Legacy lead sources. Mostly not pressing, still interesting.
These are the exposure pathways I deliberately kept off the 187-cases page. They show up in the historical record but rarely impact a modern home today, phase-outs, bans, and changing manufacturing have taken them off the table for current cases. Worth knowing for context, occasional inheritance, and the few situations where they still matter.
Why this exists as a separate page: someone buying a Fluoro-Spec kit today does not need to test their wine-bottle foil capsules from the 1980s or worry about Roman aqueducts. But these sources do come up in conversation, in inherited collections, in old-house renovations, and as background to understanding why lead-poisoning prevention is the legacy field it is. So, here they are, separated cleanly.
Recently phased out (last 30 years)
These were active risks in the 1980s, 90s, or early 2000s. Bans, manufacturing changes, or market pressure have largely removed them from current circulation, though residual cases still exist in inherited goods or specific specialty contexts.

Lead roof sheeting on heritage cathedrals & civic buildings
Old cathedrals, town halls, and 19th-century civic architecture used sheet lead for roofs. Mostly EU. Real if you live in a converted heritage building or work on one; otherwise: zero contact.
Mostly pre-1900 construction; restoration projects ongoing
Source #24 (originally listed)
Painted cribs, cots & nursery furniture (pre-1980)
Crib paint pre-1978 (US) / pre-1980 (AU) routinely contained lead. Today's factory-made cribs do not. Vintage / heirloom / hand-me-down cribs in a contemporary nursery are the residual case, but the modern volume is small.
Phased out 1978 (US lead-paint ban); residual in inherited furniture
Source #84 (originally listed)
Canned food with lead-soldered seams
Until ~1995, three-piece tinned cans were soldered with leaded solder along the side seam. Lead leached into acidic foods (tomato, fruit). Modern cans are welded or stamped two-piece. Only relevant for collectible / vintage canned imports.
US-banned 1995; some imports lagged through the 2000s
Source #92 (originally listed)
Wine stored under lead-foil capsules
Wine bottles used to be sealed with a lead-foil capsule over the cork. Pouring wine over the capsule could pick up lead. Switched to tin or PVC foils in the 1990s. Real for wine cellars with bottles older than that.
EU-banned 1993; producers had switched globally by mid-1990s
Source #134 (originally listed)
Progressive hair dye (Grecian Formula, Just For Men)
Lead acetate was the active ingredient in "men's color-restoring" hair products for decades. It deposited lead-sulfide pigment in the hair. FDA banned the formulation in 2018 after public-health pressure. Reformulated alternatives now use bismuth.
US FDA ban: October 2018

Car body restoration "lead loading"
Pre-1980s autobody work used pure lead bars to fill seams and dents (called "leading-in"). Replaced by polyester body filler ("Bondo") in the 70s-80s. Real for hot-rod restoration shops and people grinding old body panels; otherwise irrelevant.
Mostly phased out by 1985; persists in classic-car restoration
Source #166 (originally listed)
Decorative candles with lead-cored wicks
Some imported decorative candles used a thin lead wire down the center of the wick to keep it standing upright. Burning aerosolized lead into the room. Voluntary phase-out in the US 1974, formally banned 2003.
US-banned 2003; pre-2003 imports may still exist
Source #168 (originally listed)
Leaded foil on wine bottles (the foil itself)
Distinct from the seal hazard above, the actual foil sleeve was historically pure lead pigment foil. Now tin or PVC. Aging cellar bottles are the only residual case.
Phased out 1990s alongside #4 above
Source #175 (originally listed)
Lead arsenate pesticide residue in old orchard soil
Apple, pear, and cherry orchards sprayed lead arsenate pesticide widely from 1900 to the 1950s. Soil retains the lead. Real if you live on / garden on a former orchard property, soil test only confirms.
Used 1900-1950s; residue persists in soil indefinitely
Source #176 (originally listed)
Lead chromate dyed seed (historic agricultural)
Yellow lead chromate was historically used as a seed dye to mark treated seed for planting. Replaced with safer dyes in the late 20th century. Mostly relevant for soil legacy on old farm fields.
