You are an incredible artist!!! So proud of how you keep on trying - and turn negatives into positives!!! I totally enjoyed this presentation! P.S. Maybe you should consider safety shoes when working on your projects ...
I had my failures also with the slurry....I looked when you crached the shell by your hands. As to me the bond between slurry/sand layers is not well enough. When you were puting another layers of the slurry did you brush the surface with a paint brush? Or even used diluted suspenda slurry with distilled water to first wet the previous surface? I got that information to do that way every layer from Eric from Lunarburn Studio. You just need to prewet the previous layer of ceramic shell before you dip it - then the bond is way better. I did even make a video regarding making a strong shell step by step.
I really like the idea of a brass lamp! Unlike the zinc ones that are prone to breaking, a brass or silicon brass lamp would last thousands and thousands of years !!!👍 I have an old heavy brass lamp made by Stiffel. Not sure but I think it is actually made of zinc plated in brass, maybe one of the Zamak alloys. Looking at the base it is much thinner than yours, probably they used metal molds and pumped em out by the truckload. Boring out a wider hole in the organic would be a challenge without a lathe but could be doable with a drill press by "step drilling" possibly or special long drill bits? Or alternatively, designing a core into the mold somehow? Special sand(s), thicker molds should help greatly. You will master the technique. I also loved the Bob Ross inspirational quotable quotes.❤
When I have used shell after the 5th or 6th dip I wrap the outside of the shell with a 20 gage stainless steel wire. This serves as refenforcement like rear in concrete
I like what you do, go and watch the 2 videos on RUclips of my son Peter Gazzola on lost wax casting. Peter makes the molds in plaster and refractory clay. at 50% then he cooks them and the wax comes out, he doesn't use all those chemical products that you use. However you are good. HI.
Thank you so much for showing the journey, I watch the whole serie. The bear looks terrific! Wow, by watching your videos inspiried me to hopefully one day do some metal sculpture in the future. Thank you and god bless!
Man, when that cast fell off the hanger and broke.... Oh, it just broke again! Damn!! What about adding fiberglass to the slurry with the sand? It just blew out... deviating! Wow, you pulled it off! Beautiful! Quite the journey, nice work.
👍👍👍👍👍👍 one thumb isn't enough, even hundreds aren't enough. I felt so with you after the second try, after the third my heart broke... but then that result... stunning... perfect... love it.
Hi lundgren, What do you use for your mother mold (outer shell) of your silicon mold for wax casting? Its the dark brownish black sticky substance that hardens? Where would I get it? thank !!! Love your vids
Hey man, I've seen your video of the things you wished you knew before making a foundry, and I appreciate how you covered the details. Now, I have my molds and wax casts, and plaster molds ready. All that's left is the metal casting (to see if my plaster molds are correct) But that's where my problem comes in. First, there's noone who actually does metal melting/casting services in my little town here in south africa. So I have to do it myself now, but that's where problem 2 comes in. I have all the meterials to build a furnace. The fireproof cement, the ceramic fibre wools. But I don't know the first thing about working with gas, and burners, and hoses ect... I've heard too many tales of gas explosions and fires, so now I'm really scared to try gas, especially without knowing what could go wrong, and why. (I don't see alot of videos on you tube covering safety rules in terms of metal meltimg furnaces, especially home made ones..) So I was wondering, could you do a video about the ins and outs of a gas powered furnace, the safety rules, what not to do and all that? I'll be really grateful (needless to say I'm a subscriber)
Be the Bob - we should all be the Bob. Wondering how much of a solid fill your wax was. Maybe too much, so burnout expansion had to force outwards? More of a wax shel might help? Anyway, mistakes are the best learning points. Like the use of safety sandals
Great looking at your process as you work it out. I believe the wax volume was greater the elimination vents. drilling whole in the thicker was bed will help with eliminating the explaining wax.
Love the plan and even the 'failed' outcome. How is that taking any organic item and turning it to bronze just makes it so much better? Maybe it's my love of shiny things. :) Years ago I was able to share workspace in the corner of a prototype casting workshop I spent way too much time just watching the professional foundry guys using every method of traditional and new cutting edge casting techniques. I think they used to build up their ceramic layers a lot thicker than your one. Also more wax sprues for structure support. They also had a few grades of media to coat after each dip. I guess that saves some of the slurry as the build up is quicker on the outer large layers. They also slowly baked the wax out in an oven. The ceramic shells were fully supported by sand during the pour. As for the sand support, I would vibrate it to ensure it is fully compacted and then place some heavy weights on the top of the sand. That way if the bronze does try break out of a crack it won't be able to lift the sand and have a big spill.
@@lundgrenbronzestudios true, but I wonder how many fails they had before they perfected it. Also the ones I've seen sitting proud of the sand seem to have a very thick casing. I guess it's easy to bury and will just give more chances of success.
Yeah needed some homemade mold release in there, I just use aluminum foil to make the part line. But half the fun is in learning this stuff. I made a drift wood glowing mushrooms lamp sort of like this.
With some experience as ceramist I could tell You that ceramics dont like to fast burning and one point heating. Heat not so fast and than wax will come slowly and to the end without cracking the shell. All comes to the happy end thats important
Здравствуйте, если у вас корковая форма для отливки не растворима в воде, воск в таком случае можно вытапливать в горячей воде без всякого растрескивания корковой формы, грубо говоря положи форму в кастрюлю и нагрей воду. кипение Н2О 100 градусов Цельсия, а температура плавления воска 60-80 градусов цельсия, удачи :)))
man that was hell of a journey, one I'm about to start on. Slurry does seam to be problematic an art in it's own right. my plan is to use fire cement with water to thin it down with a few spots of washing up liquid to brake the surface tension on the wax to capture the detail then backed up with sand and epoxy resin (I've used sand or bentonite and epoxy for cores and if you have the heat it burns out beautifully making demoulding really easy) for the casting I plan to pack my mould in dry sharp sand packed down with vibration. The advantage of my proposed technique is fire cement doesn't need to be fired and epoxy will withstand around 200 c meaning you can melt the wax out without burning it out and no need for vitrification .
I had to use a hammer and screwdriver to open that stupid bucket! My first 2 castings catastrophicly failed as well. We let everything co and glued it back together. Its still a failed project, but i have something to show for it. I don't think the sand was the problem, you just needed more of it. The part that was in the sand poured fine, you just need a taller bucket.
Who knew watching you make a lamp could bring so many highs and lows! When the first ceramic thing broke i think all our hearts broke with it. Im watching it with my kids and there were gasps in surround sound. 😂
@@lundgrenbronzestudiosis it possible to melt out the wax in the kiln at a low temp over a pan to catch the wax so you can remove it instead of burning it? Trying to understand so I don't set the local makerspaces kiln on fire by accident...
@@StephanieLynne0321 not in ceramic shell. If you melt it out slowly the wax will expand and crack. If you do investment casting you can steam the wax out and save it. That’s what I usually do. There are some who will boil out wax in ceramic shell, but I’m not very familiar with that technique.
@@lundgrenbronzestudios thanks for the info! I'm doing plaster investment, not ceramic shell so that's good to know. To stream it out in a kiln, I assume I should add some water in a bowl to get steam? And do you know if this damaged the kiln in any way? I want to make sure it's still fine for fitting pottery
LOVE your videos. Educational and inspirational!
thanks for showing us your process, mistakes and all ,look forward to your video conquering your problem and making the lamp
Agree completely. The lamp will be EPIC, and who else do you see man enough to not edit out all the little mistakes.

