Let me show you how i prefer to burnout my ceramic shell investments. In this method i use a propane kiln that allows me to capture most of the wax. This is the first part in a series that will show different ways to burnout.

"I know I'm covering probably a little to much" NO, no not even remotely, I love your videos because you get into the granular detail that provides the information to actually learn about the process! Never change!

Cool, Ill keep with flooding you all with detailed info. I promise, more videos are coming soon.

@NomadArchitecture 3 года назад

Thank you. I have watched a load of YT videos from people who do not know what they are doing and who get to the end and say 'now to review why this failed completely. It is nice to see one from a pro. But I wish I had watched a bunch of your videos before we tried to cast my son's final art piece last night. We tried to burn out then pour in one heating. The metal was ready before it was fully burned out, we decided to go for it anyway and managed a very fine geyser of wax jetting out of the top and the metal reaching about 1/3 of the cast. Today he goes back to school, I am left making another mould! I have a background in ceramics and guerrilla kiln building but metal casing is a whole new level. Thanks again.

@LunarburnStudio 3 года назад

We are coming from the same background, I started in ceramics and its still the basis of how i approach my foundry process. Feel free to ask me questions, happy to help if I can.

@NomadArchitecture 3 года назад

@@LunarburnStudio Thanks, we will have another go tonight. I already burned out the wax and all looks clean and white. fingers crossed. I am slowly working through lots of your videos so will see what you have covered before asking dumb questions (I know how this goes, I get a lot of questions on my channel!). But thanks again, this is youtube doing what it does best.

I am doing plaster mold investment currently and have a very basic burnout/curing oven that I converted from an large old 4 burner BBQ using a 20psi regulator and DIY furnace controller. As I am looking at upgrading from plaster to ceramic shell your information has been very useful. Keep up the great work!

Eric, another thoughtful and generous presentation. Will check out source for the mits for handling heated ceramic shells. Do you have plans to present the boil out wax method? I used it with success. It is simple and efficient. As of last December I have gone through the entire process of ceramic shell casting for the first time. Have enjoyed and benefited from several of your videos. Thanks!

@LunarburnStudio 3 года назад

Testing a few things, but yes will be showing the boil-out method in a couple of videos from now.

@jokubaspijusvildziunas5627 2 года назад

Hi Roy!, I am a foundryman from Lithuania. Could I ask to share more about boil out wax method? I have tried it with torch, but it gives a lot of cracks.

@fishtinandcopper179 2 года назад

Really great information in all your content, thank you for your generosity in sharing this. Creating fume is not really an option for our location is there anything to be aware of when using a boiling water bath to remove the majority of wax before placing in an electric kiln?

@LunarburnStudio 2 года назад

Depending on the shape of the pattern/wax you might want to create escape route for the waxes either by addition venting or drilling micro-vents. Remember the wax will float up not run out.

@pierrevanheerden9575 3 года назад

Thank you for your detailed explanation of why you use your methods. I continually have cracks in my shell due to improper heating. This video has just come in time as I wanted to quit. Just one question though, up to what temperature do you pre-heat your shells before casting? Best Regards

@LunarburnStudio 3 года назад

Your pre-heat temp will depend in the thickness of your pattern but typically I shoot for a temperature of 1200-1400F for 3/16" (5mm) patterns (thinner the higher and thicker lower) when I pull them from the kiln. The temp might be a little higher than I need but it gives me some extra time to get my shells set before I pour them.

@libormatula3616 3 года назад

Thank you. I like your approach and passion to metal casting by shell method. I would appreciate information about gas burner and also after burner. I also tried to contact Remet company in UK but they do not response.

@LunarburnStudio 3 года назад

I will be doing the follow up on the burnout kiln this weekend. Glad your finding my videos helpful!

@mf_martina Год назад

Hey! What is an efficient way of buying or acquiring your metal, in this case iron? Also, I absolutely support the idea of a more detailed video about the subtleties of your kiln

@LunarburnStudio Год назад

It is possible to buy iron ingots but most of whats melted at community iron pours that are running Cupolas brake up and melt down salvage/recycled radiators, bathtubs, sinks and with furnaces with big throats, brake roters.

@roelmohren2899 Год назад

Hi Eric, very very good video's your making. You give so much very useful informatie. I also want to start with ceramic shell investment casting. How long you burn you shell after de-wax? To virtified the shell. Kind regards from Holland!

@LunarburnStudio Год назад

Depends on the size of your kiln and how many shells your burning out at one time. I typically burn out 1-2 shells at a time. After the wax has drpped out i wait for the black smoke to stop. Then cook for another 5 min. Try to hold my burnout temp around 1650 f / 900 c

@roelmohren2899 Год назад

@@LunarburnStudio Hi Eric, I whas thinking to build my own burnout kiln. With softbricks and I will use your design of pouringcups. Ik whas thinking when I make a hole in de bottem of the kiln, and I design this so, that the pouringcup fits exactly on it, so when the wax drips out it will not come in contact with the flame of the burner. Maybe it wil not catch fire. And underneath a small pan (air tight)where the wax drips in, when this will catch fire, it will not burn long, because not enough ogxygen. Will this work?

@chrissilliker8633 Год назад

Hey Eric I would really like some info on the building of the afterburner. That may be a good video for you to do. Do you know if there is plans on the web anywhere ?

@LunarburnStudio Год назад

Ill add that to my list. It works best on down draft kilns with the added burner placed in the flue. My kiln is currently an up-draft, it works OK but my new kiln im building will be a down-draft.

@katharinafitz450 3 года назад

Hi, I am currently trying to learn the ceramic shell process and wanted to ask what temp and for how long you fire the shell and for how long? My shells are quite fragile. I use quartz powderinstead of silica powder, does that make a difference?

@LunarburnStudio 3 года назад

I bring my shells up to 1650F/900C then hold for 10 mins or so. But really dependent on when the shell are white. If you have a gas kiln firing in reduction this will take longer. As for the shell, I am not familiar with quartz powder per say. What I use is Fused Silica which is fired quartz.

@jokubaspijusvildziunas5627 2 года назад

Hello, I am a sculptor from Lithuania, trying ceramic shell that is completely new for us. We have tried to burn out the wax with blowlamp, but it causes a lot of small cracks. You mentioned that there is possibility to boil it out, how does it work? Have tou tried it? Thanks!

@LunarburnStudio 2 года назад

working on a boil out video next. It works but has some limitations.

@LunarburnStudio Год назад

The theory sounds solid, just make sure there is some heat hitting the cup otherwise the wax could jam up at that point and crack your shell. Or you could take the step of de-waxing your cup only before placing it in your kiln.

How do you proceed for 3D print burn out? In a previous video your Skull is not wax but a 3D print. Do you use the same heat level and process when firing 3D print material, How do you avoid expansion of the print material causing the cracking of moulds

@LunarburnStudio Год назад

For the most part yes, same temps as wax, especially with the Polycast. Pla will burn out at a lower temp, but you still need to vitrify the shell at 1650F/900C

@anitalim Год назад

Where does the propane come from on the kiln? What if there's a crack in your shell after the burnout?

@LunarburnStudio Год назад

Propane comes from tanks, some are portable, some are not. Just depends on your studio space, zoning and building codes.
