First success! I got one bowl and two stems from this casting session. The one on the left still did not invest properly. I fault that to the...
I just got a job polishing silver so we’ll see about that after not too long haha
Thanks, it's silicon bronze. Probably a very high silicon bronze considering how much of the crucible has melted into the metal over time (I reuse...

Updates First attempt was a simple test - a proof of concept - to see if this might work. I used plaster/sand since I didn't want to waste real...
I can drive pins through in various places. That should hold it good. I can't weld a seam but I can tack a pinhole
Without support pins the investment would still be connected to the core through the bowl, carb hole, and mouth hole
It can burn whatever, I've just been having people who frequent smokeshops (where they sell glass pipes) ask me to make a metal one, so this...
Another idea is to fire a clay bowl in place after casting, since part of the patination process involves heating the pipe up to around that temp...
I see. I have no way of welding that piece on if it were separate. If I did something like that it would have to be friction fit or something. I...
I can’t cast the bowl and stem separately as I have other designs that have artwork that flows along that seam. It needs to be cast as a single piece.
Hi all have a few questions here that I hope you'll be able to answer before I possibly waste expensive ultravest. I am vacuum casting a hollow...
Aluminum should be easy to hack up. The bronze is a another issue. It really depends on how big the ingot is. An angle grinder and a pack of thin...
Awesome. I tried this with pla. Cracked before it even reached 500°
I'm guessing defective. I have the same budget crucibles, treat them poorly and still have no issues like that.
Yeah pretty much. There are other ingredients but that's the basic idea. The fireclay I have is already a pretty good formula, so I won't be...
I suppose I'll have to mould and fire my own with the extra fireclay I have laying around.
2.5" diameter x 6.5" height I can remove the ceramic top exposing the raw chamber which is 3 3/8" diameter by 5.5"
I have clay graphite (typical foundry type) and pure graphite (straight wall, grooved for tongs) crucibles. I burn through the graphite crucibles...
Tell me about it, it gets worse with a 5 gallon chamber you burn through charcoal like a pack of smarties That's of course for bronze, aluminum...
