The Hidden Problem Most Families Face After Cremation
When families choose cremation, they often discover an uncomfortable truth that no one prepared them for. The cremated remains they receive can feel impossible to live with comfortably. These ashes create barriers to connection rather than bringing families closer to their departed loved ones.
Cremated remains are messy and spill easily, contain visible bone fragments that can be distressing to see, and blow away unpredictably when families attempt outdoor scattering. Many families find themselves storing these remains in closets, basements, or garages simply because they feel too anxious or uncomfortable to keep them in their living spaces.
This hidden crisis affects approximately 75 million Americans who currently live with cremated remains stored away from daily life. Families desperately want to feel close to their departed loved ones, but conventional ashes often create anxiety rather than comfort.
Reflections on love, loss, and the ways we carry them.
In my years as a grief counselor, I’ve witnessed a quiet, often unspoken discomfort among families after cremation. They bring home an urn expecting peace, only to find unease. The ashes: powdery, uneven, sometimes containing bone fragments, feel too fragile to touch, too sacred to store away. So the urn is placed in a closet or under the stairs, waiting for the right moment that never comes.
One family I worked with kept their son’s ashes in a paper bag inside a cabinet for three years. They told me, “We love him too much to scatter him, but we can’t bear to open the urn.” That conflict between love and discomfort, is often one of grief’s hidden burdens
This is why the innovation behind solidified remains has moved me deeply. The process transforms cremated remains into smooth, stones that are solid, clean, and enduring. Each stone is unique, as if shaped by the person’s own story. When families hold them, they often say the same thing: “I can finally breathe.”
Solidified remains offer something ashes rarely can. They offer comfort through touch, and allow families to hold, share, and display their loved one’s memory in a form that feels both beautiful and permanent.
Grief will always ache, but when we can cradle memory in our hands, it softens the sorrow. And sometimes, that simple act - the weight of love made tangible, is what helps a family begin to heal.

What Are Solidified Remains?
Solidified remains represent an entirely new category in death care. Rather than being a product that uses ashes, this process creates a complete alternative form of remains. When families choose cremation, they can now choose between receiving cremated remains or solidified remains.
This scientific approach transforms the vast majority of cremated remains into smooth, stone-like forms that families can hold, share, and cherish. The resulting collection typically consists of 40-80 individual stones, each unique in size, shape, and natural coloring.
The Four-Stage Scientific Process
| Stage | Process | Scientific Focus | Timeline |
|---|---|---|---|
| Refinement | Remove contaminants, refine ash into fine powder | Materials purification and preparation | Weeks 1-2 |
| Formation | Add glass-based binder, create clay-like material | Binding chemistry and formability | Weeks 3-4 |
| Solidification | Controlled kiln heating for permanent hardness | High-temperature ceramic processing | Weeks 5-7 |
| Finishing | Cleaning, polishing, and quality control | Surface treatment and quality assurance | Weeks 8-10 |
The solidification process begins with careful refinement of the cremated remains. Trained technicians remove any foreign contaminants, such as medical implants, surgical staples, or screws, that may remain after cremation. The granular ash material is then gently refined into a fine, consistent powder. This refinement stage ensures the highest quality foundation for the transformation process.
During the formation stage, a small amount of glass-based binder is carefully added to the refined ash powder. This creates a clay-like material that can be formed into individual stones. The binding agent represents only a minimal addition to the original remains, allowing the vast majority of the cremated material to be preserved in the final stones. The formation process draws from multiple scientific disciplines, including pharmaceutical manufacturing, mineral processing, and ceramic production techniques.
The formed stones are carefully placed into specialized kilns for the solidification stage. This controlled heating process gives the solidified remains their ceramic-like hardness and permanence. The heating cycle has been precisely developed to ensure optimal transformation while maintaining the integrity of the original material. The temperature and timing protocols used in this stage are the result of extensive research and development conducted in partnership with materials scientists at Los Alamos National Laboratory.
The final stage involves careful cleaning and polishing of each stone. Quality control specialists examine every piece to ensure it meets the scientific and aesthetic standards families deserve. The finished solidified remains feel similar to natural river stones, with a clean, permanent surface that will not dissolve in water or scratch with fingernails. Each completed stone collection is carefully packaged and prepared for return to the family.

The Science Behind Los Alamos Partnership
The development of solidified remains technology involved collaboration with material scientists at Los Alamos National Laboratory, one of the world's leading research institutions. This partnership brought advanced materials science expertise to the challenge of creating a dignified, permanent form of remains.
Los Alamos scientists contributed their knowledge of high-temperature processing, materials composition, and quality control methodologies. Their involvement ensures that the solidification process meets rigorous scientific standards while respecting the emotional significance of the materials being transformed.
An environmental impact study conducted in conjunction with Los Alamos National Laboratory found that scattering solidified remains has a negligible environmental impact, especially compared to traditional cremated remains, which can substantially affect soil water and soil chemistry.
Understanding the Transformation Results
What Families Receive
Each solidification process results in a unique collection of stones reflecting the individual characteristics of the person or pet being honored. Families typically receive between 40 and 80 stones, ranging from thumbnail to palm-sized, each with its own natural shape, texture, and color.
The volume of solidified remains returned approximates the volume of cremated remains received. For example, eight cups of conventional cremated remains will return approximately eight cups of solidified remains in stone form.
The Unique Nature of Each Collection
One of the most remarkable aspects of the solidification process is that each stone emerges differently. The natural variations in cremated remains, combined with the scientific transformation process, create stones with unique characteristics that reflect the individual being honored.
No two collections are identical, and the process cannot be customized to create specific shapes or colors. This natural variation ensures that each family receives stones that are truly unique to their loved one.
Quality Assurance and Process Integrity
Every order receives completely individual processing to maintain the highest standards of integrity and respect. Parting Stone uses individualized equipment for each step of the process, ensuring that remains are never mingled or combined with other families' materials. A single trained technician handles each family's remains throughout the entire transformation process, maintaining continuity and accountability from beginning to end.
The comprehensive quality assurance approach includes:
- Individual order processing with dedicated equipment for each family
- Single technician continuity throughout the entire 8-10 week process
- Email notifications at key stages to keep families informed
- Detailed documentation and tracking for complete transparency
- Chain of custody protocols ensuring integrity from receipt to delivery
- Final quality control inspection before return to families
This systematic approach helps build confidence and trust during what can be an emotionally challenging time. Families can have complete confidence that their loved one receives individual attention and respectful treatment throughout the scientific transformation process.
The Environmental Science
Sustainable Transformation
The solidification process produces no harsh chemicals or harmful emissions during transformation. While the kiln heating does require energy, the overall environmental impact remains minimal compared to many traditional memorial options.
Long-term Durability
The ceramic-like properties of solidified remains ensure they will maintain their integrity indefinitely. Unlike traditional cremated remains, which can be affected by moisture, wind, and environmental factors, solidified remains offer permanent stability.
This durability means families can create lasting memorials, whether they choose to keep stones together, share them among family members, or place them in meaningful outdoor locations.
Why Scientific Approach Matters
Evidence-Based Development
The development of solidified remains technology represents years of scientific research and testing. This evidence-based approach ensures that families receive a reliable, high-quality transformation that honors their loved one with dignity and respect.
The scientific methodology addresses common concerns about memorial options by providing a solution that is both emotionally meaningful and technically sound.
