Why do some people vacuum out the bubbles of the investment an you don't? I been doing this silica flour, dental plaster, water investment for a couple years off and on now with limited success. My issue is the molds will often crack. I wonder if I vacuum out the air in the investment as it's setting if it will increase the durability of my molds. I use homemade leaded glass and ideally need something capable of withstanding 2200f.
Thank you so much. What a great video. I don’t want to make a slump mold. Can I use this for an open mold? Where I place the glass in the investment compound open mold and melt it?
Thanks for your videos! Watched them all. Waiting for more microwave kiln videos. I’ve been dabbling a lot in ceramics, glazing and fused glass since I have watched your videos. Want more 🤓
@@CaptMike I need a kiln first, but have been studying and researching everything for 4 months now. I can't wait to finally own a small kiln soon and start creating. Thank you once again for your advice and tips🙏
Excellent video. So many times on TH-cam, people skip steps assuming you know what to do, when in fact, you wouldn't be watching their video if you knew what to do:-)
Hi Capt Mike, What’s the difference in making this mix an not needing a glass separator when fusing ,an the molds that we purchase that need a glass separator ? Also Do we have to pre fire these investment mix molds before we use them?
Good questions Lisa. I'm not sure why it works that way, but I did find out that the larger and more complicated investment mix molds could use a little separator. You do not have to pre-fire the molds, just make sure they are completely dry.

Hi Capt Mike, thank you for sharing this video. I was wondering if you are using the investment molds that you have made with float glass? Do the molds resist the high temperature associated with using float glass?
Actually I have not used them since the video. I have so much going on that I cound heavely on those who watch my videos to keep me informed on their successes/failures.
I'm not sure. What I would do is make a small mold, say a flat one and try to melt a piece of bottle glass on that. If the mold survives the firing and the glass slumps your in business. Let me know how it turns out!
First, yes you will need some kind of mold release unless the master is silicon. Vegetable oil works for me (most of the time). next is does the piece have a flat side? If the master is 3 deminsional the mold material will encase the piece and you will not be able to remove it. If it is flat on one side I place the flat side down (with a little petrolium jelly to msake it stick) and pour the mold mix over it. Hope this helps.
Yes. Here is a video I made on using ceramic bowls, plates & stainless steel to slump & drape. You could also make any shape you want from clay and bisque it. th-cam.com/video/Hf-QwSvosXI/w-d-xo.html
@@Alestorm5000 If you are looking for a way to make something to drink from you have two choices and each will take a kiln. The first method would be to make a vessel from clay and fire it then glaze it. Second, slump glass over (or into) a mold. If I knew what you wanted I might could help more.

I have never really given any thought to using vaccum. I'll see if I can find a video on how to do that and maybe learn something.
Thank you so much. What a great video. I don’t want to make a slump mold. Can I use this for an open mold? Where I place the glass in the investment compound open mold and melt it?
I think that will work. Let me know how it comes out.
Great tutorial! This video saved me so much time. Thank you so much. I really appreciated you posting your sources for materials.

Can I use Ultra Cal 30 in this mixture?
Not sure what that product is. I'll have to look.
This is exactly what I was looking for in order to make my own custom texture molds for my glass projects. THANK YOU, SIR!!!!
Thank you for wathhing my video. Hope it works out for you.

@@CaptMike I'm guessing, but if I had a functioning controler, I'd try to make a thin mix of the gips, and use that as seperator as a test.
@@CONEHEADDK Thanks for the comment.
@@CaptMike I hope to get an update, if anyone trys it. I expect to do some more casting, when I get my controllers repaired, or buy a new one.
Good vedio, thank sir, may i know can I make flower wase? Where I can get the mold to pour mixer.
its a refaractory plastre?
You might could call it that, I'm not sure.

Have you tried using the molds in your microwave kiln?
Yes, but not successfully. I am working on new molds right now. If they work out I will make a video on how i did it.
Thank you so much for sharing all that information. I'm new to fusing, and watching your channel helped me so much. Kudos.
Thank you for watching!
Can i use that mold for glass bottle melting? For 1200° kiln?
I'm not sure. What I would do is make a small mold, say a flat one and try to melt a piece of bottle glass on that. If the mold survives the firing and the glass slumps your in business. Let me know how it turns out!
Thanks Captain Mike! This was really helpful information 🙂👍
Thanks for watching!
Thank you so much for posting this! It answered all my questions about how to make my own molds for glass casting!🥰
Thanks for watching!
Tank you for the information and for you time
Thgank YOU for watching my video!
You don't have to fire the investment mold using these products?
No, just make sure the investment mix mold is dry.
Would this work for making a glass bottle?
I'm not sure. You would need some kind of a two piece mold for a botle or a glass furnace. Totally different skillset.
ok, i want to make a mold of a ceramic piece {sea horse} can i pour the mix over the piece, and will i need a seperator?
First, yes you will need some kind of mold release unless the master is silicon. Vegetable oil works for me (most of the time). next is does the piece have a flat side?

@@CaptMike yes thank you, the piece is flat and i have mold soap. i am hoping to make the ceramic molds first. I will start soon i hope
@@catheyfoss2890 Great. let me know how it turns out. I wish we could post photos here.
Very interesting video. Have you ever tried using a piece of bisque to slump a larger piece like a bowl or plate?
Yes. Here is a video I made on using ceramic bowls, plates & stainless steel to slump & drape. You could also make any shape you want from clay and bisque it. th-cam.com/video/Hf-QwSvosXI/w-d-xo.html
@@CaptMike Thank-you for your kind reply and links. Lots of great information and I will be experimenting.
Wonder video- thank you for all the info!
Thanks for watching!
Does anyone know what is poured into these molds?
Thank-you Capt Mike
Thank you for watching!
Great video thanks I never thought about making a mold until watching you!
Have you ever made a drinking glass with this method?
No, I think the investment mix would be too porous. just guessing.
@@CaptMike I don't suppose you could point me in the right direction for such an activity?

Very useful video!
Thanks for watching.
Is it good for flat glass bending??
I only tried with small molds, but it worked OK.
@@CaptMike This mold breaks after heating in the oven.
@@akhtarali9665 Are you using a microwave kiln? I have has a few failures using one.
@@CaptMike no
