Avoid Specially treated surfaces (for instance, Arc opal glass) do not allow colours to adhere properly.

Check your ovens temperature control with a thermometer before oven-drying your creations.

Respect the recommended oven drying temperature and time: if they are reduced, glazing will not occur. If they are increased, colours tend to brown, although hardness improves. For large pieces, oven time should be extended by about 10 minutes.

A slight odour may be noticed during oven-drying. It is totally harmless.

These are general guidelines only. It is recommended that you carry out a few tests before working on your own creations.

you can paint over areas that have already been baked, however the adherence could be reduced.

Porcelaine 150 colours are ready to use, but may be diluted with water if desired. Excessive dilution may reduce colour adherence. Dilution of up to 10% with water is acceptable, however this will reduce colour adherence. In our experience, if the item is for any use other than decoration, it is advisable NOT TO DILUTE.

Ensure your paint brush is clean and dry. It is recommended that a fresh dry brush is used for each colour to avoid dilution.

Colour No43, Ivory is pure white when applied from the jar, however this colour darkens to Ivory when baked. (indicating that baking is done)

Always ensure the article is completely dry before baking. Porcelaine 150 is a water based paint, if it is completely dry before baking any water left in the paint will boil and result in bubbling of the paint. Increase your drying time if you have  added several layers of paint or applied heavy outlining.  Paint that is not fully dry will BLISTER when baked.
