Advanced Glass Forge help

I remade a glass forge in a steam chamber. It immediately broke (the ceramic pipe) after the first use.

What am I not doing properly?

I removed standing water, which would have been the transmittal.

This setup still breaks a pipe every so often.

You are cooling too fast the liquid glass inside the forge. Steam has a quite high conductivity among gases and that 13kg per tile of steam will interact quickly with forge contents same as the liquid on a floor. Glass forge needs to be kept in atmosphere of less conductive gases and on insulated tiles (at least that one tile under output port, which allows heat transfers between building contents and enviroment)

Trying to eyeball it, randomly once a cycle the contents will drop to 1500f. It doesnt explain much and is inconsistent. I thought I could recoup some heat from this. But am unsure of a decent setup for this.

[Angpaur]

Trying to recoup heat from molten glass will be problematic inside pipes or building storage. Let it spill somewhere on metal/diamond tiles and transfer heat via the tiles. This will also have an adventage of creating heat due to 4x higher SHC of solid glass compared to molten.

Dripping eh?

What about a chlorine room and the contents drip onto steel tiles which leads to a steam room?

Would the forge need to be on metal tiles as well to transfer its own heat unless it'll overheat?

Use sandbox/debug mode to experiment with this and you will have your answers.

Buildings doesn't transfer its heat with tiles it stands on. A medium is needed (gas or liquid). A single drop of liquid will be enough, just don't place it on a tile, which a building uses to exchange with enviroment heat of its contents. That tile needs to be insulated or mesh/airflow if you place building in vacuum to get perfect insulation for building's contents.

I have my glass forges in my industrial sauna and they work just fine (ceramic pipes/forge as well), never had a problem with breakage, so it's definitely possible.

Trying to get heat out of glass as debris is very slow, for removing heat from glass in a steam room quickly this is the design you're looking for:

Steel valve is set to 1kg/s to prevent breakage in the pipe

This is what I have so far. Chlorine room works, no breaks so far. I'd have to expand to make a pick up system, for now its all trapped in a vacuum to transfer all heat to the steam chamber.

AncientGammoner, whats your ambient steam temperature? I see lots of tempshift plates, which I thought wasnt supposed to be optimal around the glass forge.

[AncientGammoner]

Everything in this area (steam, pipes, forge) is 140C, steam pressure is 20kg. The granite tempshift plates even out the steam temperature across the room since it's 4 rows tall, ~20x30 tiles. Tempshift plates only interact with stuff through a medium (in this case steam), and the only thing the molten glass interacts with is the ceramic pipe, so I'm not sure what would cause enough of a temperature drop over that one segment to cause a phase change?

It is not the only thing molten glass interacts with. Contents of buildings also interacts with surroundings. So it can happen that molten glass inside the forge will go below melting point even before it enters the output pipe, which will cause immedient phase change in first pipe segment.

His steam is at even hotter temperatures than mine (which would only help), and glass spends very little time in the forge, it basically doesn't exist until the progress bar completes. I just painted in 1000 kg/tile -250C hydrogen using sandbox and ran the forge, still didn't break the pipe.

[Angpaur]

And how long did you test? Because I can see that after 15 times in 1000kg hydrogen atmosphere @ -250C an insulated pipe made of Insulation starts to break. If you want faster effect then fill with only 10kg of -250C hydrogen. Pipe will break after 4-5 times usage of forge.

[AncientGammoner]

I'm not seeing anything like what you're talking about, running the forge multiple times just heats up the room and makes the temperature difference more favorable, the first run where everything is -250C is worst case.

Here is situation at the beginning of test:
