Glass has definitely been a long-term challenge on the channel. In today's episode, I'm attempting to make glass without using any modern tools. Let's see if I can pull this off!

    Hi. I'm a retired ceramic engineer. Use charcoal instead of wood. Form a thick layer of silica sand in the front center of the furnace. Make a depression in the center of the sand to form a bowl. Put your premixed ingredients in the depression. The pure silica sandmelts at a much higher temperature so you will end up with a pool of melt that is more fluid in the middle and will fork its own solid bowl. Draw from the fluid portion. Build the charcoal fire to each side of the pool. Good luck. I enjoy your efforts and they show just how much practice is needed to get things right.

    think so too that was one of the reasons why they chopped down the forest that existed before the black forest (it got its name from the excessiv use of needle woods for its reforestation since its fast growing wood, which could be used relativly soon), they made ALOT of charcoal for smelting iron from ore.

    Part of the problem with the quality of his items is that he previously hasn't been consulting craftsmen for each specialty, and in the few instances he has consulted experts, their input is largely ignored. (Or in the case where a "bow" was made, in idiot was consulted.) At the current level of tech, he should already have hardened files and carbon crucible steel for making tools to make the correct tools for all this work. Skipping steps in the tech is why all his work looks like a 6 year old made it with their feet.

    A tip for candling . If you start with hot coals and place them evenly across the bottom you can control the heat much easier. Then add fuel generally in the form of either a hardwood or or more Charcoal. When using softwoods the excess of gas some sometimes reduces the heat due to the fact that the draft is greatly higher than needed. Remember for every cubic foot of air that goes into the Kiln extra over what is needed, needs to be heated up and evacuated. Try to use hard woods such as oak and Maple as they will allow for higher BTU put per cubic foot of material.

A friend of mine in the viking reenactment community told me once that they would add ground up broken crucibles to the fresh clay when making new ones, so they would be stronger and withstand more heat. It might be worth trying out, since you seem to have a lot of spent crucibles.

    1) While I'm a little disappointed that Andy isn't the one upping his skills and refining his tools as much, I'm still really happy that he's at least outsourcing the relevant work to professionals of the trade, because seriously, it takes years to master things like blacksmithing, not to mention all the tools and setup it takes to properly get going, so while it isn't *really* in the right format for The Reset in total, it's still a far cry better than before. Besides, when you think about it, it wasn't some master craftsman that did all the blacksmithing, woodcarving, brickmaking, baking, bladeshaping, etc. etc. etc. but various masters of the different crafts, though there was obviously little bits of overlap here and there, so the modern forge aside, this is way better. 2) "Bendable! Poseable! The Alien AKA the "Medium Green Man"! GLOWS in the DARK!" I was obsessed with finding a frame I could read that on, hahahaha. Made me laugh when I finally saw it. Thanks for the little bit of humour.

    I see this mistake often on youtube, when people are trying to heat things up like this. People make these dinky, low mass kilns. You need mass to even out the heat, to hold it in, and to buffer (slow down) changes in temperature. The only reason modern, tiny, kilns work is because they have a freaking propane blower on them. At a minimum, especially with glass, I'd have double layer brick, but I liked how he eventually added some weight. You want mass. Get some straight up KG's in there. Then there's a problem of getting hot enough. This is a challenge with primitive methods. Modern times you just add a leaf blower and stuff it full of wood, viola. To do this in a primitive fashion, I think you need to make charcoal first. You'd need a mound of it. Then you should use a timed method to reach your temperature. IE: fill the chamber with charcoal, burn half it it, time this, say 10 minutes. Then on the regular top off the firebox. Consistency is key. You'd probably wanna add a blower somewhere in there if you can. Blowers are discussed elsewhere on his channel, but for the love of god man. Make it bigger ;P

    Maybe you need to add a large bellows to force more air into the combustion?

    try Roman concrete to mortar the bricks to improve heat retention

    Look back a few episodes. The bricks are a modern ceramic brick adequate and appropriate for kilns since he did Roman concrete already.

    I agree with many of the comments, charcoal would help with your temperature problem as would some kind of bellows to force more air in.

    Lead oxide is a better flux, especially if you want a traditional roman glass. Borax is used to make pyrex, which is a pretty modern glass, but it's maybe not great without a modern kiln. Lead is still used to make "Glass Crystal" because it allows the glass to stay liquid over a larger temperature range and trapped air bubbles to escape. For the romans, it also sweetened their wine as it turned to vinegar, so there's that.

    I heard that adding some wood ash to clay may make your pottery more resistant to thermal shock and make it more resistant to the issues you are facing at higher temps. You do need to wash the ash to try to remove the lye out of it, but if done correctly this may solve your issue.

    One of the problems with accieving the highest temperatures might be that you use cold wood. In glass factories in the 18th and early 19th century, the wood was first air dried for a long time in ambient temperature (months), then it was superdried and heated in a separate kiln specially for drying wood, before beeing fed into to the glass kiln while still hot (I guess the outside of the wood was allmost charcoal at a couple of hundred degrees) and the water content 0%. This way you don't waste some the glass kiln energy to heat and dry the wood before it catch fire. You also need to acciece stable temperatures... First up 14-1500°C to melt the glass, and keep it there for several hours, then slowly cool it down to about 10-1100°C working temperature suitible for glass blowing. I support the suggestions to build a kiln of larger mass to even out the temperatures. I see from 18th century glass factory archives that they spent 3 days of continiously burning wood (in an allready red hot kiln) from the crucible was refilled and a new batch of glass was heated, melted for a long enough time and then cooled to woring temperature.
