Why Bone Ash from
Murlin Chemical?
Bone ash has proven to be cost effective and a safety advantage when properly applied. Coatings on steel surfaces provide a safety barrier and a "super plus" in overall housekeeping in casting operations.
Key Benefits
- Bone Ash is cleaner. There is no danger of contamination from impurities such as iron which my be present in other coating material.
- Bone Ash is more efficient coating material. It will cover up to three times the area of other materials.
- Bone Ash works into the pores of the refractory. This provides better coating adhesion than other materials.
- Bone Ash coatings are more resistant to wetting, enabling them to last longer.
Together, these advantages make Bone Ash a dependable solution for aluminum and non-ferrous casting environments where consistency, cleanliness, and performance are critical. By reducing contamination risks, improving surface coverage, and enhancing coating durability, Bone Ash helps manufacturers maintain tighter process control, minimize material waste, and extend the service life of refractory components — ultimately supporting more efficient and cost-effective operations.

Industry Served — Frequently Asked Questions
Answers to common questions about usage, packaging, documentation, and ordering.
What is bone ash used for?
Bone ash is used primarily in the non-ferrous metals industry as a mold release agent, helping protect exposed surfaces and support cleaner casting operations.
Which bone ash grade should I choose?
We recommend Natural Bone Ash for most applications. Our Aluminum Grade Bone Ash is used by customers needing specific traits that are exemplified in this Grade. We are always here to help you decide what is best for your application.
Where is Murlin bone ash applied in casting operations?
We recommend using bone ash anywhere molten metal is present.
What are the main benefits of using bone ash vs other coating materials?
Bone ash is cost effective. Bone ash is a more efficient coating material. It will cover up
to three times the area of other materials. Bone ash appears to work into the pores of the refractory.
This provides better coating adhesion than with other Materials.
Bone ash coatings are more resistant to wetting, enabling
them to last longer.
Bone ash provides a safety advantage over other coating materials as it is non-hazardous and natural.
Bone ash is cleaner. There is no danger of contamination
from impurities such as iron which may be present in other
coating material.
