Narrator: CAST-IRON COOKWARE IS RENOWNED

FOR ITS SUPERIOR ABILITY

TO RETAIN HEAT AND DIFFUSE IT EVENLY.

BARE CAST IRON, HOWEVER,

REQUIRES REGULAR OILING TO WARD OFF RUST --

NOT SO WITH ENAMELED CAST IRON.

A GLASS-ENAMEL COATING ENCASES THE IRON,

MAKING THE COOKWARE ENTIRELY MAINTENANCE-FREE, FOREVER.

SINCE 1925, THIS FRENCH COMPANY

HAS BEEN PRODUCING ENAMELED CAST-IRON COOKWARE.

ITS HIGH-END PRODUCTS ARE RENOWNED FOR THEIR THIN WALLS,

WHICH MAKES IT THE MOST LIGHTWEIGHT CAST-IRON COOKWARE AVAILABLE.

THE SECRET -- THE MINERAL LEVELS IN THE IRON RECIPE.

AT THE FOUNDRY, THEY BEGIN WITH PIG IRON,

WHICH HAS HIGH CARBON CONTENT.

THEN THEY MELT IN A CALCULATED AMOUNT OF STEEL

TO FURTHER BOOST THE CARBON LEVEL.

THE MELTING OVEN HEATS THE METALS TO 1,520 DEGREES CELSIUS,

LIQUEFYING THEM IN JUST 45 MINUTES.

WORKERS ADD A POWDERED CHEMICAL

TO AGGLOMERATE THE NATURAL IMPURITIES IN THE IRON,

THEN SCOOP THOSE BONDED IMPURITIES OUT.

MEANWHILE, WORKERS MOUNT A TWO-PART MOLD TEMPLATE

ONTO A MACHINE WHICH PRODUCES THE SAND MOLDS

WITH WHICH THEY'LL CAST THE COOKWARE.

THE MACHINE INJECTS THE SAND MIX INTO THE TEMPLATES.

THE MIX CONTAINS CLAY, WATER, AND PROPRIETARY INGREDIENTS

WHICH MAKES THE SAND COMPACT WELL.

COMPACTION IS CRITICAL

BECAUSE JUST ONE SINGLE GRAIN OF SAND DISPLACING FROM THE MOLD

WOULD PRODUCE A FLAW ON THE COOKWARE.

IT'S ESSENTIAL THAT THE POURING TEMPERATURE

BE PRECISE AND CONSISTENT,

SO THEY TRANSFER THE IRON FROM THE MELTING OVEN

TO A TEMPERATURE-MAINTENANCE OVEN.

FROM THERE, THEY POUR THE MOLTEN METAL

THROUGH A MERE 1/10th-OF-AN-INCH GAP BETWEEN THE MOLD HALVES.

THE PROCESS IS ENTIRELY AUTOMATED

BECAUSE THE POURING ANGLE AND SPEED ARE CRITICAL.

THE MOLTEN IRON COOLS AND SOLIDIFIES IN 20 MINUTES.

THEN THE MOLDS DROP ONTO A VIBRATING MESH CONVEYOR.

THE SHAKING RELEASES THE CAST COOKWARE FROM THE MOLD,

ALONG WITH THE METAL THAT SOLIDIFIED IN THE FLOW CHANNELS

LEADING TO THE MOLD CAVITY.

THE COOKWARE MOVES INTO A CLOSED CHAMBER

WHERE A HIGH-PRESSURE GUN BLASTS THE SURFACE WITH STEEL BALLS

TO REMOVE ALL REMAINING GRAINS OF SAND.

AT THIS STAGE, THE COOKWARE HAS ROUGH EXCESS METAL

WHERE THE TWO PARTS OF THE MOLD MET.

SO NOW WORKERS SMOOTH AWAY THESE BURRS

USING A GRINDING WHEEL ON THE OUTSIDE...

...AND A GRINDING PIN IN THE TIGHT SPOTS.

THE COOKWARE IS NOW READY TO BE PREPPED FOR ENAMELING.

A MACHINE NOW BLASTS THE ENTIRE PIECE WITH STEEL GRITS,

MAKING THE SURFACE TEXTURE UNIFORM

SO THE ENAMEL WILL ADHERE EVENLY.

