I have been using Amaco Velvet Underglaze on Bisque ware to decorate it and then dipping into a clear stoneware glaze to great affects (when high fire glaze firing). Will your Multi-Purpose Stoneware Transparent work for this treatment also?

Réponses de Scarva:
|
Yes it should give a similar result, hope this helps.

Really a newbie....having always used a ready made brush on glaze I would like to have a bucket of dipping glaze. So is it just powder to water with no other additives required to make up a bucket. Will this then keep for subsequent dippings if kept with a lid on ??
|
Réponses de Scarva:
|
To make up a powdered glaze simply mix 1000grams of powder with approximately 700-800mls of water, pass through a fine mesh pottery sieve and adjust to a thin cream consistency this is then ready for dipping. It will keep for prolong periods however some glazes when left may settle so make sure to mix well before each use. Hope this helps.

Is this glaze food safe? If I add oxides, would it still be food safe?
Thanks
|
Réponses de Scarva:
|
This glaze is lead free if it is food safe will depend on several factors including the clay body it is applied to, the thickness and the final firing temperature. By adding oxides you are in effect creating a new glaze so will need to be tested separately to confirm it is food safe. Food safety test are carried out by reputable firms like Lucideon.

I've been using this glaze as a base for stains to create colored glazes for a while now and I love it. The finish is very glossy and I sometime would like to tone it down a little...would you be able to suggest any additive that would help the finish become more satin?
|
Réponses de Scarva:
|
It is tricky trying to matting a glossy glaze like this but adding in around 10% china clay will have an effect, you could also lower the final firing temperature as well.

I am using terracotta and decorating slip that fires to 1300c, would I be able to use this glaze to bring out the full colour of the slip, as I cannot find a transparent glaze to fire to 1300c. Many thanks
|
Réponses de Scarva:
|
Yes this is possible however terracotta does not usually fire as high as 1300oC I would double check the firing range before firing just in case.

Which brush on transparent glaze is best for applying on top of spectrum underglazes (on bisque). I'm looking for a clear glaze that will cause the least running/smudging of the underglaze.
Thank you

This glaze is perfect and will work well.

Hi, just bought some.How many dips should I do as a dipping glaze and how many layers as a brush on? Id like to try firing lower than 1250 as my underglazes always looks a bit overcooked.However Id like to avoid cloudy clear glaze.
Many Thanks, Emma

Réponses de Scarva:

Hi,
With transparent glazes thinner is better. For dipping one dip of a suitably hydrated glaze is enough, for brush on 1-2 coats will work best.
Hope this helps!

Hi I bought this as a brush on glaze, and it’s very good, but mine has started to get a bit ‘thick’ as I move down through the bottle. What can I use to thin it please? I wasn’t sure about just adding water? Thank you.

Yes you can thin with a little water, hope this helps.

I have bought this glaze but I need a little help. Can you tell me what proportion of water to glaze powder I should use for a brush on glaze texture and if I need any other additives? Also, can you tell me the proportion of water to powder for your batt wash too? Thanks.
|
Réponses de Scarva:

To make a brush-on glaze mix 1000grams of glaze powder to 700mls of RM1072 Glaze Brush-on medium. Then pass through a sieve this will make a thick glaze which is only suitable for brushing on and not for dipping.
When mixing a glaze for dipping mix 1000grams of glaze powder to 700mls of water, then pass trough a sieve. This will make a glaze suitable for dipping only and not for brushing the reason why is because the glaze brush on medium slows the glaze drying giving an even coat and leaves no brush strokes where as a dipping glaze would dry to fast leaving an uneven and bumpy surface. Each of these recipes may need a little adjustment depending on the glaze used but as a rule of thumb for a dipping glaze you are after the consistency of single cream.
Batt wash is around 500-600mls of water to 1000grams of powder but does not need to be passed through a sieve. The best method to apply batt wash is in thin layers applied in opposite directions, leaving to dry in between coats this may be very slow drying as the kiln shelf is non-porous so you want to plan to do it over a few days.

Can I put some decoration, using brush on glaze which fires at a lower temperature, with this transparent glaze on top?
|
Réponses de Scarva:
|
You can however it is difficult to know what the result will be. The low temperature glaze will melt alot at the higher temperature so it may bubble or graze badly. I would advise testing before on a tile or ideally in the inside of a bowl this way if the glaze does run badly it will not ruin your kiln shelves.
