Hydrometer (6 inch)
Using a hydrometer to check the thickness of your slip or glaze each time before you use it will help you create more consistent results. I've included a hydrometer number on my slips and glazes as a reference for you when you use my products.
Mixing Instructions Using a Hydrometer: This 6" hydrometer is small enough to use in 5 gallon (or smaller) amounts of slips and glazes. Once you've added water to your slip or glaze, and screened it twice, you'll want to get a reading on how much water to particle material you have. If it's too thick (the number on the hydrometer is higher) you'll want to add more water, stir, and check it again. Once you have gotten the hydrometer reading where you want it - mark it into your notes (or on the bucket) so you'll have it as a reference when you go to use it again.
More Instructions on using your Hydrometer:
1) Place the hydrometer into your liquid batch of slip or glaze with the dark, narrow end facing down.
2) You'll notice it will "rest" or stop in the surface of the glaze part way down on the hydrometer. I usually take the hydrometer and lift it up a little - then - I re-drop it into the liquid for a more accurate reading.
3) There is a number scale on one side of the hydrometer that reads from 0 - 70. Most slips and glazes will rest somewhere between 55-40.
Note: Most of my slips and glazes on my site will suggest a hydrometer reading in their description. Email me if I've missed any and I'll be sure to get back to you asap.