THE FIRST COAT OF ENAMEL

IS STRICTLY TO PROTECT THE CAST IRON

AND PREVENT IT FROM RUSTING.

ENAMEL IS A FORM OF GLASS.

HOWEVER, THIS ENAMEL IS ENGINEERED TO BE FLEXIBLE

BECAUSE METAL COOKWARE NATURALLY EXPANDS AS IT HEATS

AND CONTRACTS AS IT COOLS.

AFTER A TRIP THROUGH A DRYER,

THE ENAMEL GOES INTO AN OVEN

AT MORE THAN 1,500 DEGREES FAHRENHEIT

FOR ABOUT 45 MINUTES.

DURING THIS FIRING,

THE HAIR-THIN ENAMEL COATING BECOMES TRANSLUCENT.

THE SECOND COAT OF ENAMEL

COMPLETELY SEALS THE POROUS SURFACE.

IT'S MADE OF SOME 20 COMPONENTS,

INCLUDING ENAMEL CHIPS, PIECES OF CLEAR GLASS,

AND PIGMENT POWDERS FOR COLOR.

AN AUTOMATED SPRAY SYSTEM COATS THE INSIDE FIRST.

WORKERS WIPE THE EDGE

TO PREVENT THE PIECE FROM STICKING TO THE CONVEYOR,

THEN THE HANDLE

BECAUSE THEY'LL PAINT THAT A DIFFERENT COLOR.

THEY SPRAY THE HANDLE MANUALLY,

THEN THE AUTOMATED SYSTEM COATS THE REST.

THE IRON RECIPE CONTAINS A HIGH LEVEL OF THE MINERAL SILICATE,

WHICH HELPS THE ENAMEL ADHERE WELL.

ONCE AGAIN, THE COOKWARE GOES THROUGH THE DRYER,

THEN INTO THE OVEN AT MORE THAN 1,500 DEGREES FAHRENHEIT

FOR ABOUT 45 MINUTES TO VITRIFY THE ENAMEL.

ONCE THE COOKWARE COOLS,

IT UNDERGOES A FINAL VISUAL INSPECTION,

THE LAST OF 30 QUALITY-CONTROL CHECKS

THROUGHOUT THE PRODUCTION PROCESS.

ENAMELED CAST-IRON COOKWARE LASTS FOR GENERATIONS

BECAUSE IT DOESN'T WARP OVER TIME

AND REMAINS FOOD-SAFE FOR LIFE.

Narrator: BIODIESEL IS A MORE ECO-FRIENDLY DIESEL FUEL

THAT'S MADE FROM VEGETABLE OIL OR ANIMAL FAT.

UNLIKE REGULAR DIESEL AND GASOLINE,

PRODUCING BIODIESEL DOESN'T REQUIRE PETROLEUM.

INSTEAD, THE RAW MATERIALS ARE LOCALLY AVAILABLE

AND CAN BE RECYCLED FROM WASTE.

IF YOUR CAR HAS A DIESEL ENGINE, IT CAN RUN ON BIODIESEL FUEL,

USUALLY WITHOUT REQUIRING ANY MODIFICATIONS.

WHILE BIODIESEL AND PETROLEUM DIESEL

ARE SIMILAR IN ENERGY EFFICIENCY AND FUEL ECONOMY,

BIODIESEL IS MORE ECO-FRIENDLY.

FOR STARTERS, IT CAN BE MADE

FROM WHAT WOULD OTHERWISE HAVE BEEN WASTE --

FOR EXAMPLE, FROM VEGETABLE OIL

FROM THE KITCHEN OF YOUR LOCAL FAST-FOOD JOINT.

THE RESTAURANT SIMPLY DISCARDS ITS USED FRYER OIL

IN A RECEPTACLE OUT BACK.

EVERY FEW DAYS, A VACUUM TRUCK COMES BY TO COLLECT IT.

IN ITS CURRENT STATE,

THE OIL CONTAINS WATER AND FOOD PARTICLES,

MAKING IT UNUSABLE FOR BIODIESEL PRODUCTION,

SO THE TRUCK TRANSPORTS IT TO A FILTERING PLANT.

THERE, THEY PUMP THE OIL INTO A HOLDING TANK,

THEN HEAT IT UP TO DRAW OUT THE WATER.

ONCE THEY DRAIN THE WATER,

THE OIL IS READY TO ENTER A MULTI-STAGE FILTERING PROCESS.

