1.Furnace Lighting Instructions   

1.Eliminated the need for sand mixing equipment.
Do not let the sand dry out and it does not need to be "mulled or remixed".

2.Eliminated the pyrometer.
By timing the melt after the last piece turns molten.

3.Eliminated the need for aluminum degassing.
Timing the melt and promptly pouring does not give
the melt time to absorb gas.

Our old furnaces (model L & S) were very heavy. The new Model A is twice as fast and uses half the propane!  

It is very important that people have the freedom and opportunity to create new things.
