I would recommend firing this product at 80ºC per hour to 300ºC then 120ºC to 1235ºC with a 30 minute soak on a computerized controller. If you are still struggling to achieve a good result please email we pictures and I will give some hints on how to resolve.

I would recommend using approximately 700-800mls of water to 1000grams of powdered glaze.

Can you water down brush on Terracolor 620 Lugano Blue to use as pouring glaze for something like the inside of a small jug where brushing would be impossible. The outside would be brushed with the undiluted glaze in this instance.

Not really, still going to be to thick.

Hi, what is the specific gravity for lugano blue?
Cheers.

Hi, we find that starting with adding 900ml of water to 1000g of glaze and adjusting as necessary to achieve the consistency of thin pouring cream is more effective than measuring specific gravity, as it is dependent on your water hardness. Hope this helps.

If a glaze is food safe our not depends on several factors including the type of clay used, the firing temperature, the shape of the vessel, the thickness of glaze even the position of the vessel in the kiln can have an effect on the glaze. Ideally a food safe test would be carried out by a reputable body like British Ceram. The 620 Lugano Blue Glaze would most likely pass a food safe test providing it was fired on a suitable body like our ES5 Earthstone Original in an electric kiln and to the suggested temperatures.

Terracolor Powder Stoneware Glazes are a more cost effective and faster approach to glazing a larger volume of pots. Simply mix the powder with water and pass through a sieve to create a dipping glaze. All Terracolor glazes are Lead Free.
