"Black Beauty" Sand blasting Grit
Hi : I found this material where I work in a hotel, we use it as an
attractive public ashtray filler for people to put their cig. butts out. It's a real nice semi-shiny black color. I did some research on the product, it is called "Black Beauty" Slag Products by Reed Minerals. Its main use is for sandblasting and as a grit they use on roofing shingles. here's more info from the Reed Materials website: Black BeautyŽ Abrasive AKA: Boiler slag, coal slag Chemical Name: An amorphous mixture of Fe, Al, and Ca silicates Description: A black boiler slag abrasive with the following advantages: low moisture content, high degree of etch for permanent bonding of coatings, readily used in standard equipment in commerce, inert, fast cutting due to sharp angular edges, hardness, more economical,longer lasting and leaves minimum dust Typical Chemical Composition Silicon Dioxide= 47.20%, Aluminum oxide= 21.39%, Titanium dioxide= 1.01%, Ferric oxide= 19.23%, Calcium oxide= 6.80%, Magnesium Oxide= 1.47%, Potassium Oxide= 1.60% and Sodium Oxide= 0.62% Grades: Utility Grade #BB1043- A coarse grade used for tough blasting jobs Medium Grade #BB1243- Used for general purpose repair and maintenance blasting Fine Grade #BB2043- Used for new construction, light paint and rust removal, and for special maintenance applications requiring reduced profiles Extra Fine Grade #BB3063- Used to clean surfaces and create a smooth finish, Brush-Off Blast, or in a high pressure water blast system Typical Physical Properties: Particle Shape angular, sharp Specific Gravity (g/cm3) 2.7 Bulk Density (g/cm3) 75-1-- lbs. per cu. ft. Melting Point (°C) greater than 2300 Moisture Content less than 0.5% Conductivity @230°C (cal/s-cm-°C) less than 25 micro Siemens Mohs Hardness @20°C 6-7 Free Silica less than 1% Typical Applications: Used frequently as an sandblast abrasive on sea faring vessels, tanks, aggregate exposure, castings, structural steel, buildings, railroad equipment and bridges. Has anyone heard of, or used this material ? Do you think it would be safe ? I'm going to try a test in a small tank, but I dont have any test kits to see what it will do to water parameters, I'll have to use a fish or two and some plants as test subjects. I'll let you know how it goes, as this stuff is CHEAP ($8.00 /100#) |

It would look great in an aquarium. Unfortunately, it would almost certainly be toxic to plants and fish. My guess would be it would leech petroleum-like compounds and metals into the water, both of which are quite toxic. -coelacanth |

"Black Beauty" Sand blasting Grit
I did the exact opposite- White sandblasting sand (quartz). Set up about 6
years ago- never torn down. No 'black line', have lots of cats and loaches in an 80 gal. Also looks very nice- wouldn't call it natural but is nice counter point to all the bog log. plants and fish.
