The number of castings depend on the handling of the mold, I generally get 10+ casting from a mold that is handled with care

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

Yes you definitely can! You can also reuse the mold for more castings.

The glass was Bullseye Sheet glass cut into small pieces and the kiln was held at 1500 degrees F

This material picks up small details including textures

If the molds are open faced with no undercuts you can use the mold until the surface begins to lose detail. If the mold is properly primed with a release agent (kiln wash, boron nitride, graphite) you can get up to 20 or more castings before detail is lost

Zircar Mold Mix 7 ( www.luminarglass.com/mold-mix-7.aspx )

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.

Awesome thanks

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

hello! Unfortunately, to my knowledge there is no homemade recipe for Mold Mix 7/Mold Mix 6. You can try to purchase through Ed Hoy International, they may ship to Argentina

During melting the glass will turn an opaque orange, but once cooled clear glass will become clear again

@@luminarglassproductszrci4802 oh awesome, thank you very much 👍

Hi there, I am sorry you had a fusing issue. I would suggest doing a thicker coating of kiln wash. You can also try a different release agent, Graphite and Boron Nitride Aerosol Sprays work very well at preventing sticking and you can use a much thinner layer of release. As for the flattening out on the open side I think this is probably an issue with the firing schedule you are using.

Unfortunately we do not suggest dipping positives into the material. The material has fibers that help create the strong shell and when it is poured or dipped the fibers flow in the same direction. This created the potential for cracking. When the layers are painted on the fiber create a strong weave that allows the molds to remain strong and thin.

@@luminarglassproductszrci4802 Thank you for that valuable information. It's the little things that can make all the difference.

In this video micro-crystalline or sculptors wax is used as the positive for the mold.

Hi Jay, thank you for letting us know. We had a glitch on our end and the Website will be up and running today. i am so sorry for any inconvenience!

@@luminarglassproductszrci4802 Excellent, thanks so much!

You can purchase our products on our website (www.luminarglass.com) , we do ship to Australia. At this time we do not have any local distributors in Australia or New Zealand. You can use on clay if you use a mold release like Smooth-On Mold Release

Hi Jet, you should not put the mold mix 7 onto the ceramic directly, it will stick (if sticking happens it can always be removed with water). You can use a mold release before applying the mold mix, we generally recommend Smooth-On Mold Release.

The food coloring helps you to see where you are painting on the layers so each layer is an even coat

@@luminarglassproductszrci4802 Thanks!

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

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

Yes! Mold Mix 7 works when directly applied to silicone, it will peel off of the silicone when it is completely dry.

yes! brown sculpting wax

Its called an annealing kiln

The wet mixture can be sealed and kept indefinitely. If it dries out you can simply add a little water to re-hydrate it

Hi Michelle, in Leslie's personal practice with MM6 she prefers to use both kiln wash and boron nitride. You can use just one separating agent but this is the method Leslie has found the most success with

Hi there, this wax piece was made using a small soap mold.

Hi Suki! As long as inside of the mold is well primed with a release agent (Kiln shelf wash, boron nitride, graphite) the cast should be easily removed from the mold. If the mold is very detailed or has under cuts the molds will need to be broken to release the glass. I hope this was helpful!

If the mold is primed properly (with kiln wash or Boron Nitride coating) it can be used many times, I regularly get 5-10 casts out of an open faced mold like this one.

Hi Sprezzatura Glassworks, this was the first time this artist had ever poured into a mold this thin. It was an experiment not meant to be professional. Just part of our R & D process that we were looking to share!

This was a first go experiment. I believe the poor surface of this one is due to the primer not being completely dry and creating a texture when the hot glass touched it. Both this fish and the full size fish had no cold working.
