this is probably one of the best videos i have seen regarding the process for sure

Joe is a great teacher and his instructions are easy to follow. After 1 lesson, I was able to grasp the general idea of lost wax casting, and now I found my new hobby. Thanks for everything Joe... - Feather

A most excellent tutorial, Thank you for sharing.

Very nice to watch a video done in under 10 minutes that many would have done in an hour! Thanks!

thank you for this very instructive video

this is a really bloody decently done video simple and straight forward i now think i can attempt lost wax casting now

Thank you for sharing your knowledge

Back for another visit and a few more I am sure. I am getting setup to do larger pcs. 1 to 5 ozt but well done showing process. Thank you !

So awesome. Now I need all this stuff haha, I've been doing sand casting for awhile and never been really impressed with the details I can achieve. Can't wait to try this!!

Very clear and interesting video ! Thanks a bunch!

Great video there, helped me learn the age old technique that is still in use in the modern world

Great Video and summary! Thanks for sharing.

wow! beautiful presentation! well done!

Thank you for the "insights" into your craft.. (art). I had no idea :O)

You are a really good teacher.

Nice video been interested in casting its the final piece of the puzzle for my shop.

Great vid! Have 22in swing arm spring loaded caster like yours, for years was just on a flat board with no sides, but when I started having issues throwing 8-10oz of molten bronze in an 8 foot diameter circle around my driveway I needed something better. Have to admit it never occured to me to build a wooden box around it. Wanted something fireproof... Friend was getting rid of an old stainless steel pool filter. The bottom part is on about a 12 inch base, which brings the whole thing up to a nice height to stand and do the balancing of the arm and melting/casting process. Mounted the caster in the bottom, it just fits inside the filter bottom. Welded a plate over the hole in one side where the pipe used to come in. Right up underneath the caster inside the base I bolted a brake drum from a flatbed tow truck, about 20-odd lbs of solid iron. Keeps the whole thing nicely on the ground, no tipping or even any wobbling. Very stable, and the steel is about 3 inches taller than the caster, so no more metal spills! Put the whole thing up on a wheeled board about 3 in tall and it lives under the workbench when not in use. Figured out my metal spill issue was that the arm is actually a little small for the big 4in wide 6in tall flasks I use though, so I made another weight for it by pressing one of the existing weights into some ordinary playground sand (damp, and let it dry out) and then pouring it full of bismuth. Actually weighs almost exactly the same as the cast metal weights the arm came with! Solved my balance problem with the heavier flasks. Just needed that one extra weight.

Good Demo, Thanks for sharing.....~~

This video is recommended in my art book, we're studying the iron age in Ireland and they used this technique very cool to see!

Darn! that was a well presented instruction. Jut fascinating. Thanks very much. Too bad I went to Cal before you were in business, or I would have swept your floors to see it in person.

Pretty neat indeed. That centrifuge scared a couple years out of me and I'm 77 . I don't need any more hobbies, but this sure was interesting. Ken...Marina CA

thanks very good!

Awesome

Thank you

Thank you for this video and answering all the questions. I took a class last weekend where we just carved and the instructor took home the wax to cast in his home studio. No overview of the process so his instructions made no sense to me. I will look on your website for classes to take because you explain things and seem to have given training techniques more than a little thought. It's a 3 hour drive for me but i am now thinking it is worth it. Thank you again!

cool thanks

Super

Te saludo desde Colombia 🇨🇴✔️ S.A

Excellent video. I have 2 questions. Why does burn out take so long? Can you use a conventional oven?

good share for that ,silica sol lost wax casting

very...very nice....congratulations...... São Paulo - Capital - Brasil

Nice video looking for a one where you teach how to make wax reproductions

Thank you, that is such a clear and well paced video. Obviously you put thought and care into it. I do have one question. When you melt out the wax do you drain it from the bottom by inverting the flasks, or does the wax vaporise from the burn out in the kiln? A very noob question I know. But it is the only one I have in order to get a much more rounded understanding of the process. Thank you!

I'm assuming you'd normally have a lid for the centrifuge? I use this method and as soon as the metal is ready to go I put the lid on it and duck down behind the shield. On occation you can get some slag stuck in the feed hole or something else goes wrong and molten metal can go anywhere. Perhaps I'm over cautious?

Silvera Jewelry School Thank you for this educational video. I did have a question I was hoping you could answer for me. The plaster you use. Is it a special blend mix or it plaster of Paris? Just curious because I have seen other videos where the mold has to be broken open versus disintegrating in water. Thank you :D

Great video! Please tell me, what is that tiny hot pick-like (tiny soldering iron) looking tool you are using? It's awesome. Thank you for sharing your techniques.

