The wood of every wooden baseball bat (Louisville Slugger ran ash for a century before the maple shift in the 1990s; ash is the historical bat wood), every traditional wooden tool handle (axe, hammer, sledge), every Windsor chair leg, every shaker cabinet door panel that wasn't cherry. White ash is a ring-porous deciduous hardwood from the eastern US — the rings show as the visible coarse pore-bands that give ash its distinctive grain reading. The defining mechanical property is its shock-absorbing flex — bat-grade ash bends at impact and recovers without splintering, which is why it ruled the baseball-bat industry until the maple wave. The other defining fact is the emerald ash borer (Agrilus planipennis), an invasive beetle that has killed hundreds of millions of North American ash trees since 2002 — supply is increasingly tight and FSC-certification difficult. Buy from Rockler / Woodcraft / regional hardwood dealers; consider salvaged-ash from felled / borer-killed trees as a sustainable choice.
Fraxinus americana, family Oleaceae. Density 600–680 kg/m³ (12 percent MC). Modulus of rupture 100–115 MPa. Modulus of elasticity 11.5–13.0 GPa. Compression parallel to grain 55–60 MPa. Shrinkage radial 4.9 percent / tangential 7.8 percent. Janka hardness ~5900 N (1320 lbf). Color: heartwood light to medium tan-brown; sapwood nearly white, often appearing as much as 50 percent of the lumber by volume (the 'white' in white ash refers to the sapwood). Ring-porous structure — large vessels in the early-wood band, dense fibers in the late-wood band — gives the open coarse grain readable across a room and the high shock-absorbing flex. Grain straight; texture coarse. Steam-bends well (the Windsor-chair joinery property). Works well — turns, mills, takes finish; raises grain on the early-wood vessels under water-based finishes. Glues and fastens readily. Bat-grade ash is selected from straight-grained pieces with high modulus of elasticity and minimum knots in the strike zone.

The shock-absorbing American hardwood — baseball-bat grade. Mills cleanly with the typical upcut + compression sequence; pronounced grain takes engraving sharply. Good substitute for oak when the customer wants pale stock.

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, with cost-over-volume curves, trade-off profiles, equipment-tier filters, and second-life paths layered onto the data so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
