Since 1937, Hubbard-Hall has been setting the pace for the metal blackening industry. The development of Black Magic, the first single-bath blackening process for steel, initiated a string of innovations.
One of the biggest innovations when using Black Magic Infusion is your ability to reduce cost. With this product line you can lower cost per finished part, less waste due to overspray elimination and less set-up and maintenance to equipment.
Using our chemistry, you are able to create a wide range of colors through chemical reactions. These products are not a decorative coating but a true conversion of the metal surface that won’t peel, chip, or flake while contributing little or no dimensional change.
Hubbard-Hall’s Black-Magic® line of hot black-oxide products is frequently used to produce a true durable black oxide conversion coating on steel, stainless steel, and copper alloys. These essentially dimensionless coatings create very decorative, highly durable, black finishes that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection.

Hubbard-Hall’s series of room temperature Black-Magic® products use a reactive chemistry to form an appealing black finish on steel, aluminum, and zinc alloys. These essentially dimensionless coatings create a very decorative, durable, black finish that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection. The room temperature process offers energy savings and convenience over hot black oxide while sacrificing some corrosion resistance and durability when compared to the finish formed by a hot black oxide.

The Black Magic finish develops a true conversion coating, converting iron to the naturally occurring black iron oxide compound called magnetite (Fe304) that will last indefinitely with proper care.
A consistent black oxide conversion coating is always desirable, but when the finish is not satisfactory here are issues that might be the cause.
Black Magic is an innovative single-bath blackening process for steel. As a true conversion coating, Black Magic yields an attractive, long-lasting decorative finish that won’t peel, flake or chip
When issues arose in getting a consistent finish on the part, the manufacturer called in Hubbard-Hall to see what they could do in helping blacken the part to a finish that met and exceeded expectations.
“Hubbard-Hall stayed focused on finding us
a solution. I was impressed with their determination and communication to our team.” – Tech Manager
Black Magic Infusion is a hot black oxide process that protects steel against corrosion. It produces the darkest black available without a sacrifice in quality.
Antiquing Solutions
The Mi-Tique® antiquing and metal coloring products are used to give an aged appearance to decorative hardware, bath fixtures, some jewelry, and other decorative accessories. Through chemical conversion, a variety of metals including copper, brass, bronze, nickel, silver, and pewter can be oxidized to produce black, brown, and green patinas. By varying time and concentration, users can achieve multiple shades of color from light brown to black. Tumbling, rubbing, or relieving the surface to highlight lettering or create contrast on designs, can create additional effects. See Hubbard-Hall’s Mi-Tique® 1792 antiquing solution in action.

Mi-Tique is a room temperature antiquing liquid formulation for copper, brass, and munz metals.
Through chemical conversion, a variety of metals including copper, brass, bronze, nickel, silver and pewter can be oxidized to produce black, brown and green color patinas.
Regardless of the metal involved, a number of problems arise in
antiquing operations due mainly to poor housekeeping techniques.
