Kiln Guide

Tempering converts brittle as-quenched martensite into tough, usable steel — but only if you do it right. Learn why two separate cycles beat one long one, how temper temperature controls final hardness, and why a dedicated temper oven beats a kitchen oven every time.

Normalizing relieves internal stress and refines grain structure before hardening. Learn when it matters most, how many cycles to run, and the difference between normalizing and a full anneal — and how to run it in your HotShot oven.

Canola oil, Parks 50, or aluminum plates — the right quench medium depends entirely on your steel. This guide compares all three, explains when to use each, and covers quench technique that prevents warping and cracking.

Carbon steels harden with a simple oil quench. Stainless demands higher temps, longer soaks, and plate quenching. This breakdown covers the key heat treat differences between the two — and what your oven needs to handle both.

1084 and 1095 are the two most popular beginner knife steels. Here’s how their heat treat differs, which quench oil to use, and why 1084 is the better starting point for most new bladesmiths.

Everything you need to set up a home heat treating station: power requirements, quench tank setup, safety gear, ventilation, and which HotShot oven fits your shop and steel lineup.

Outsourcing heat treat costs you time, money, and control. Learn why bringing knife heat treating in-house with a dedicated oven pays off fast — and how to choose the right one for your blade length and steel.
