The shelf, and the size it is not
On this page11
What is here
1,439 rows: 793 containers and 646 closures. 5 mL to 9,464 mL with a median of 118. 430 PET, 133 HDPE, 133 glass, 87 PP and 9 steel.
By format
487 bottles, 281 jars, 13 tubs and pails, 9 tins and 2 tubes. The jars carry brush soap, pigment and basing material; the bottles carry the paint and the washes.
Against the size the craft uses
41 containers at 15 mL or under, 115 at 30 mL or under, 228 at 60 or under and 411 at 120 or under. So the dropper end of this shelf is 115 of 793.
Which is a pipeline fact, not a sourcing one
The archetype behind this group starts at 100 mL because it was written for industrial chemicals. The shelf is the window, and the window is wrong for the work rather than the supply being short.
Say it rather than sell around it
115 containers is a real shelf for a paint decanter and it is not the 793 the count at the top of the page implies. Both numbers are true and only one of them is useful.
The families that matter at the small end
Boston rounds, in PET at 77 and in glass at 71, are the shape this craft recognizes, and the glass ones are the ones a solvent can live in.
And the jars at the wide end
132 PET single wall jars, 33 PP single wall jars and 24 glass straight sided jars. For pigment and brush soap the straight sided glass jar is the better object and the smallest set.
PET is the majority and often the wrong answer
430 of 793. For a water-based acrylic it is fine. For a lacquer, an enamel, a solvent thinner or a decanted primer it is not, and that removes most of the shelf for those products.
Which leaves glass as the serious option
133 containers, 71 of them Boston rounds. Chemically inert, tolerates agitation, shows the pigment load, and is the reason the trade has used it for a century.
How to shop it
Carrier first, which eliminates a resin. Then size, which is the narrow part of this shelf. Then the closure and its liner, which is where the product actually fails.
