How We Research

Updated on

Kilns, clays and glazes are linked by firing temperatures and safety. PotteryHow follows those links to help hobbyists and studios choose materials and equipment that will work together. Coverage: Kilns, Kiln Parts & Ventilation, Pottery Clay, Glazes & Underglazes, Pottery Tools, Books & Learning.

Our sources

  • Cone ranges and firing schedules provided by clay and glaze manufacturers
  • Kiln electrical requirements, interior volume and element details from manuals
  • Safety data sheets for glazes and underglazes, including food-safe claims
  • Ventilation recommendations from kiln makers and studio safety guidance
  • Studio instructors and ceramics forums about glaze defects and kiln element wear

What we check on pottery & ceramics

  • Firing range: Clay, glaze and kiln must share a cone range, so every guide states it up front.
  • Safety and ventilation: Kiln venting, electrical load and glaze handling are covered as part of buying decisions.
  • Durability and parts: Element and thermocouple replacement cost and availability affect kiln ownership.
  • Value over time: Bulk clay, tool sets and studio classes are compared with ongoing hobby spending.

What a product must show to be listed

Products with unclear firing ranges or missing safety documents are cut. The shortlist is divided into beginners, home studios and small production potters.

What we do not do

We are not a testing lab for glaze safety, so food-safe statements are relayed from makers and flagged for verification.

AI and editing

Drafting is partly assisted by AI software. Nothing is published until it has been compared with the manuals, listings and references named on this page, and mistakes are corrected as soon as they are reported.

Affiliate disclosure

Some links on PotteryHow are affiliate links, so we may be paid if you buy. That income does not influence selection or ranking. See the Affiliate Disclaimer for details.

Keeping pages current

Kiln pages are revisited yearly, while clay and glaze lists are checked every six months. Prices, stock and models shift, so we replace discontinued items and change the date at the top when a page is edited. If you spot an error, contact us and we will look into it.
