Broom: From Traditional Craft to Modern Production


Background

For centuries, brooms have been the unsung hero of household and workplace cleanliness. While most people recognize the common plastic broom, the true heritage lies in the durable, natural‑bristle broomcorn broom—crafted from the stiff stalks of Sorghum vulgare (broomcom) or the yucca‑derived sotol fiber. Unlike its plastic counterparts, which merely redistribute dust, broomcorn brooms absorb, resist moisture, and endure heavy use, making them the premium choice for professional and home use alike.

Broomcom is a variant of the upland sorghum, cultivated for its rigid stems that grow 2–8 ft (0.61–2.4 m). Mexico supplies the majority of the stalks and sotol fiber used in U.S. broom production, reflecting the crop’s resilience in hot, arid climates and its high carbohydrate yield for both human cereals and animal feed.

The manufacturing of broomcorn brooms remains largely artisanal. A single operator oversees the entire process on a dedicated machine, a practice that has changed little since the mid‑20th century. Despite this hand‑crafted heritage, the industry has faced modern pressures, notably from the 1994 NAFTA tariff removal, which introduced cheaper Mexican imports and reduced domestic production to roughly fifteen U.S. manufacturers.

Beyond cleaning, brooms carry cultural significance. The “jumping the broom” ritual, rooted in enslaved African‑American weddings, has evolved into a symbolic act at contemporary ceremonies, with custom‑handmade brooms serving as meaningful centerpieces.

History

Early brooms consisted of bundled, dried branches and brush, often tied with yarn or fabric. In the late 18th century, Levi Dickinson of Hadley, Massachusetts, is credited with creating the first broomcom broom for his wife, though the Shakers are widely recognized for standardizing the flat broom design in 1798. Their innovations—wire binding, treadle machinery, and seed‑removal techniques—enabled production rates of up to twenty‑two brooms per person per day, a remarkable feat for the era.

Today, electrical power drives the machinery, yet the fundamental hand‑crafted method persists. Each broom is uniquely fashioned by its maker, ensuring quality control at the individual level.

Raw Materials

Broomcorn – shipped in large bales, sorted by length and color (brown‑red grades are typically relegated to the broom’s interior). • Sotol fiber – a cost‑effective yucca fiber used in cheaper broomcorn brooms. • White 18‑gauge wire – secures broomcorn to the handle. • Wooden handles – usually ramin or hardwood; occasionally imported ramin for its density and grain. • Thick twine – used in the final sewing process to flatten and secure the broom. • Water – essential for softening the broomcorn before shaping.

The Manufacturing Process

  1. Incoming bales (≈120 lb/54 kg) are submerged in water for 10 seconds, then lifted onto racks for drying.
  2. Operators separate the wet bundles, distributing them to their stations.
  3. A wire is inserted through a pre‑drilled hole in the wooden handle, anchoring the central, low‑grade bundle.
  4. Higher‑grade side bundles are wrapped around the core with tinned wire, forming the broom’s shoulders.
  5. The operator trims the excess grass with a knife, preparing the base for the outermost layer.
  6. The premium hurl layer is laid over the core and secured with the same wire, completing the broom’s exterior.
  7. During the “run‑down” step, the wire is tightened and the broom’s tip is nailed to the handle, ensuring structural integrity.
  8. Fully assembled brooms are dried in a thermostatically controlled chamber for 5–6 hours until moisture is fully evaporated.
  9. Seed removal (seeding) is performed by cylinders that strip loose seeds from the broomcorn.
  10. Final flatness is achieved by running the broom through a heavy‑du‑ty sewing machine with dual needles and thick twine, taking roughly 45 seconds per broom.
  11. The finished brooms are trimmed, packaged, and dispatched for distribution.

Quality Control

Quality starts with the grading of broomcorn by length and color. Brown‑red broomcorn, considered inferior, is reserved for the broom’s interior to maintain a polished appearance. Each machine is meticulously maintained, and the operator—who works the entire cycle—serves as the primary quality gatekeeper, ready to discard any subpar product before it reaches consumers.

Byproducts and Waste

Processing generates minimal waste. Shorter grasses and seeds are promptly removed; these byproducts, while fire‑hazardous, are disposed of quickly to mitigate risk. Broomcorn’s low flammability once ignited makes fire control a critical safety consideration.

The Future

While traditional broomcorn brooms remain largely unchanged, modern alternatives include synthetic fibers, polypropylene bristles, and ergonomic rubber handles. E‑commerce has also expanded access, allowing consumers to order high‑quality broomcorn brooms worldwide.
