Item#: 16RK105
UPC#: 097539117552
MPN: RK105P
* Copper Penny develops a bright glossy copper finish with various iridescent shades of blue and purple following a proper raku firing.
* Due to the unpredictable nature of this firing technique, results will vary with every firing.
Raku
Mayco Raku glazes are designed to develop beautiful metallic lusters and crackle patterns when fired according to raku firing processes.
Unique Finishes
* From 16th century firing methods in Japan to 20th century reduction methods of the West, Raku firing always reveals exciting and dramatic results.
Gorgeous Iridescent & Metallic Effects
* Glazes designed for the mysterious raku process using combustibles and varying firing methods to produce unique finishes.
* There are several methods and many nuances to raku firing – for our purposes here we define raku firing broadly as the processes of firing an earthenware body and glaze in a kiln, removing the ware from the kiln after it has reached proper temperature, placing it in a container of combustible material and enclosing the container to reduce the oxygen in the container.

** Raku glazes will not produce the same results in a typical electric firing – must encounter a raku environment.
***Due to the unpredictable nature of this firing technique, results will vary with every firing.
General Use
* Shake for 5-6 seconds before use. Stir well.
* Apply 2-3 coats to bisqueware, 2 coats for RK106 and RK107.
** Use of a thermal shock-resistant raku clay body will help reduce the incidence of cracking.
** Do not glaze inside or bottom of the ware.
* Thinner coats tend to produce greater metallic effects. You can adjust your glaze application if you are not getting the desired metallic results.
* Allow to dry thoroughly.
* Fire to cone 06 (1850°F, 1010°C) and hold for 5 minutes. Remove ware from kiln with tongs.
* If using an electric kiln make sure the power is off, and allow to cool.
* Minimizing the distance between the kiln and the reduction container can improve the development of metallic colors.
* Place ware into metal lidded container with combustible materials. Place lid on immediately to reduce oxygen. The combustible materials will produce flames and smoke. Leave in the container until cool, approximately 20 minutes and remove.
* After ware has completely cooled use water and a scouring pad to clean; cleaning will improve the luster and colors in the fired finish.
* Actual fired results will vary according to choice of clay.
* Fundamentals™ Underglazes can be used to put a background color down before burnishing and applying horsehair or feathers in a raku firing.
Safety
- Proper safety processes and personal protective equipment are very important when doing Raku as you are exposed to high heat, flames and smoke.
- Always wear fire protective clothing, fireproof gloves and protective eyewear.
- Do not open or insert tongs into an electric kiln without shutting off.
- Reduction process should take place outside of building due to flames and smoke.
- Do not spray apply glazes without a NIOSH approved respirator and other personal protective equipment.
- Non-Toxic and Non-Hazardous when used according to manufacturer’s directions. Not recommended for food surfaces.
