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 ??
| Scarva Replies: | 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 a good base glaze to add oxides to make my own glazes?

asks
Is this glaze food safe? If I add oxides, would it still be food safe?
Thanks
| Scarva Replies: | 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. |

asks
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?
| Scarva Replies: | 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
| Scarva Replies: | 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. |

Emma
from
United Kingdom
asks
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
| Scarva Replies: | 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.

Alycha

United Kingdom
asks
Hi, I’m brand new to pottery and purchased this glaze in power form. I think it would be more cost effective and easier for me to brush on this glaze to begin with. Is the “500ml brush on” pre-made and ready to use or will I still have to mix it with water? If yes, will i need a 100 mesh sieve to do so? Thank you
| Scarva Replies: | Hi, any brush-on glaze is ready to use from the container. Should you wish to turn the powder glaze you have into a brush on glaze you can order our RM1072 Glaze Medium. This will need to be mixed with the powder and passed through a 100 mesh sieve. Hope this helps! |
Alex

I use chrysanthos HF underglazes but cannot get hold of their transparent glaze which fits really well. I have tried another brand but not happy with the finish. Would this be a good fit, firing between 1222-1235°c. Thank you
| Scarva Replies: | Hi there, For this we would actually recommend GZ2136 as it is slightly softer. Hope this helps. |
Anna

Sharon
from
United Kingdom
asks
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.
| Scarva Replies: | 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. |
Helen
from
United Kingdom
asks
Can I put some decoration, using brush on glaze which fires at a lower temperature, with this transparent glaze on top?
| Scarva Replies: | 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. |
