Pearl Ash (Potassium Carbonate)

Key Features & Benefits:

• High-purity potassium carbonate (K₂CO₃), also known as pearl ash.

• Acts as a solid potash flux source: when used in glazes or ceramic bodies, provides K₂O without introducing unwanted oxides.

• White, hygroscopic solid, highly soluble in water (≈ 110 g per 100 mL at 20 °C) making it efficient for dissolving & dispersing.

• Large format 50 lb (≈ 22.7 kg) bag offers economies of scale for studios, manufacturing, or bulk users.

• Versatile industrial/creative uses: ceramics, glass, glazing, chemical intermediates, and speciality manufacturing.

Typical Applications:

• Ceramics & Glazing: Use in mid-to-high temperature glazes as a potash flux; yields distinctive colour effects (e.g., copper + high potash = green-yellow tones).

• Glass & Frit Manufacturing: A direct source of K₂O, useful when other oxides must be avoided.

• Chemical Feedstock: Employed where a highly alkaline potassium salt is required.

• Traditional Food/Leavening Contexts: Historically used as a leavening agent (pear-ash in baked goods) though this product is intended for industrial/technical use-cases.

Technical & Handling Info:

• Chemical Formula: K₂CO₃.

• Appearance: White crystalline/hygroscopic solid.

• Storage: Keep tightly sealed, dry environment — material absorbs moisture from air (hygroscopic) which may cause clumping.

• Safety: Handle with appropriate PPE (gloves, eye protection). Due to its alkaline nature, avoid skin/eye contact and store away from incompatible acids.

• Packaging: Supplied in a robust bulk-bag appropriate for 50 lb weight; ideal for studio backstock or batch production.

Why Choose This Product?

For the serious ceramicist, glass-fabricator or chemical-processing professional: this bulk format provides a cost-effective way to access high purity potash flux/alkali in the scale you need. No compromise in quality, and excellent flexibility for custom formulae, glaze recipes or industrial chemical needs.

Use & Application Tips (Staff-College style “Order of Battle”):

1. Recon & Preparation: Confirm your substrate (glaze base, clay body or chemical mix) tolerates a highly alkaline addition.

2. Deployment: Incorporate powder in your batch with caution — mix dry first, then add water or other liquids as required. Ensure full dissolution if you intend to use the solution form.

3. Monitoring: Because K₂CO₃ is very soluble and active, monitor your colour response, melt behaviour and compatibility. For glaze use: a potash-rich glaze will melt differently than a sodium-rich one.

4. After-Action Maintenance: Store remaining material in a sealed container in a low-humidity environment; label clearly for “technical use – not food grade” unless documented otherwise.

5. Contingency: Always keep a small sample for reference. When scaling up, use consistent testing to ensure batch-to-batch repeatability.
