Louis Katz Notes: I am not a safety expert and any information contained in this file about safety should be ignored in favor of advice from experts. All of the materials in all glazes are potentially hazardous. All of these glaze recipes are given without any representation of accuracy or safety. They may work, they may not. They may be safe when fired or they may not. All of the materials used in them have hazards associated with them. You must be have sufficient training in the hazards before you use the the materials. You will have to determine the suitability and safety for your use. Do not assume that a lack of a warning about a material means that it is safe.

This is an old standard. I am still using it but have recalculated it with newer Custer. It is a great decorator. It goes well with tenmokus , kakis, St. Johns Black, and over opacified white glazes.

Hazards

09/2016 Note: This is a new feature. If a recipe material is not listed, that material's data has not yet been added. Some materials only have GHS ratings, while others only have HMIS ratings. Warnings differ between systems and countries. Glazy does not take any responsibility for accuracy of linked SDS information. Contact your ceramics supplier for safety information for your specific materials.
Globally Harmonized System (GHS) Hazardous Materials Identification System (HMIS) SDS Link
Material Pictograms Signal Word Hazard Statements Health Flammability Hazard Protection
Whiting Harmful WARNING Causes eye irritation
Silica HarmfulHealth Hazard DANGER From 200-Mesh SDS:
May cause cancer by inhalation.
Causes damage to lungs through prolonged or repeated exposure by inhalation.
* 0 0 E
Kaolin (Theoretical) HarmfulHealth Hazard DANGER SDS for EPK KAOLIN: EPK Kaolin is a naturally occurring mineral, which may contain amounts of crystalline silica
typically 0.1-1.0%, may cause damage to respiratory system through prolonged or repeated
exposure.
Chrome Oxide WARNING May be harmful if inhaled. May cause
irritation to eyes and respiratory tract. Slightly toxic if ingested.
