Solve pollution. Save lives. Protect the planet.

Pure Earth Mexico

Pure Earth developed high-impact country programs to eradicate the use of lead glazes in Mexican pottery. We work closely with potter communities, restaurateurs, companies, and opinion leaders to protect this ancient tradition and find sustainable solutions for lead-poisoning prevention in Mexico.

The Challenge

Lead poisoning in Mexico is a major problem. It affects many aspects of society. According to the 2019 National Health Study, ENSANUT, almost 20 percent of children have lead levels in blood at dangerous levels. In some states close to 50 percent are affected. It is the poor who suffer the most. Lead at these levels causes permanent brain damage in babies.

The implications are extraordinary: a loss of intelligence (3 to 5 IQ points), a loss of educational attainment on average of about one year; an increase in cardiovascular disease and substantially more deaths from stroke and heart attack, an increase in kidney disease, and an increase in violent crime.

Leaded Pottery

In Mexico, the main source of lead poisoning is the glaze used in artisanal Mexican pottery. These pots, an iconic Mexican tradition, are usually made in small, family-run kilns, often by indigenous communities. The lead is used in the glaze to prevent liquids from leaching and to give color and shine. Lead poisoning is a serious problem in the homes of these artisans as well as their customers, where very high levels of lead in soil and blood can be found.

The solution is straightforward. They can transition to using lead-free glaze, which is similarly priced and has a similar appearance. Training is needed to change to that glaze, as there are important differences in technique, and changes in glaze sourcing. Some kilns may need to be upgraded, and the areas surrounding the converted kilns need to be remediated.

There are around 10,000 small and medium-sized industries making Mexican pottery. Converting them to be lead-free requires a concerted effort from many sectors.

Mexico's Headlines


Pure Earth continues to develop sustainable solutions to prevent lead poisoning by working directly in rural pottery communities. To ensure the highest impact of our work, every year we organize a meeting of potters to invite new members to our programs, exchange technical knowledge and strengthen pottery communities’ ties.


The four-month exhibit “Lead-Free Traditional Pottery in Morelos” was inaugurated with the participation of high-ranking Morelos tourism officials, international allies, artisans, media, and the Pure Earth team. This exhibit showcases the work of the “Círculo de Mujeres Hechas de Barro” artisans’ program for four months.
The exhibit’s message will be reinforced with two on-site Lead-free pottery innovations conferences.

2023 Earth Day Event
2023 Earth Day Event

Within the framework of International Earth Day and in the context of the international campaign #InvestInPureEarth, Pure Earth Mexico held an event to strengthen alliances that seek to prevent lead poisoning in Mexico, eliminating the use of lead glazes in Mexican pottery and improve development opportunities for children.

Tabasco Fair

Pure Earth Mexico participated in Tabasco Fair 2023 to showcase the Círculo de Mujeres lead-free pottery, with the participation of high-ranking state officials, foundations, academia, and the general public. This activity is the first step to having our pottery community methodology developed by third parties in this state.

Country Programs

Barro Aprobado
Barro Aprobado

Barro Aprobado is a Pure Earth México program to promote lead-free production in pottery communities. A program aimed to reduce lead blood levels in Mexico’s population, which in turn promotes the preservation of traditional pottery.

Circle of Women
Circle of Women

Círculo de Mujeres Hechas de Barro is a Pure Earth México program that supports groups of women to undertake the production of lead-free pottery. The program strengthens the sense of community, technical training, and business knowledge.

Lead-Free Food Alliance
Lead-Free Food Alliance

The Lead-Free Food Alliance unites companies, academic institutions, government, restaurants, commerce, and civil society organizations to join Mexico’s lead-solutions efforts and promote the use of lead-free pottery. This Alliance is the only of its kind that represents all Mexican pottery stakeholders at various levels.

Awareness Campaign #SinPlomoEnlaMesa/#Lead-FreeTable

Pure Earth Mexico launches the first edition of the annual campaign #SinPlomoEnLaMesa to raise awareness of the importance of lead-poisoning prevention actions and the benefits of lead-free pottery.
Over ten corporate allies supported the campaign with in-kind donations and lead-poisoning awareness messages to their clientele.

Featured Stories

Hope Begins with Lead Solutions



Education begins with lead solutions

Having available schools and effective learning programs will not result in quality education if children are unable to learn due to cognitive impairment produced by Lead Poisoning. Studies show that lead levels in blood of more than 5 micrograms per deciliter are associated to an IQ loss of more than 5 points.


Development begins with lead solutions

Lead poisoning is passed from one generation to the next. If toxic lead levels continue in the environment, families will continue to suffer from lead poisoning-related problems. This will continue to affect their ability to develop and reach their full potential, thus perpetuating the poverty cycle. Lead poisoning affects lives and has an impact on the national economy.


Protection begins with lead solutions

Lead poisoning in children can produce behavioral disorders that are often related to, sometimes aggressive, disciplinary measures.  This is more common in low-income communities where lead poisoning is more frequent, and lack of health services prevent from proper diagnosis and treatment.


Helath begins with lead solutions

Premature brain aging, anemia, kidney damage, cardiovascular disease, and harm to pregnant women and developing children are health issues related to Lead Poisoning. Health services that do not test blood for lead poisoning are providing inadequate treatment that is costly and ineffective.


Advocacy begins with lead solutions awareness

Lead Poisoning is still an invisible problem in many developing communities. The lack of awareness and advocacy result in limited prevention programs, low solutions reinforcement, restricted political actions, and limited support. Without a strong common voice, that spurs immediate and effective action and sustainable measures, lead poisoning will continue to affect thousands of people. The key is better prevention to reduce the need of correction. The key is to enforce existing law to assess further legislation. The key is public and private engagement.


Is not about using less, is about using better. The key to sustainable transformation

Only 1% of all pottery in Mexico is lead-free! There are technical, cultural, and commercial issues that need to be considered for an effective solution. Pure Earth has over 15 years of experience developing a sustainable transformation.


Partners and Donors

Clarios Kids

A new generation comes together for Lead Solutions

Children from pottery communities tell children from Clarios personnel about the pottery process and the importance of using lead-free pottery.

Lead poisoning affects the development and health of 800 million children worldwide. In Mexico, the main source of contamination comes from food prepared in clay pots enameled with lead. For this reason, Pure Earth México and Clarios -during the Clarios Kids event this past August 5, achieved a bridge of communication for children where girls and boys from pottery communities told how traditional Mexican pottery is made and the actions that are taken to achieve lead-free products. Thus, new generations join this cause.

Sofía, Carolina, Edgar, and Samuel told step by step how pottery works in their family. They invited them to their homes and their workshops where they showed with great joy how they play, have fun, and express themselves. In addition, they told us how important it is for them to protect the tradition and at the same time prevent lead from reaching other children.
Events like this one help more people, especially girls and boys, learn not only about the problems caused by lead poisoning but also about the solution that has been taking place in Mexico for 15 years. At the same time, they learn to value traditional Mexican pottery which is the livelihood of thousands of families.
