How to choose, specify and import glass marbles — written for buyers, not for search engines.
Glass is inert in water, but dyed and coated marbles are not. What to test on a sample, which diameter suits which tank, and how to buy aquarium-grade marbles in bulk.
How many marbles a Chinese checkers or solitaire set actually needs, why colour sorting drives your unit cost, and which retail packing formats work for game sets.
Why aerosol cans use a glass marble as a mixing ball, how to match the diameter to the can, and what the glass has to be for a filling line.
The four inputs that set your glass marble unit price, why packing moves freight more than the marble does, and the checks to agree before you release a balance payment.
When an opaque porcelain-style or speckled sesame glass marble outperforms clear glass, which diameters suit decor and aquarium channels, and how to specify the finish.
How 2, 3, 4 and 8-petal cat's eye glass marbles differ, which diameters suit which products, and how to control pattern consistency before a bulk order.