FIRST, THE OIL GOES THROUGH A VIBRATING SIEVE

WHICH STRAINS OUT THE LARGER PIECES OF DEBRIS.

AFTER THIS FIRST FILTERING,

THE OIL IS ALREADY VISIBLY CLEANER.

NEXT, IT PASSES THROUGH A SECOND VIBRATING SIEVE.

THIS ONE HAS A FINER MESH.

THEREFORE, IT CATCHES SMALLER PARTICLES OF DEBRIS.

AFTER THIS SECOND STAGE,

THE OIL LOOKS CLEAN BUT STILL CONTAINS MICROSCOPIC DEBRIS,

SO IT ENTERS THE THIRD AND FINAL FILTERING STAGE --

PASSING THROUGH 20 ULTRA-FINE FILTER CLOTHS

WHICH TRAP ANY PARTICLE LARGER THAN ONE MICRON IN SIZE.

A MICRON IS ABOUT 80 TIMES SMALLER

THAN THE WIDTH OF A HUMAN HAIR.

THE CAPTURED DEBRIS LEAVES A MUDDY RESIDUE ON THE FILTERS.

THAT VEGETABLE OIL, WHICH ONCE DEEP-FRIED POTATOES,

IS NOW READY TO COOK UP SOME DIESEL FUEL.

ANOTHER SOURCE OF OIL FOR MAKING BIODIESEL

IS BEEF TALLOW -- OIL DERIVED FROM COW FAT.

BIODIESEL PRODUCERS TYPICALLY BUY TALLOW

FROM FACILITIES LIKE THIS ONE, WHICH SPECIALIZE

IN CLEANING COW HIDES FOR LEATHER TANNERIES.

SHARP, REVOLVING BLADES

SHEAR OFF THE FAT FROM THE BACK OF THE HIDE.

THE FAT DROPS ONTO A CONVEYOR,

WHICH MOVES IT INTO A STEAM-INJECTION COOK TANK.

THE TANK HEATS THE FAT TO A GENTLE BOIL,

EXTRACTING THE OIL.

EVERYTHING ELSE LEAVES THE TANK

AND DROPS INTO A WASTE CONTAINER.

THE OIL MOVES ONWARD,

PASSING THROUGH A TWO-STAGE FILTRATION PROCESS.

WHETHER THE RAW MATERIAL IS VEGETABLE OIL OR BEEF TALLOW,

THE BIODIESEL PRODUCERS

REFER TO THIS MAIN INGREDIENT AS FEEDSTOCK.

WHEN THE FEEDSTOCK ARRIVES AT THE BIODIESEL PLANT,

IT GOES INTO A HOLDING TANK UNTIL PRODUCTION TIME.

THIS DEMONSTRATION ILLUSTRATES THE PRODUCTION RECIPE.

THEY TAKE THE FEEDSTOCK

AND COMBINE IT WITH METHANOL, A TYPE OF WOOD ALCOHOL,

AS WELL AS WITH A CATALYST,

WHICH TRIGGERS A CHEMICAL REACTION.

A PROCESSING UNIT MIXES EVERYTHING THOROUGHLY

WHILE APPLYING HEAT AND PRESSURE.

THE RESULTING CHEMICAL REACTION PRODUCES A HARMLESS BYPRODUCT,

GLYCERIN, A COMMON INGREDIENT IN SOAPS AND COSMETICS.

PROCESSING CONSUMES MUCH OF THE METHANOL.

THEN THEY REMOVE EVEN MORE,

LEAVING JUST A TINY PERCENTAGE OF IT

IN THE FINISHED BIODIESEL.

TO ENSURE THEIR FUEL MEETS

INTERNATIONAL REGULATORY STANDARDS,

THE PLANT'S QUALITY-CONTROL LAB SAMPLES

FROM EACH PRODUCTION RUN.

IN THIS FLAMMABILITY TEST,

THEY HEAT THE FUEL TO 275 DEGREES FAHRENHEIT,

THEN APPLY A FLAME TO SEE WHETHER THE GASES IGNITE.

IF THEY DO, THEY HAVE TO REMOVE MORE METHANOL

TO MAKE THE FUEL SAFE.

IF THEY DON'T IGNITE,

THE FUEL MEETS INTERNATIONAL SAFETY STANDARDS.

