Variation In Thickness
In this section we will show you how the thickness of applied glaze affects the final fired outcome. Each glaze has been made up using Scarva Studio Reactive Glaze Medium at a ratio of 1kg glaze to 840ml Reactive Glaze Medium.
The glaze is applied in coats to bisque ware fired to 1000°C. Each coat is brushed perpendicular to the one previous as to achieve even coverage. Each layer was allowed to dry before applying the next. Once applied to the required thickness the finished pieces were fired to Orton Cone 6 at a final firing ramp of 75°C / hour with a soak of 20 minutes.

*Please note whilst every effort has been made to capture colour accuracy, each device and monitor uses different colour profiles and will render images differently. We cannot emphasise strongly enough how important it is to test glazes before comitting them to work.
Instructions for use
To make a dipping glaze
Make sure to assemble all the necessary materials before you begin to mix your glaze. We recommend mixing all your Studio Reactive glaze at once to ensure that all materials are completely homogenised and the outcome is as intended.
What you will need
- Your glaze
- A bucket or bowl large enough to hold your glaze
- A bucket or bowl to receive the prepared glaze
- A mask or respirator
- A glaze mixer, mixing blade attachment and drill or a sturdy whisk
- A 100-mesh sieve
Instructions
- Be sure to wear your mask or respirator when handling powdered glaze in the raw form and always try to keep dust formation to a minimum.
- Add your glaze to your bucket or bowl and slowly add your water at the ratio of 800ml of water for every kilogram of glaze.
- Mix your glaze and water together until combined. Pass through a 100-mesh sieve into your second bowl or bucket.
- Adjust your glaze to your preference - your water hardness will have a bearing on exactly how much you need to use but you should aim for a consistency similar to single pouring cream.

Firing Instructions
We recommend these glazes be fired at Orton Cone 5/6 for best results. Scarva always recommends the use of pyrometric cones as this is the only reliable way to measure heat work in your kiln.
We fired all samples shown at Orton Cone 6, firing at 150°C/hr to 1000°C and 75°C to the equivalent temperature of Orton Cone 6 on our computerised controller.
