First Attempt to Concave Slump

My first concave slumpings went awry because I forgot to account for trapped air in my molds. This is fixed by carving out tiny veins or drilling air holes through the mold.

The green rectangular glass was fused earlier in the week, you can see that here.

Concave Slumpings!

Soft glass: Yellow, Green/Blue
Recycled: Brown Flow

I successfully reused these molds with small vents carved out.
