Oil Soot Hui Ink Stick Classic

Glossy Black Tone You Can Approve Before Production Starts

Oil soot ink sticks disappoint in two ways that matter to professionals. Tone drifts between batches — the glossy black a studio standardized on turns slightly grey or flat in the reorder, and nobody catches it until the work is on paper. And poorly refined soot grinds badly: uneven color saturation in the ink, more effort at the inkstone, and a weaker result from the same calligrapher. Wholesale buyers carry a third risk — ordering thousands of sticks against a tone they have never seen.

Gu Mo Craft Technology produces the Oil Soot Hui Ink Stick Classic from refined oil soot with a natural binder, using a standardized grinding protocol to reach a rich glossy black tone. Every batch is tested for ink density and color consistency before packaging, and tone-matching samples are provided before bulk production — so the buyer approves the exact color on paper, not a supplier's description of it. The stick is polished to a smooth surface finish and produced at a vertically integrated facility that has run controlled soot refining, hand-crafting and quality grading stations since 2011.

What This Ink Stick Is, and Who It Serves

The Oil Soot Hui Ink Stick Classic is a professional-grade oil soot stick with a rich glossy black tone, smooth polished surface and natural binder, produced in weights from 30g to 150g. It serves:

• Professional calligraphy studios that need a glossy black tone with consistent density — the tone oil soot is chosen for, batch after batch.
• Art supply wholesalers building premium ink lines, who need tone-matched samples before committing to bulk, plus custom label and gift-box branding.
• Export and retail buyers who need archival-grade ink with export-ready documentation and full QC records.

The 30g and 50g formats suit retail shelves and practice sets; the 100g–150g formats serve professional studios and gift programmes. All weights share the same refined soot, glossy tone and batch testing.

Key Features

• Refined oil soot with natural binder — the formulation behind the rich glossy black tone that defines oil soot ink.
• Standardized grinding protocol — controlled soot refining so tone and saturation repeat across batches instead of drifting.
• Batch-level ink density testing — every batch tested for density and color consistency before packaging, with records kept.
• Tone-matching samples before production — a matched sample in 12–15 days from your reference, so bulk production starts only after the color is approved.
• Smooth polished surface finish — presentation-grade sticks for retail and gifting, not rough blanks.
• Custom label and gift box design — brand your programme's packaging; export-ready documentation ships with the order.

How Tone Consistency Is Actually Held

Tone drift is a refining problem, so it is fixed at the refining stage. The facility's standardized grinding protocol controls how the oil soot is refined — because pigment particle quality and uniformity decide saturation, not the hand-crafting that follows. Each batch then passes an ink density test and color consistency check before packaging, so a batch that drifts is caught at the grading station rather than discovered by the studio that receives it. The result is a glossy black that repeats: when a wholesaler reorders, the tone on paper matches the tone they standardized on.

For buyers with an existing tone target, the same system runs in reverse: send your reference, and a tone-matched sample comes back within 12–15 days. Bulk production starts only after you approve that sample — which is why the lead time is quoted from sample approval, and why a buyer ordering 1,500 sticks does so against a color they have already seen.

Reference Case: a Korean Wholesaler, 1,500 Sticks

An art supply wholesaler in Korea ordered 1,500 oil soot Hui ink sticks with custom branded packaging for a premium calligraphy product line. Tone-matched samples were delivered within 12 days and bulk production was completed in 38 days — inside the standard window — with full QC reports. The buyer reported a 98% customer satisfaction rate on the line and placed a repeat order. This case is reported from the order record; your own programme will be confirmed against your tone reference and packaging requirements the same way, starting from the sample stage.

Company Background

Gu Mo Craft Technology operates a vertically integrated ink craft production facility with controlled soot refining, hand-crafting and quality grading stations, serving B2B buyers across more than 30 countries since 2011 with OEM and ODM customization, sample approval workflows and export-ready documentation. The Oil Soot Hui Ink Stick Classic has been featured at the Shanghai International Cultural Products Expo and the Seoul Stationery and Art Materials Fair, where ink tone comparison samples and grinding demonstrations were shown to studio owners and distributors. The stick sits within a Hui ink family that also includes pine soot sticks, colored ink stick sets and student practice formats, so buyers building a full ink assortment can consolidate supply with one supplier.

Before You Place the Order: What to Confirm

Ink sticks are ordered against tone, weight mix and a delivery schedule. Prepare these points before enquiring:

• The weights you need — within the 30g–150g range — and total quantity against the combined 50-piece MOQ.
• Whether you have a tone reference the batch should match (matched samples take 12–15 days).
• Whether custom labels or gift boxes are part of the programme, with artwork requirements.
• Your delivery schedule relative to the 30–45 day production window after sample approval, your preferred trade terms, and destination documentation needs.
