Tuition and Classes in the Fine Art of Throwing
Glazing is the process of applying a vitreous coat to decorate, harden. and waterproof the finished piece.
Glaze is applied as an emulsion and needs to be fired at high temperatures for the silica (glass) and mineral particles to melt, fuse and crystalise.
Choose your own colours and designs and I will help you achieve the results you want.
Decorating the finished piece is always an individual and personal choice. There are a wide range of different approaches and techniques that can be applied using different coloured glazes, slips and stains.
You decide on what you want, I will be happy to try out different ideas and do sample tests for you.
I keep a small selection of dip glazes in buckets and have a wide selection of different coloured brush on glazes, stains, and raw materials.
If you have something specific in mind, or find some examples online, then let me know and I will do my best to provide the right materials.
Have a look at Youtube where you will find plenty of different ideas.
Here are just a few suggestions for different techniques:
1. When the clay is leather hard (just after turning)
The surface can be painted with wet coloured clay (known as slip) using trailing or brushes.
The surface can also be carved or scratched to make patterns in the surface of the clay.
(Please note that the above techniques cannot be done once a piece has been fired)
2. After bisque firing
The surface can be painted with watered down stains and then finished with a transparent glaze.
Different coloured stains can be painted on top of a white or transparent glaze.
Different coloured glazes can be applied to different parts of the bowl or in stripes or patterns.
Glazes an be applied in layers using reactive or running glazes to get chaotic patterns.
Once you have decorated and glazed your bowls I will fire them a few days later, outside of lesson times. Then they will be ready for you to collect and take away.
Please be aware that I charge £5 per kilo (weight of finished product) on the pieces you take away. That equates to about £2 or £ 3 for each bowl. This helps me cover the cost of materials and electricity.
Please note that I do not allow students to use the kiln themselves.
A kiln is a potentially dangerous piece of equipment. It uses a lot of electricity and gets extremely hot inside. The outside is still quite hot and the areas around a kiln must be kept absolutely clear of combustible materials. It is also not advisable to spend too much time in the close vicinity of a kiln when at high temperature.
A firing will take 24 hours or more to complete. Most of this is cooling down time
Please note that when looking up glazes online you will often see 'cone' numbers instead of temperatures. Cones 1 to 10 are for stoneware, and 01 to 016 are for earthenware. For stoneware bowls I recommend cone 5 or above. These are usually called high fire.
