use that instead.
There’s too much moisture in wood. Try charcoal.
LOVE HTME ✅✅✅
You also need more than one person and constant bellows
Surprisingly I got the best result when I didn't use bellows, and just built the furnace to have a natural draft. There's no evidence of bellows being used widespread for glass production. When you need to run it as long as you need to to make glass, constructing a natural draft furnace is much more efficient.
@@htme interesting! I tried making my own furnace to forget steel. Couldn't get it hot enough without constant being pumped in. Tried maple, hickory and rosewood. Couldn't get it there. Great furnace design then!!
