glass casting

New Mexico Clay's tutorial on glass casting in a clay mold. Fire the clay mold 100 degrees hotter than you plan to use it.
I fired the bottle glass to 1600 degrees @ 500 degrees/hour. So it took roughly 3 hours to reach that temperature. Then I held it at that temperature for 30 minutes. Next, I fired down as quickly as possible to 960 degrees, and annealed for 3 hours. The reason you anneal is because the glass is not uniform yet. Some areas may be hot, some may be cool. Annealing time will depend on the thickness of the glass.

Great tutorial. I`m just wondering about two things.. Did the mold survive the process, and if so how many more could you make with it? and when you put the glass into the mold, it looks like green bottle glass.. but the end figure is more blue? is there a special reason for that?

@carkirsch77 3 жыл бұрын

Hannipp The clay mold usually does survive the fire. If you are working with “dental” quality plaster or silica, doesn’t! But you have more detail.

@mikefromspace 9 жыл бұрын

If you polish the part with a wire brush wheel on a grinder or drill to remove debris, then re-melt the glass with the back of the sculpture up this time, on a flat surface ofcourse, can this smooth at some point without becoming a puddle of distorted nothing?

I just done a little snooping around ..there are several misconceptions about molten glass...one person said platnum was only material that would not stick to glass.Graphite is used in making molds for hot pours .It can be used in this type of melting in microwave too,

@g-rated7667 5 жыл бұрын

I think this is done later by doing a firing in the kiln that gets it hot enough on the outter layer of the glass, but not enough to completely melt it. The lizard would need to have hit feet on the ground in order for the top of him to melt slightly, giving that glass coat shine.

This is pretty much exactly what I was looking for. I make my own clay sculptures and have been wanting to make molds of them for glass fusing. Question though - what happens if I fire the mold I am making too hot? Will it break? Is it possible to do it too hot? I am still learning about this mold making for glass fusing/slumping etc. - Heidi

@NmclayAlbuquerque 7 жыл бұрын

The hotter you fire the more brittle the mold is and it may not give you as many firings. The great thing about this is you get to re-use the molds many times.

I’m very new to firing anything. When you fired the mold you went to cone 4 and when you fired the glass you went to 1600 degrees. Did you use a ceramic kiln for the mold making, then a glass kiln for fusing the glass or did you use a ceramic kiln for both firings?

@sanslabel 9 жыл бұрын

nadaadecirr Microwaving clay is not advisable. it has to dry thoroughly before firing it to bisque temperature. Any moisture within the clay will turn to steam in a microwave and potentially blow up inside it, and most likely wreck it. .
