Admittedly, I'm a little bit confused on your video where you're heating the outside plaster shell in order to remove some of the wax, rather than concentrating the heat from the bottom side. I thought the plaster jacket would prevent most of the heat from penetrating.
Hi there, this material is not plaster, it is Alumina which is a high temperature refractory material. It has very different properties than plaster and the flame is applied directly to the mold in order to 1) cure the ceramic bonds of the mold 2) remove there wax
Heating the outside plaster mold work with mold made with silica/plaster and water or just works in the one you indicate? I've never seen this method of wax lost before (heat the outside with torch)
Hi love the video. I noticed you mixed the whole container. I was wondering how long will the mixture last in storage if you seal the bucket properly. Another question I had is if your casting bronze do I need to preheat the investment before I pour the bronze ? Thanks
Thank you for your questions! Once the bucket is mixed it the paste will last for several years. If the mix dries out you can add more water and remix to the desired consistency. For bronze casting you do nit need to preheat the mold.
The blue glass is a piece of Bullseye sheet glass broken into pieces. If primed with kiln wash or another primer all types of glass can be used. These molds are also used for bead making and hot casting
This material is made of Alumina which is a type of high temperature ceramic. The application process and wax removal is different from the traditional method of plaster silica mold making

Awesome thanks
Hi, I should thank you for this informative video. I wonder something that how this oven called. How can I find an oven like that?
Its called an annealing kiln
Hi are you able to make reusable molds ? If your casting can be relaased easy ?
Yes, if the mold has no undercuts and is primed with a release (kiln shelf primer, graphite, boron nitride) the mold can be used for multiple castings
Using this bullseye release make you loose most of the fine details in you glass piece.
Using plaster moulds will be cheaper and faster.
What kind of glass can you use.?

This material? What material? You don’t say.
Zircar Mold Mix 7 ( www.luminarglass.com/mold-mix-7.aspx )
What is the difference between this and plaster silica?
This material is made of Alumina which is a type of high temperature ceramic. The application process and wax removal is different from the traditional method of plaster silica mold making
These seems like a very expensive way to cast glass. Equal parts of pottery plaster and silica flour and you're done, steam it out and off you go.
so is the bird carved from wax?
yes! brown sculpting wax
