High-purity 99.95% magnesium ribbon (lab grade) for chemistry teaching, combustion demonstrations, thermite prep, activity-series experiments, and industrial laboratory use. Consistent bright-white flame + predictable burn rate = reproducible classroom results every time. 25g roll ≈ 70 feet (21.3 m) usable ribbon at 4mm × 0.2mm cross-section. Individual roll to 100-roll bulk pack for teaching sets, contract lab supply, and institutional procurement. $19.99 per single roll to $1,499.99 for 100-roll case.

Safety notice: Magnesium ribbon ignites at ~473°C + burns at 3,100°C with intense UV emission. Always use welding-grade UV eye protection (NOT standard safety glasses) — direct viewing of magnesium flame causes photokeratitis (welder's flash). Never handle burning ribbon with bare fingers. Store in dry sealed container away from moisture (moisture accelerates surface oxidation + reduces ignition reliability). Follow all school + OSHA lab safety protocols. This product is sold for lab / educational / research use only.

Applications

  • High school + college chemistry demonstrations — the classic "magnesium combustion" demo showing bright-white flame, MgO product formation, exothermic reaction stoichiometry
  • Activity series experiments — reactivity of Mg with dilute acids (HCl, H₂SO₄), water (steam), oxygen — foundational undergraduate lab
  • Grignard reagent prep — organic chemistry: Mg metal reacting with alkyl halides in dry ether to form Grignard reagents (organomagnesium compounds)
  • Thermite reaction preparation — magnesium ribbon as the ignition fuse for iron oxide + aluminum thermite demos (advanced supervised chemistry)
  • Emission spectroscopy demonstrations — burning Mg emits characteristic UV + visible spectrum for teaching atomic emission
  • Rocket + pyrotechnic education — supervised amateur rocketry, safe fireworks chemistry teaching (with appropriate permits)
  • Metallurgy + materials science labs — reactive metal handling training
  • Emergency + survival kit assembly — magnesium ribbon as fire-starter component in survival preparedness kits

Specifications

Purity 99.95% Mg (high-purity lab grade — trace impurities primarily Al, Si, Fe, Ca)

Roll weight ~25 g per roll
Roll length ~70 feet (21.3 meters) per roll
Ribbon width 4 mm (5/32")
Ribbon thickness 0.2 mm
Ignition temperature ~473°C (883°F)
Combustion temperature ~3,100°C (5,610°F) — extremely hot
Combustion product Magnesium oxide (MgO) — white powder residue (nitride Mg₃N₂ if burned in nitrogen atmosphere)
Storage Dry, sealed container, away from moisture + acids. Shelf life 5+ years with proper storage.
Shipping Ships as non-hazardous material (magnesium ribbon in metal spools is not classified as flammable solid in shipping quantities under DOT/IATA thresholds)

Educator vs research vs industrial use

Teaching (most common use): Cut 1-3 cm pieces for individual student combustion demos. One 25g roll = 200+ demo pieces at 3cm each = full semester supply for 4-6 chemistry classes.

Research lab (Grignard prep): Cut to specified length per protocol (typically 1-2 g Mg per Grignard synthesis). Store cut ribbon in dry desiccator between uses.

Industrial + pyrotechnic (bulk): 100-roll case = 2.5 kg for pyrotechnic composition, thermite ignition supply, or contract chemistry lab consumable inventory.

Best for

  • High school + college chemistry teachers (essential combustion demo material)
  • University chemistry teaching labs (undergraduate + organic + inorganic curriculum)
  • Research chemistry labs (Grignard reagent prep, activity series)
  • Contract testing + analytical labs
  • Pyrotechnic + fireworks industry (with appropriate ATF permit)
  • Amateur rocketry + survival preparedness (fire-starter component)
  • International science teaching procurement via DDP

Buying for a chemistry department, school district, or industrial supply?

FAQ

Do I need special shipping for magnesium ribbon?

No — for the roll quantities we ship (25g single up to 100-roll 2.5kg case), magnesium ribbon does NOT trigger DOT / IATA flammable-solids shipping restrictions (Class 4.1 threshold is much higher). Ships via standard ground / air freight. For very-bulk institutional orders (>50 kg), contact us for freight arrangement.

Do students need special eye protection to view the burning ribbon?

YES — this is the single most important safety point. Magnesium burns at 3,100°C with intense UV emission that causes photokeratitis (welder's flash) within seconds of direct viewing. Standard safety glasses are NOT adequate. Use welding-grade shade #3 or higher UV-blocking goggles for direct observation, OR position students to view from >2 meters with normal safety glasses (indirect viewing). School lab safety protocols cover this — verify your teacher training materials include the UV warning.

Why 99.95% purity matters for teaching?

Below ~99% purity, trace impurities cause inconsistent ignition (some sections light easily, others require prolonged flame), variable burn rate, and off-color flame (yellowish tint instead of pure white). Lab-grade 99.95% ribbon ignites reliably with a Bunsen burner in 2-3 seconds and burns at predictable rate — reproducible classroom results. Craft-store "magnesium ribbon" is often 90-95% purity and produces frustrated students + failed demos.

How long does an opened roll stay usable?

Properly stored (dry sealed container, away from moisture + acids): 5+ years without meaningful degradation. Signs of degradation: dull grey surface (surface oxidation), reduced ignition reliability, uneven burn. Fresh ribbon has a slight metallic sheen; degraded ribbon looks powdery. If a roll fails to ignite in 5 seconds of Bunsen burner exposure, it's oxidized — replace.

Any restrictions on international shipping?

Some countries classify magnesium ribbon as controlled precursor (particularly for pyrotechnic + explosive concerns). US, Canada, EU, UK, Australia, most Asian markets: no restrictions on small-to-medium quantities for educational/research use. Middle East + some restricted-import jurisdictions may require import permits. Contact us with your destination country for pre-shipment compliance check.
