Questions about products

To choose the ideal paste for the job you want to do, you need to take a few very important points into consideration:

1- Oven temperature: If the kiln where you're going to fire your pieces is a low-temperature kiln, it's best to choose earthenware pastes; if your kiln can reach higher temperatures, you can always opt for stoneware or porcelain pastes. You should also take into account the glaze you are going to choose as the temperature of your kiln will influence the final result.
2- Technique: The type of work you're going to do is also an important factor when choosing the most suitable paste. If you're going to be modelling, either on the wheel or by hand, there are pastes such as C40SF and GF60 that are perfect for this.
3- Glaze compatibility: The compatibility and application of the glaze can be a very important technical process when choosing a paste. You should always check that the glaze you choose is suitable for the paste you are going to use. The temperature ranges at which glazes and pastes fire can differ.
We recommend storing your clay in a cool, dark and well-packaged place.
As long as the clay remains wrapped in plastic and stored according to the recommended instructions, it will be ready for use at any time. Some clays contain more organic matter than others and can therefore develop mould or mildew. These problems do not affect the performance of the paste and can be removed from the surface with a damp sponge.
The best option for small amounts of clay is to let the paste dry completely before breaking it into small pieces, after which you should place the broken pieces in a bucket. The paste should then be covered with water and left to soak for 24 hours. After 24 hours, the paste should have absorbed the water and become a liquid paste mixture. After this process the paste is ready to be used again.
As a rule, as long as the glazes are from the same family and have the same firing temperature, there is no problem. In any case, as this is an experiment on the part of the client, we advise you to test it before starting your production process.
The term "Food Safe" cannot be applied to a glaze (as supplied). Only the final piece that has already been fired can be considered "Food Safe". This is something that is beyond our control and that of any supplier, as it depends on a huge variety of factors that are impossible to control. The paste itself, the oven and firing, the oxides added are some of the variables to be considered for a product to be "Food Safe". The glaze itself, the oxides or colourings added, the oven, the way it is baked, are some of the variables to consider for a product to be "food safe". However, the only way to guarantee that you have a piece that is considered "Food Safe" is to use a certified ceramics testing laboratory to certify it.