A wooden splash guard around the centrifuge?

Interesting how experience saves you so much time and effort. I mix my investment in a plastic bowl with a wooden spoon. I know how thick it has to be and roughly how much I need, so I do it by eye. I then tap out the bubbles using a piece of wood, saving me the expense of a vibration or vaccuum machine. I also paint my waxes with investment before this process so bubbles won't stick to it.. When it comes to the burn out cycle, again, all this waiting for hours is unnessessary. Once my investment has hardened in the flask, I leave it about 15 minutes and put it in a cold kiln set to 149c degrees for dewaxing. I put a tray undernieth to catch the wax so it doesn't screw up the kiln. After about half an hour at that temp I remove the tray with the melted wax and ramp it up to 371c degrees. You hear all sorts of bubbling sounds initially but it soon calms down and you get steam coming out of your inspection hole in the door of the kiln. You wait about half an hour until most of the moisture has evaporated and the jet of steam subsides, I then ramp it up to 732c degrees, leave it for 1.30 hours and its ready to cast. I've got this 8 hour burn out cycle down to 2 1/2 hours and you don't have to leave you're flask overnight to dry.. I preheat my bronze and take the still red hot flask out of the kiln at about 600 degrees. I believe it loses about 100 degrees a minute so you have to get it in the cradle and melt your bronze as quick as you can. I use borax to help the bronze flow and know through experience when its liquid before I let it spin. Overheating it causes the metal to separate so you have to get it just right. I enjoy 100% success as long as my sprues are well placed.. Whatever methods you use to save time, safety has to be at the forefront of your mind. You can do hundreds of castings but it only takes one mechanical breakdown to send molten bronze at 1100F flying around the room. You always have to be safely behind a screen just in case and never let animals or anything else distract you.

Very good , to the point without a bunch of useless filler. Question ❓ where do I find the non bubble stuff that you sprayed on the wax??? Is it simply a lite detergent and water mix? BTW I would love to attend your classes , but live near Atlanta Georgia far , far away from y'all

Thanks for the informative video. Have you ever had any accidents with the centrifuge eg hot molten metal spewing everywhere?

Great video, but I have one question when you put the flask in the crucible is it warm,cold or how should it be? because I trie to make my first casting with a centrifuge and what happened was the metal pierced the plaster leaving the mold empty, so also what would you recommend me to de next time? Thank you

Great video, thanks for posting! I'm looking to cast a 2" puck of gold, and we're looking to use a lost wax method. The final part will be ~1mm thick by 2". Do you have any suggestions on casting something like this without a centrifuge? We have a vacuum oven (which was how I was planning on baking out the wax) and I was thinking that we might get away with some small vents at the edge of the puck if we set the investment into the vacuum oven when we pour it. If you see anything egregious about that method, please stop me before I waste a lot of time :)

do not forget to cover the inner surface of the cylinder with asbestos tape to facilitate the expansion of the jar ....

i like using a ultra small drop of dish soap in the mix. the bubbles and lumps are diminished drastically.

Very cool video. This is the first time I've seen a centrifugal casting device. When the wax gets melted out, do you collect it for reuse? It would seem rather wasteful to just burn it all. Is the investment a dangerous material? I'm guessing it's not plaster of Paris and may contain silica? I would love to have a go at this myself.

Great video, loads of useful tips. Thank you. Could you give me a rough idea of the total cost for all the big equipment needed. Vacuum table + centrifuge + kiln

I'm a little late to this video, but it's a great demo! Can I ask - I have the same kiln (just got it). What is your burnout temp schedule for it? I've yet to use it, and haven't figured out how best to use it compared to my homemade one I used to use (talk about a guessing game!). Any suggestions? Do you ever steam the wax out first? That's what I used to have to do with my homemade kiln, but my understanding was that with this kiln I don't have to. Thanks! Great video!

Well done but I don't use a spin type .

Just wondering what made you tumble the cast pieces before doing the end finishing instead of tumbling at the end? Also I was just wondering how long you usually tumble your pieces for?

Good morning, Joe. Is the plaster you use is refractory or common plaster?

Another question.What kind of investment heat plaster are you using for your flasks? Thank you.

Wow, this is actually a really nice video about lost wax casting! I have one question though: you've used a centrifuge for casting. Why is that? Couldn't just pouring the metal (silver?) into the plaster mold produce the same result?

