powder
Let an agent explain powders as a class of granular material, relay production, properties and handling from food science and powder technology sources, describe food and industrial powders, and distinguish powders from dust, granules, pastes and the cosmetic and gunpowder senses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain powders as a class of granular material, relay production, properties and handling from food science and powder technology sources, describe food and industrial powders, and distinguish powders from dust, granules, pastes and the cosmetic and gunpowder senses.
A dry material made of fine solid particles that flows loosely, produced by grinding, milling, spray drying or precipitation, including food powders such as ground spices like cardamom and thyme, milk and instant pudding mixes, spice-biscuit blends such as speculoos, and experimental products such as alcohol powder, as well as industrial powders such as metal, ceramic and pharmaceutical powders; powders are characterised by particle size, flowability and bulk density.
What it is for: Storing, dosing and processing materials in fine particulate form.
It can be explain the class and properties; relay production and handling; describe kinds; distinguish related materials.
Distinguishing features

Engineered properties
Food and industrial forms
What it looks like
A fine loose dry material.
Physical character
typical particle size: about 1-1000 micrometres
key properties: flowability, bulk density, moisture list
spray drying: common for milk and instant products note
How it is recognised
Fine flowing solid particles
Spice powders, food powders, instant pudding mix, alcohol powder, speculoos spice
Dust is unwanted airborne particles; granules are coarser; pastes are wet; gunpowder and face powder are specific senses

- How should food science and powder technology sources be linked?
- The registry entry has merged aliases naming products and speculoos, a biscuit; should they be split off?
