Discover the Unveiled Truth About Aluminum Herb Grinders: A Comprehensive Guide

Dive into the realm of herb grinders as we unveil the hidden truths surrounding aluminum-based ones. In this comprehensive guide, discover the unique approach we take at MJ Grind, setting our grinders apart. Let's explore the fascinating world of aluminum, its manufacturing intricacies, and the protective innovations that make our grinders a safer and more durable choice.

Aluminum, known for its malleability, is a prevalent material in the realm of herb grinders. A meticulous inspection of your grinder's bottom should reveal tool path markings, indicative of the manufacturing process.

Colored Aluminum Herb Grinders and FDA Regulations

Under the jurisdiction of the Federal Food, Drug, and Cosmetic Act (Chapter VII, section 721), color additives, barring coal tar hair dyes, are subject to FDA vetting before their utilization in food, drugs, cosmetics, or medical devices that interact with human or animal bodies for substantial durations. The subsequent sections shed light on the implications of color additives in FDA-regulated products concerning aluminum herb grinders.   Federal Food, Drug, and Cosmetic Act (Chapter VII, section 721)

Anodized Aluminum Herb Grinders: An Overview

Anodized aluminum herb grinders have become a common sight, however, this ubiquity might not have been if market regulations were stringent. The infusion of coloring pigments during anodization potentially disqualifies the coating for food contact.

Anodizing Processes Unveiled:

1. Soft Anodizing: This process engenders an organic layer atop the material surface, retaining the aluminum's soft nature. If the color on your grinder peels off effortlessly, it's indicative of soft anodization.

2. Hard Anodizing: Contrarily, hard anodizing develops both above and beneath the material surface, enhancing the aluminum's hardness and wear resistance significantly

 

 

Aluminum Grinders: Red Flags

The Dilemma of Wear:

Aluminum grinders are notorious for their rapid wear, a byproduct of aluminum's inherent softness. The wear aggravates with identical material assembly due to heightened friction. As resin accumulates, the grinder's operation becomes arduous, leading to material degradation and surface porosity. This phenomenon, often termed as "shaving," epitomizes the wear process.

Despite the potential for cleaning, the efficacy is questionable. The previously formed pores augment friction, necessitating a smooth surface for optimal function.

You may say, "Yes, but it can be cleaned!" This is true, but not really effective, as the little pores that were created earlier multiply the friction rate. For good friction, a smooth surface is required.

The Color Test:

A simple DIY test can help ascertain the coating type on your colored grinder. Employing a sharp tool, lightly scratch the surface. Easy peeling indicates coloring, while a mix of thin color and aluminum suggests anodization. In case of inconclusive results, either the pressure applied was insufficient, or your grinder boasts a hard anodized coating, albeit a less common occurrence.

In conclusion, our grinders, with their distinctive plastic buffering ring, ensure a safer and more durable usage experience. The encapsulated insights above aim to guide you in making an informed choice while navigating the aluminum herb grinder market.