BIODIESEL COSTS MORE AT THE PUMP,

BUT EMITS SIGNIFICANTLY LESS CARBON DIOXIDE AND MONOXIDE

AND 85% FEWER CANCER-CAUSING AGENTS

INTO THE AIR WE BREATHE.

Narrator: UNTIL THE MID-1800s,

PEOPLE FOLDED OR LAID THEIR CLOTHES FLAT

OR HUNG THEM ON HOOKS OR PEGS.

ONCE IT BECAME MORE COMMON TO STORE CLOTHES IN A WARDROBE,

SOMEONE -- HISTORIANS DON'T KNOW EXACTLY WHO --

INVENTED THE CLOTHES HANGER,

A HANGING DEVICE SHAPED LIKE HUMAN SHOULDERS.

SINCE THE MID 19th CENTURY,

HUNDREDS OF INVENTORS HAVE PATENTED VARIOUS SHAPED HANGERS,

MANY OF WHICH ARE STILL BEING PRODUCED TODAY.

THIS CZECH COMPANY MAKES WOODEN HANGERS IN SEVERAL STYLES.

IT USES BEECH, A HARD AND DURABLE TYPE OF WOOD.

THE DAMP LOGS AIR-DRY OUTDOORS FOR SEVEN MONTHS,

THEN GO INTO A KILN FOR THREE TO FOUR WEEKS.

DRYING THE WOOD IS CRITICAL.

OTHERWISE, THE HANGERS

WOULD EXPAND AND CONTRACT WITH TEMPERATURE CHANGES

AND EVENTUALLY CRACK.

WORKERS FIRST USE A BAND SAW

TO SLICE THE LOGS INTO 2 1/2-INCH-THICK PLANKS.

THEN THEY PUT EACH PLANK THROUGH A BROACHING MACHINE.

INSIDE, A TOOTHED BLADE PLANES THE WOOD,

RENDERING THE TOP AND BOTTOM SURFACES LEVEL AND SMOOTH.

NEXT STOP IS A GRINDING MACHINE WHICH CONTAINS ABRASIVE BELTS.

WORKERS FEED THE PLANKS INTO THE MACHINE ONE AT A TIME.

AS EACH PLANK PASSES THROUGH,

THE BELTS ABOVE IT SAND THE TOPS SILKY SMOOTH.

WHEN THE PLANK EXITS THE MACHINE,

WORKERS FLIP AND REFEED IT TO SMOOTH THE OTHER SIDE.

AN AUTOMATED SAW CUTS EACH PLANK IN HALF...

...AND TRIMS THE HALVES TO A SPECIFIC DIMENSION.

THE NOW-SMALLER PLANKS GO INTO ANOTHER GRINDING MACHINE

WHICH SANDS THE SIDES SMOOTH.

NOW THE HANGER SHAPING BEGINS.

WORKERS STACK 10 PLANKS

AND, USING A CIRCULAR SAW, CUT THEM TO THE SAME LENGTH,

THE ENDS AT A 60-DEGREE ANGLE.

THEY MOUNT FOUR PLANKS AT A TIME ON A MILLING MACHINE

AND CUT A TONGUE-AND-GROOVE PROFILE ON THE EDGES.

THEY'LL LATER CONNECT THE HANGER PARTS

BY FITTING THE TONGUES INTO THE GROOVES.

STACKING SIX PLANKS NOW,

THEY TRACE A HANGER-SHAPED TEMPLATE ON THE TOP SURFACE,

THEN CAREFULLY FOLLOW THE TRACE LINE WITH A JIGSAW.

EACH PLANK IS NOW ROUGHLY SHAPED INTO A HALF A HANGER,

WHICH THEY CALL A LAMELLA.

THIS PARTICULAR HANGER IS DESIGNED FOR DRESSES,

SO THEY MILL A GROOVE IN THE SHOULDER OF EACH LAMELLA

FOR GARMENT STRAPS.

THEN AN AUTOMATED MILLING MACHINE

REFINES AND FINALIZES THE HANGER'S SHAPE,

SMOOTHING THE ROUGHLY CUT WOOD IN THE PROCESS.

NEXT, WITH STRONG CABINETMAKER'S GLUE,

THEY COAT THE TONGUES AND GROOVES OF TWO LAMELLAS,

THEN FIT THEM TOGETHER ON A PRESS.

