"MDDCL" Firing Schedule

Medalta Decal Firing

Instructions for application:
-Trim around decal.
-Place in shallow pan of warm water, let it curl up. After about 30 seconds it should begin to uncurl, loosen and slide off the paper.
-Position the decal face up and slide it off onto the fired ware surface.
-Sponge from the center until all the excess water, wringles and air bubbles have been removed.
-Let dry for 12-24 hours before firing.

Step	°C	°F	Hold	Time
1	111°C/hr to 43C	200°F/hr to 110F	30min	0:40
2	111°C/hr to 97C	200°F/hr to 208F	45min	1:54
3	194°C/hr to 482C	350°F/hr to 900F		3:53
4	388°C/hr to 821C	700°F/hr to 1510F	20min	5:05

Start temperature assumed: 25°C or 75°F
"Fahrenheit degrees" is not the same as "degrees Fahrenheit". A 100° reading on a Fahrenheit thermometer is equal to a 37° reading on a Celcius thermometer. But "100 Fahrenheit degrees of temperature change" is equivalent "55 Celsius degrees of change". That is an important distinction to understand the above temperature conversions.