Ah. Stainless would have been a better choice. When I vitrified it in the kiln I think the wire mostly oxidized away.
Love all the Bob Ross quotes 😂😂 I feel your pain for sure buddy

I’ve seen some people pour without burning the shall in sand at all. Which seems very risky. Maybe I should have just made it thicker.

This was beautiful mate. Bloody great video and end result. Loved this
You made me laugh.
Thanks for that.🙂
🇦🇺🤜🏼🤛🏼🍀☮️😎
i like to wrap more wire around my castings. also in the end I put a maybe 1/4 to 1/2 an inch of plaster of paris to coat!
Yeah needed some homemade mold release in there, I just use aluminum foil to make the part line. But half the fun is in learning this stuff. I made a drift wood glowing mushrooms lamp sort of like this.

To melt the wax out, I got an old cheap oven. The temperature can be controlled better than a flame. The wax will melt out great.
Great stuff my guy!!! Being shopping in vevor for a furnance
Not only entertaining but a great teacher. Lot of paitence and attention to detail. Awesome content.

Bronzeeeee guuuuuiiiiiiiii and purple belttttt which is also bronze but u get it.
The only way to improve, is via failure.
2:33 - Mmmmmm, strawberry silicone is the best.
Weld a cast bird or scorpion on it, maybe a marmot
I ordered some suspendaslurry about 16 months ago..I still can't get the lid off..I think I'll keep on with investment casting.
😆. I’m told fumed silica will help with the cracking issue.

Have you tried this method before? Pouring hot metal on wax sounds incredibly dangerous.
What a journey! Thanks for sharing.

Very cool!
Awesome!
Interesting recovery from disaster! 😁😎 Nice!!
wax splashing on foot. that is me right there.
It doesn’t feel good.
I'm sure it's a failure we can all learn from!
how come u didt bern out in kiln ?
Too much wax for an inside burn. I didn’t want to burn down my garage.
