What temperature should I normally fire the bisque too?

We would advise that bisque firing should go to 1000°C (cone 06) over an eight hour cycle.  This can be varied for special requirements.

How do I prepare a glaze & store it?

If you have bought a glaze in powder form or plan to mix your own glazes you will need to prepare them prior to use. You will need a sieve (80’s for stoneware and 120’s for earthenware), a large brush (lawn brush), two wooden slats, and two plastic containers. Before starting make sure all of your utensils are clean. 1. Partly fill one of the containers with water (a third of the container is reasonable but the exact amount will depend on the amount of glaze you are preparing. Trial and error is the best way of discovering the correct amount). Put the glaze powder into the water and mix. (N.B. Always wear a suitable mask when preparing glaze.) 2. Place the sieve over the second container using the slats as support. It is important to ensure it is stable. Pour the glaze mixture into the sieve until it is half full. Use the lawn brush to push the glaze slowly through the sieve, using a circular movement. Squeegee all of the material left in the first container into the sieve using a rubber kidney. Repeat the brushing process until all the glaze has passed through the sieve. Some material residue may be left in the sieve. If this is found dispose of it with care. 3. The product you now have is referred to as glaze slop and could be used immediately, although we recommend leaving the slop overnight before use. 4. When left the glaze slop will settle out. You will find a slurry of glaze material at the bottom of your container and clear water at the top. At this sta . . Read More

I am told clays can be supplied deaired. If so do I need to prepare the clay before use
