The other day one of the teachers, while admiring one of his pieces glazed asked him how he had that beautiful enamel. ─
enamel is a 1280 º C. .. ─ replied. ─
Fiuuuu! and how the oven doing? because mine reaches 1260 º and then I do not think you ever achieve this enamel ...
─ In an oven that suffers a lot ...
Thinking about this and got no pillars of 5 cm high the other day, it had a lot of little things may have to make two batches instead of one, I decided to make supports and pillars for my toaster oven.
Here is the formula for refractories:
kaolin 50% 50%
chamotte medium
Water enough to form a paste that can work.
This mixture is used to make refractory to reach about 1250-1280 ° C. pillars, stalls and stands and even small pieces plates.
Here the steps to make small hand pillars:
With a kilo of kaolin and one chamotte made fourteen pillars, half of 6 cm. height and half of 4 cm high, gruesitos to withstand the weight of the upper plate seamless.
With as much I did (using various cookie cutters to make cookies) different media to support and protect each piece large plates oven.
The cake at 1040 º C and then gave them a bath (in case power is dripping off the piece) with the same I paint the plates. Rafael advised me this recipe, which builds the ovens: Mix paint oven plates:
90% alumina or quartz
8% kaolin
2% bentonite (ie for unsettled both alumina)
Water enough to form a creamy liquid. Paint
three times allowing it to dry between coats for the first time, then every time you jump a bit, with just retouch enough.