Quick question. I’m a pretty good mold maker but just starting my research into metal casting. Do I need to use wax to create the investment mold? I feel I can create the investment mold by creating A silicone positive of my object that the investment can be poured around, than removes pretty easily. If the wax step could be skipped it would save so much time and effort. But I’m sure I’m missing something because I can’t find the answer to the question anywhere. My object “a slightly tweaked rubber duck” is just complicated enough to rule out other casting methods. Thanks in advance for you time, your videos helped me a lot.

i like that centrifuge is that something you built your self if so can you do a video on how to make one

great video, thanks for sharing, do you offer 1 on 1 tutorial ?

Do you give online classes? Thank you in advance for your time.

could you cast aluminum this way? :)

I never see lost wax/ spin caster make air vents for displaced air, I've been having trouble casting an 18 gauge thin piece that folds over creating a thin arch the metal needs to get over...should I be using air vents?

Very good videos. Very informative. Do you take jobs in for pay. I just am asking because I would like to make a drive sprocket in metal the size of a quarter but I am not that good in making molds.

molten metal catapult @ 5:42

hello, could you please tell me the solution you sprayed on the wax to prevent bubbles to stick? thanks!

Would you say the machine that vacuums out all the air bubbles was... a good investment?

Can you recycle the plaster from the water bucket by drying & crushing it back to a powder?

I did not see the main part...How do you do the wax models?

what is the solution you put into the rock tumbler barrel with the shot and jewellery?

Do you need a centrifuge to transfer the molten metal to the flask casting? Can you just pour the molten metal into the flask?

What kind of plaster is that? If you just poured it instead of doing the centrifugal system would u get too many voids?

Did you make the centrifuge?

What kind of liquid u use after casting to clean rings tell us plz

Very detailed video, I have two silly questions: 1. When you put the plastered flask in oven, why only the wax is melted but not the plaster? 2. Just curious, wouldn't the heated metal in the centrifuge spilled out when it's spinning? Thank you for the video again!

No idea if anyone will see this now but worth a shot! Just wondering at what stage you make the rubber moulds for re-use? And if theres any good videos you reccomend to do this? Also any suggestions on where to source metals for casting e.g. gold. Thanks!!

Joe, can you retrofit or purchase larger flasks if you were wanting to make something like a medallion that was slightly over 4"?

What is the brand name of the soldering iron that yo are using?

I guess someday 3D printing will really speed this process up. Maybe even silver printing the product in one step

What is that tool your using to put the wax on, the one your dipping into the hard wax....I've been teaching myself how to do this stuff but one if the hardest things to learn about are all the tools, no internet searches I've used are any good. I've seen something that looks like it even lays wax ( not a batik pen) but cant find it anywhere. I have a lot of questions, but never receive answers.

Doesn't mixing with an electric mixer introduce air into the mixture?

Your work is wonderful and is like our work a lot, I have a question Can I find a job in the field of the Rings industry in America or Europe, and how do 💍💎💍💎💍

Please reply with a parts list and links where I can purchase. (Centrifuge, vacuum chamber, etc.)

Hi I’ve seen a ton of the bases you attached your sprue tree to have a hole in the area you attach the sprue to. Yours doesn’t have that. I’m worried the metal will go straight out that hole in my investment if that makes sense. Have you seen the bases I’m mentioning?

What are the dimensions of your centrifugal wooden encasement?

was there a reason you didnt vacuum cast but instead used the centrifuge?

I want to make make a silver belt buckle. I got kiln to do the lost wax brun out. I got a oxygen/kerosene tourch, and made me top vaccum. Here is my question.: Hiw do I know that the solver is hot enough to Puerto it into the mold?

what tourch is best for casting?

Hi, what is the name of this white powder that is used? Thanks

Why spray spray and what kind?

What temperature in the kiln?

Amazing. Is just candle wax or something more special?

Investment.

what kind of plaster do You use?

How can i set this up? links please!

Could I melt a candle to use as my wax? Thanks!

a drop of dish soap in the mud prvents air bubbles, jsyk

No mention of Borax. Why not make rubber molds from wax model.

what is that powder?

what is the process to balance the arm?

Holy shit is that scary, so many other safer methods . Please put a disclaimer on this content. That spinner should have a lid.

Spinning the red hot metal just looked a little too dangerous, I was envisioning molten droplets being spattered all over the studio

I did this in college. I still don't know why it's called "lost" wax casting. It's removed... but that still makes no sense. In fact, the plaster is "lost" too, so...?
