In most crafts the container is chosen last. Here it is chosen first, because the contents attack it.

What this covers

Craft glue, wood glue, sealant, varnish, a mod podge style decoupage medium, and wax finish. Six products that a small maker can produce and sell, and that a woodworker, a crafter or a restorer buys without much brand loyalty and a great deal of attention to whether it works.

The archetype states the problem in one line

"Chemical resistance is the entire decision. Check the resin chart first." That is unusual. For most use cases the container is a presentation choice inside a range of workable options. Here the wrong resin fails, slowly, on a shelf, after the customer has paid.

So the resin chart is the first page, not an appendix

Glass rates highest for chemical resistance at 5 of 5 and runs from -100 to 300F. Polypropylene and HDPE both rate Good at 4 of 5 but stop at 240F and 190F. PET also rates Good and stops at 120F, which is the number that catches people out.

And then the labeling

If what you make is an art material, the formulation goes to a toxicologist for review by regulation, and the label carries a specific conformance statement. That is not a recommendation; it is 16 CFR 1500.14(b)(8).

And possibly a child resistant closure

Several of the solvents that make a finish work are listed in 16 CFR 1700.14(a) at thresholds a real formula can reach: methyl alcohol at 4 percent by weight, turpentine at 10 percent, petroleum distillates at 10 percent where the product is thin enough.

Every leaf here is flagged for it already

All six products carry cr_required in our own process constraints, which is why the derived shelf arrives with 39 child resistant closures on it rather than leaving you to go and find one.

What the shelf looks like because of all this

234 containers, and 143 of them HDPE. That is the shape of a craft where chemical resistance leads: the material that tolerates the most, in the shapes a workshop product is sold in, rather than whatever photographs best.

Who this is not for

Anyone hoping to choose a bottle because it looks right and check the chemistry afterwards. On this shelf that order produces a product that passes every test you run in week one and fails in month four.

Written from 16 CFR 1500.14(b)(8), 1500.121 and 1700.14, and from the catalog as it stood on 17 October 2026. Whether a particular product is an art material, what its chronic hazard labeling should say, and whether its closure must be child resistant are determinations about a specific formula; the first of those is a question for a toxicologist by regulation, and nothing here substitutes for one.
