Metal Slumping Molds
for Glass

You can use these for two things:

1) Use this stainless steel ring to hold your frit, crushed glass, to shape desired when firing. We supply the basic round or square or triangle shape. You can also bend to your custom shape. This flexible band can be bent by hand to any shape, round, squares with rounded corners, ovals, etc. The square style holder has right angle corners, but can be bent to make a rounded square. Coat with separator and sprinkle frit, strips or pattern bar pieces, and then fire. Click here for more detailed isntructions.

Special expansion slots allow metal to expand, preventing glass form breaking when cooling. This expansion slot is critical. Our competitors' don't have these. I don't see how it could work without one. This is needed because as the glass and metal cools, the metal will shrink more than the glass and will grab the glass so tight it actually distorts the metal band and you can't get the band off.

After firing the edge will be flat but rough. It may need an extra firing to fire polish the edge. Reusable. These are often made to order - you order may take longer to process if you order these. We can make custom sizes for you, no special custom charge.

2) Place a glass sheet on top and heat. The glass will drop through the hole. Stop it before it hits the shelf or continue heating and let the glass touch the shelf to make a flat spot. Glass needs to be a bit bigger than the metal ring. Practice and Experiment on this one for sure
