Industries Served
Bone ash material for manufacturers who need consistent performance across
metals, ceramics, and industrial processing.
factory Aluminum and Other Non-Ferrous Metals
Improves casting efficiency and finish quality by preventing metal adhesion, extending refractory life, and providing reliable, high-temperature protection—all with a safe, non-toxic formula.
mode_heat Copper Processing
Improves pour quality, minimizes mold erosion, and streamlines cleanup—ensuring a smooth copper finish.
dashboard_2 Cement & Construction Materials
Improves cement performance while reducing environmental impact by increasing early strength, enhancing workability, and minimizing micro-cracks.
stockpot Ceramics Manufacturing
Improves porcelain quality with enhanced translucency, whiteness, and strength, while enabling lower-temperature sintering and greater durability.
humidity_high Glazes & Finishing Materials
Functions as a flux/glass former, affecting glaze opacity and flow—improving movement into detailed areas and adding stiffness at low concentrations.

Reliable Quality for Industrial-Grade Performance
Murlin bone ash is manufactured under controlled conditions to support consistent
performance and reduce variability in demanding manufacturing environments.
Manufactured under carefully controlled conditions and supported by comprehensive quality testing, our Bone Ash delivers outstanding consistency from batch to batch. Every shipment is verified to meet
stringent specifications, ensuring superior purity, predictable performance, and the highest standards of quality for critical manufacturing applications.
Technical Assurance
Technical assurance of bone ash is achieved through tightly controlled raw material sourcing, standardized calcination processes, and rigorous quality testing at every stage of production. Consistent processing conditions ensure stable chemical composition and phase structure, while defined specifications for purity, particle characteristics, and physical performance are verified through routine laboratory analysis.

Frequently Asked Questions
Quick answers to common questions about bone ash grades, applications, ordering, and shipping.
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?
Typically the majority of our customers find that the more cost effective Natural Bone Ash suites their requirements. Our Aluminum Grade Bone Ash is primarily used by customers who require a product that has better packing ability and retains its shape more readily.
Where is Murlin bone ash applied in casting operations?
Bone Ash is applied anywhere molten non-ferrous metals make contact as they do not wet dry bone ash. These include transfer troughs, spouts, pour points, filter boxes, dross skimming containers, damns, furnace tools and permanent casting molds. It can be applied dry, or as a slurry mixing two pounds of bone ash with a gallon of water. A glove or brush is used to apply dry whereas a brush or a spray gun can be used to apply the slurry. It is recommended to use the slurry pretreatment on a warm surface to allow it to dry completely. Subsequent coatings of dry bone ash can be applied without additional slurry pretreatment.
What are the main benefits of using bone ash vs other coating materials?
1) Cost effective
2) Provides a safety barrier and a “super plus” in overall housekeeping in a casting operation
3) Improves the appearance of coated items
4) Reliable leak proof joints and damns
5) It is cleaner, there is no danger of contamination from impurities such as iron which may be present in other coating materials
6) It is a more efficient coating, covering up to 3 times more than other coating materials
7) Murlin Bone Ash works into the pores of the refractory providing better coating adhesion
8) More resistant to wetting enabling coated materials to last longer
Do you provide a Certificate of Analysis (COA)?
Yes. A COA can be provided upon request.
