A single reference for the numbers that decide whether a ceramic order ships clean: fired sizes, tolerances, wall thickness, packing density and the test standards US and EU buyers actually ask for. Every figure below is what we quote on our own production lines, and each one is specific enough to put on a purchase order.<\/p>\n

Capacity is measured to the rim minus 10 mm of headroom, which is the fill line a customer actually uses. A mug quoted at 350 ml that overflows at 300 ml was measured to the brim.<\/p>\n

Clay shrinks 10\u201313 percent between forming and glaze firing, so a 30 cm jigger mould lands at 264\u2013270 mm. Always specify the fired number.<\/p>\n

On a 40 foot high cube at 68 m\u00b3 usable, 0.048 m\u00b3 per master means about 1,410 masters. A 2 cm change in carton dimension moves that by 4 to 6 percent.<\/p>\n

A test report should name the article, the glaze and the lab’s accreditation. A report that says “ceramic ware” without an article reference will be rejected by most retail buyers.<\/p>\n

Sampling: the three stages<\/h2>\n

First, a white body sample to confirm geometry and weight. Second, a glazed sample to confirm colour under your own lighting, not the factory’s. Third, a production sample pulled after the first 200 pieces of the run, which is the only stage that catches shrinkage drift and glaze batch variation.<\/p>\n

Keep one piece from each stage and photograph it next to a ruler. A photo without scale cannot settle a claim six months later.<\/p>\n

How to use this reference in practice<\/h2>\n

Numbers on a page only help if they reach the purchase order. The practical workflow is to copy the relevant table into the PO, delete what does not apply, and add the two items that are specific to your order: the glaze code and the artwork file reference.<\/p>\n

A complete PO for a mug order therefore carries six lines: fired capacity and diameter with tolerance, body weight with tolerance, glaze code plus a retained fired chip, decoration method and position, packing specification with carton cubage and gross weight, and the test standard required for the destination market.<\/p>\n

For a plate order, replace the decoration line with well depth and flatness, and add the charger pairing if the range includes one. For a bowl, capacity at the stated depth replaces weight as the critical line, because two bowls with the same diameter can differ by 120 ml.<\/p>\n

Keep the reference updated as specifications change. A number that was correct two years ago is worse than no number, because it gets copied into an order that the factory then builds to.<\/p>\n

Two habits keep the reference useful: date every revision and note which factory line it came from. A tolerance that holds on one kiln does not automatically hold on another, and a number without a source is a number that gets argued about.<\/p>\n

The five mistakes we see most<\/h2>\n

Quoting inches and tolerating centimetres. Approving a single sample instead of a range. Specifying the box before the fired size is fixed. Ignoring carton cubage until the freight quote arrives. And accepting a test report that names no article.<\/p>\n

For the mug-specific detail behind this reference, see our ceramic mug specifications reference<\/a>. For plate geometry and well areas, the plate sizing standards guide<\/a> goes deeper, and current shapes are listed in the ceramic mug<\/a> and dinnerware<\/a> ranges.<\/p>\n
