The Edward Orton Jr. Ceramic Foundation

The Edward Orton Jr. Ceramic Foundation's Thermal Processing Products are designed to monitor high temperature processes. Products include Pyrometric Cones, TempCHEKs, TempTABs and PTCR rings. Orton products provide independent verification of the thermal process in your kiln or furnace. Orton Engineers are available to assist you. https://www.ortonceramic.com/

If you just received your Orton Dilatometer, you may be wondering the proper procedure for setting up your instrument. This video details how to set-up your dilatometer received directly from our instruments department.

Understand the initial installation of the thermocouple, sample holder, and correctly attaching and balancing the weights.

Orton Dilatometer Initial Set-Up

All about Orton's Pyrometric Cones and the shapes they come in. We offer large, small, and self-supporting traditional upright pyrometric cones for use in industrial and hobby applications. We also offer our Pyrometric Bars for use in our proprietary Kiln-Sitter product, to allow you a precise way of slowing your kiln.

Our cone chart is a visual aid to help you more precisely decide on the ideal cone number and correct heating rate for your kiln.

Orton Pyrometric cones are used in kilns throughout the world to monitor temperatures (heatwork)and confirm the uniformity inside kilns. Pyrometric cones are a useful tool to spot small changes taking place inside the kiln over time and also as an aid to help diagnose and troubleshoot firing problems.

When is a Cone 6 fired to a Cone 6? All Potters want to know! This video answers the question. When does it reach its heatwork temperature equivalent.

When is a cone 6 fired to cone 6?

Self-Supporting Cones are the most accurate and easiest to use witness cones available. They provide the same information as Orton Large Cones. The advantage of Self-Supporting cones is that they are the correct height (1 3/4" exposed above the base) and have an 8-degree bending angle built in. They do not require plaques. Self-Supporting Cones can be set on any flat surface.

Self-Supporting Cones are available for use from 1087F to 3106F (586C to 1708C). Cones are numbered from 022 to 32. Cone 022 is the cone that will deform at the lowest temperature (1087F) and cone 32 is the cone that deforms at the highest temperature 3106F (1708C).

Self Supporting Cones are recommended by glaze and kiln manufacturers to achieve the best results.

Why Use Self Supporting Cones?

So you just bought a Vent Master from Orton; now what? This video shows you what to expect when you open the box and a step-by-step guide to installing your new Vent Master.

The Orton Vent Master venting system is easy to install, prevents fumes from entering the workspace, makes sure there is enough oxygen in the kiln for colors to fully develop, improves the temperature uniformity inside the kiln, and helps increase the life of the heating elements. Orton received the Original patent in 1988 for Downdraft venting of Electric Kilns.

How to Install Your Orton Vent Master

$If you weren’t already aware, the cone numbers span from 022 to 42, 022 being the lowest firing temperature and 42 being the highest firing temperature. Be careful to include the “zero” in front of those cone numbers that have it shown. The zero distinguishes between low fire cones and high fire cones. A cone 06 is not the same as cone 6. In fact, there is a 400-degree temperature difference between them. NUMBER: 022 TO 011 – Cones in this low range are used to fire the overglaze decorations, decals, enamels, lusters and for glass slumping, fusing, and decorating. The temperature equivalent range is approximately 1050 - 1550F (560 to 850C). NUMBER: 010 TO 03 – Cones are made in two series for this temperature range: the regular series (iron-containing cones) and an iron-free series (for use in reducing atmospheres). They can be used in the firing of wall tile, craft and art bodies, structural clay products, and glazes. The temperature equivalent range is approximately 1600-2150F (890 to 1170C). NUMBER: 4 TO 12 – These cones are used in the firing of floor tile, stoneware, refractory materials, porcelain, china, and structural clay products. The temperature equivalent range is approximately 2175-2345F (1180 to 1340C). NUMBER: 13 TO 42 – Cones in the highest temperature range are used for firing industrial products up to 3659F (2015C). I hope this video helped you decide which cone number is right for you!$
