Wood to Stone to Bronze
I started out making a clay Thunderbird, then casting in plaster, then pouring hot wax in and then gating/venting it. Then encasing it, "investing", then pouring the molten bronze, it's fun, I want to do something cool with this later on. Mine hasn't been poured yet, next week, this bronze pour was someone elses project. The other pictures are mine.

That has to be a great feeling to get to the basics of industrialism.
Not to mention the art. |

Question:
Since the intake pour and exhale air wax relief runners are on the same plane, and very close to each other, how does the weight/heat of the molten metal pour get to the lowest areas consistently? |

The object is upside down, the Bronze is poured into the Cup/wax and it feeds down the two larger runners, the bronze going to the bottom forces gases out the smaller vents and will exhale out the top. I may have over done it with vents but I don't think there will be any dead spaces or bubbles. Actually all this wax is burned out of the mold before the bronze is poured in, these are just tunnels in the investment/cement type mold. Everything you see there will be bronze when it is broken out, the vents and feeds-all the red wax- will be cut off.
That piece of plywood is pulled off before it goes into the furnace to burn the wax out. It will leave that cup looking hole in the top, in the pictures showing the pour it is going into that hole left by the big blob of wax. You can see the indention of the plywood around the pour hole.

Well done!!!
I've done a couple of weeks away at "Summer School of the Arts" and wanted to exactly what you are doing. I ended up doing glass blowing instead, but next time lost wax bronze casting. |

I really want to do something good in bronze but just haven't done anything worth it yet, this is just practice.

Thx. I had the pour backwards: (top down vs. bottom up)
btw, I'd guess those extra vents will help fill the mold faster, and with more consistency. And back of piece equals a quick cut. |