THEY LET THE GLUE DRY FOR A DAY,

THEN SAW THE POINT OFF THE TOP.

THIS CREATES A FLAT AREA

INTO WHICH TO INSERT THE HANGER'S HOOK.

THERE'S ALREADY A HOLE FOR IT THERE,

MADE WHEN THEY MILLED THE TONGUE-AND-GROOVE PROFILE.

NEXT, THEY SAND THE JOINT TO REMOVE EXCESS GLUE

AND SMOOTH OUT ANY NICKS OR TEARS IN THE WOOD.

THEN THEY ROUND THE ANGULAR JOINT.

TO SEAL AND PROTECT THE WOOD,

THEY NOW SPRAY THE ENTIRE SURFACE WITH VARNISH.

WHEN IT DRIES, THEY DO A ROUGH SANDING,

THEN APPLY A SECOND COAT AND LET THAT DRY.

MANY CUSTOMERS WANT THEIR LOGO

PRINTED ON THE HANGERS THEY ORDER.

THE PRINTING MACHINE

COATS A LOGO-EMBOSSED RUBBER PAD WITH INK.

A SPONGE DABS THE PAD,

THEN STAMPS THE LOGO ONTO THE HANGER.

FINALLY, THE HANGER'S IRON HOOK --

IT'S EITHER NICKEL-PLATED FOR A SILVER TONE

OR BRASS-PLATED FOR A GOLD TONE.

WORKERS POSITION THE HOOK.

THEN A PRESS RAMS IT INTO THE WOOD

4/10 OF AN INCH DEEP.

THE HOOK HAS SCREWLIKE THREADS AT THE BASE

WHICH GRAB AND LOCK INTO THE SURROUNDING WOOD.

FOR CERTAIN MODELS,

THE FACTORY STAINS OR PAINTS THE WOOD PRIOR TO VARNISHING IT.

AFTER ALL, MANY PEOPLE LIKE THEIR CLOTHES HANGERS

TO MAKE A FASHION STATEMENT, TOO.

Narrator: AN ERUPTING VOLCANO

LED TO THE INVENTION OF STONE WOOL INSULATION

A CENTURY AND A HALF AGO.

IT WAS OBSERVED THAT VOLCANIC LAVA

COULD BE WHIPPED INTO WOOLLY TUFTS BY PREVAILING WINDS.

SOON, THIS WAS BEING REPLICATED IN FACTORIES

TO PRODUCE STONE WOOL FOR INSULATION.

SHAPED INTO BATTS,

STONE WOOL INSULATION CAN BE TUCKED SNUGLY

BETWEEN THE STUDS OF A FRAMED WALL.

IT ACTS AS BOTH A THERMAL AND ACOUSTIC INSULATOR.

AND HERE'S THE SOUNDPROOFING PROOF.

IN THIS DEMONSTRATION,

AN ACTIVATED ALARM GOES INTO A BOX LINED WITH STONE WOOL.

WHEN THE LID IS CLOSED, THE SOUND IS CONTAINED.

AND WHEN IT'S LIFTED AGAIN, THE ANNOYING SOUND IS BACK.

THEY MAKE STONE WOOL FROM BASALT ROCK AND SLAG

RECYCLED FROM THE STEEL INDUSTRY.

THE PROCESS IS FUELED BY COKE, WHICH IS A FORM OF COAL.

BASALT ROCK IS SOLIDIFIED LAVA FORMED

WHEN ROCK MELTS UNDERGROUND AND THEN QUICKLY COOLS.

AFTER THE ROCK HAS BEEN PARTIALLY CRUSHED AT THE QUARRY,

A LOADER SCOOPS IT ONTO A SCREEN

TO SEPARATE THE BIGGER PIECES FROM THE FINE PARTICLES.

THE PARTICLES WILL BE PROCESSED INTO BRIQUETTES,

WHICH CAN BE USED IN THE PRODUCTION OF STONE WOOL,

ALONG WITH THE BIGGER PIECES OF ROCK.

THE ROCK AND BRIQUETTES, ALONG WITH THE STEEL SLAG,

MELT INTO LAVA IN A FURNACE.

TEMPERATURES REACH 2,700 DEGREES FAHRENHEIT --

AS HOT AS A VOLCANO.

