Ceramic paste is the already prepared material with which we are going to produce our ceramic pieces. (Manual Pratico de Introdução à Cerâmica, Arlindo Fagundes).
Ceramics is the craft that transforms the raw material (i.e. ceramic paste) into objects that are subjected to higher temperatures. These ceramic pastes must be fired in special ceramic kilns (muflas), which reach these temperatures. Each paste can have different firing temperature indications and are usually divided into two categories, low and high. high temperature (see the instructions for each folder).
These are the low-temperature pastes we prefer to work with, for various reasons inherent to their properties, but also because they are of national origin.

We also have GRÉS ceramic paste (high temperature).

It's important to keep the paste well packaged while it's in storage. Keep the paste packed (you can reinforce it with another plastic bag), tightly closed and without holes, and store it in a cool, humid place.
The ceramic samples - earthenware, terracotta and red clay - shown in the images are considered low-temperature and were fired at 1020°. Product images may vary in tone and color according to monitor settings.
The image of the folders is illustrative, there may be variations in format, color and packaging.

We have an outside cooking service, we do batches and high temperatures to bake your pieces.
