BCS Brass Degasser is a professional foundry grade, copper, brass, &
bronze degasser . It is manufactured
by Asbury Fluxmaster of Utah Inc. and sold to the foundry industry as #761
Degasser. It is used to remove hydrogen from the molten metal.
What It Does:
Molten metal can have gas dissolved in it that can cause problems. This gas is usually hydrogen. Dissolved gas can cause surface imperfections when the gas comes out of solution (bubbles) into the sand. It can also lead to serious metallurgical defects caused by hydrogen embrittlement.
Degasser combines with hydrogen in solution in the molten metal, and drives it out of the melt.
How To Use It:
Use 3 to 5 oz. Degasser per 100 lb. of metal depending on cleanliness of the melt.
Apply 1/2 the recommend amount on the cold charge. When charge is completely melted, skim the dross and plunge the remaining degasser into the metal. The object is to have the degas bubbles dispersed as much as possible thru the molten metal. This should be done as the last step before pouring. If the remaining metal is allowed to sit before another pour it may have to be degassed again.

Adjust the quantity as required depending on the cleanliness, size, quantity
and holding time of your metal.
Fluxing Tool:
A good way to apply small amounts of Degasser to the molten charge is to use a fluxing tool. Here's how to make one.