A SPINNING MACHINE WHIPS THE LAVA

INTO THIN STANDS OF STONE WOOL

IN A PROCESS THAT'S LIKE MAKING COTTON CANDY.

THE STRANDS FORM TUFTS,

AND A LITTLE BINDING SOLUTION HOLDS THEM TOGETHER.

A SPRAY OF OIL ADDS WATER REPELLENCE.

NOW A FLEECY WEB,

THE STONE WOOL RIDES A CONVEYOR TO THE FACTORY'S UPPER LEVEL,

WHERE IT SPILLS INTO A HUGE PENDULUM DEVICE.

THE PENDULUM SWINGS TO AND FRO

TO LAYER THE STONE WOOL IN A ZIGZAG PATTERN.

THE NUMBER OF LAYERS VARIES,

DEPENDING ON THE KIND OF INSULATION BEING MADE.

THE NOW-LAYERED STONE WOOL

TRAVELS BETWEEN ROLLERS THAT COMPRESS IT SUBSTANTIALLY,

ADDING DENSITY TO THE WOOL.

AUTOMATED PUSHERS TUCK IN THE PACK ON EACH SIDE

AS THE WOOL ENTERS A LONG OVEN.

THE HEAT CURES THE BINDER APPLIED EARLIER,

ALLOWING THE COMPRESSED FIBERS TO HOLD THEIR SHAPE.

THE NOW-TIGHTER PACK EXITS THROUGH A COOLING ZONE

AND TRAVELS UNDER A ROLLER

WHICH SQUEEZES IT TO MAKE THE FIBERS MORE FLEXIBLE.

CIRCULAR BLADES THEN SLICE

THE MOVING MASS OF STONE WOOL LENGTHWISE.

A BRANDING TOOL BURNS THE R-VALUE AND COMPANY NAME

ONTO THE SURFACE OF THE INSULATION AS IT MOVES FORWARD.

ROBOTIC ARMS SWING BACK AND FORTH

TO SLICE THE INSULATION TO ITS FINAL DIMENSIONS.

INSTEAD OF SHARP, STEEL BLADES,

THESE ROBOTS USE HIGH-PRESSURE WATER JETS TO MAKE THEIR CUTS.

THE JETS DO A PRECISE JOB

WITHOUT GENERATING DUST OR WASTE,

AND THE STONE WOOL DOESN'T ABSORB THE WATER FROM THE JETS.

THE SHEER DENSITY OF THE WOOL MAKES IT MOISTURE-RESISTANT,

ALONG WITH THE OIL ADDED TO THE FIBERS DURING SPINNING.

TO DEMONSTRATE STONE WOOL'S WATER-REPELLENT QUALITIES,

THEY POUR WATER DIRECTLY ONTO THE SURFACE.

THERE'S NO ABSORPTION. THE WATER JUST RUNS OFF.

IN THIS ROUTINE TEST,

A WORKER TORCHES THE WOOL, AND IT DOESN'T CATCH FIRE.

STONE WOOL CAN WITHSTAND TEMPERATURES

OF ALMOST 2,200 DEGREES FAHRENHEIT

DUE TO ITS NATURAL PROPERTIES.

IT'S EVEN COOL TO THE TOUCH ON THE OTHER SIDE.

ONCE IT'S PASSED SEVERAL QUALITY-CONTROL TESTS,

THE INSULATION HEADS FOR THE PACKAGING LINE.

GRIPPERS PULL ON A ROLL OF PLASTIC TUBE PACKAGING,

AND HOT JAWS CUT AND SEAL ONE END TO FORM AN OPEN BAG.

MECHANICAL FINGERS HOLD THE OTHER END OPEN

AS MACHINERY SLIDES IT OVER A METAL SPOUT.

A COMPRESSED STACK OF INSULATION IS PUSHED INTO THE SPOUT.

THE SPOUT EXPANDS,

AND THE INSULATION IS RELEASED INTO THE BAG.

THE SPOUT THEN RETRACTS, AND THE PROCESS IS REPEATED.

MACHINERY HEAT-SEALS THE OPEN END.

FROM A PILE OF BASALT ROCK AND RECYCLED STEEL SLAG

TO A BAG FULL OF INSULATION,

IT'S BEEN A WILD AND WOOLLY RIDE.