Historic; replaced by mid-20th century
Source #188 (originally listed)
Church bells (bronze with lead inclusions)
Bell-bronze alloy traditionally included a small percentage of lead. Bell ringers, and historically, children allowed to play in bell towers, had unique exposure. A genuine historical curiosity, almost zero modern public-health impact.
Centuries-old practice; modern bells less affected but the alloy persists
Source #191 (originally listed)
Brass sculpture & bronze art (cast)
Cast bronze sculpture historically used leaded alloys for casting flow. Modern foundries have reduced lead content for safety reasons. Sculptors and conservators handle this; museumgoers don't.
Historic art-bronze tradition; modern alloys are mostly low-lead
Source #199 (originally listed)
Old wrought-iron fencing paint
Heritage wrought-iron, Victorian-era fencing, gates, balconies, was protective-coated with leaded paints. Not a child contact issue (high up, not chewed) but a renovation/restoration concern when sanding or stripping.
Pre-1978 fencing paint formulations
Deep history (medieval to mid-20th century)
These are the why behind everything we test for today. Not actionable for a modern home, but the historical mass-poisoning events that shaped the current regulatory framework. Useful background for anyone going deep on the topic.
Lead pipes in Roman aqueducts
The Latin plumbum for lead is the root of "plumbing." Roman engineers piped water through lead aqueducts for centuries. Some historians attribute aristocratic-class lead poisoning to these pipes (debated; calcium-carbonate scale may have buffered most of it). The word stuck even after the metal got phased out.
Roman Empire (~200 BC–AD 400)
Lead acetate ("sugar of lead") as wine sweetener
From Roman times through the 19th century, vintners added lead acetate to wine to sweeten it and preserve it. The compound tastes sweet (hence the name). Mass poisonings traced to this practice are documented in historical records, most famously the "Devon colic" outbreaks of 17th-18th century England traced to cider made in lead-lined cider presses.
Antiquity to ~1900 (regional bans starting earlier)
Venetian ceruse (lead carbonate face powder)
White-lead face powder was the cosmetic standard from the Renaissance through the Victorian era. Used to achieve a pale "noble" complexion. Caused widespread chronic lead poisoning among elite women. Replaced by zinc-oxide and titanium-dioxide formulations only in the 20th century.
1500s–1900s; persisted in some markets later
Tetraethyl lead (TEL) in gasoline
Patented 1921 by Thomas Midgley as an "anti-knock" additive to gasoline. Phased out US 1973-1996, AU 2002, globally 2021 (Algeria was the last country). The atmospheric lead loading from leaded gas is the single largest mass-poisoning event in human history. Children born during peak years (1960s-1980s) carry a measurable cohort effect on IQ. Soil along old highways still has the legacy.
1923 introduction; US-banned 1996 (road fuel); global ban 2021
White lead pigment in oil paint (pre-1900 fine art)
White lead (basic lead carbonate) was the primary white pigment for oil painters from antiquity through the 19th century. Old Masters worked with it directly. Modern art conservation involves significant lead exposure for restoration teams handling 16th–19th century canvases.
Antiquity through ~1900; replaced by zinc and titanium whites
Lead-glazed Roman & medieval pottery
Pre-industrial European pottery used lead-frit glazes for low-temperature ceramic finishes. Famously implicated in chronic poisoning among potters and consumers. Modern food-contact ceramics in the EU/US have lead leach limits; the historical baseline is what made those limits necessary.
Roman through ~1700s; legacy effects in collected antiques
Lead in printer's type & typesetting
From Gutenberg to the late 20th century, movable type was cast from lead-tin-antimony alloy. Linotype machines melted and cast lead lines for newspapers, the typesetters had measurable occupational exposure. Computerized typesetting ended the practice in the 1980s.
1450s–1980s; ended with desktop publishing
