Can you use them for making coffee?

Does anyone use paper coffee filters to filter shellac after mixing? Bob |

I use drip coffee filters but there has to be a quicker way, so I am interested in what others do also. Fred |

Yep. It's messy and slow. Use a wide-mouth jar and have a number of filters handy. They clog up pretty quickly. I do this procedure outdoors. Surely there's a better way. Cheese cloth? |

I use 3 layers of cheescloth. Or one layer of an old cotton t-shirt. Mike |

We used one of these in the Brune French Polishing class a couple years ago. I got one and it seems to work fine, but I've only mixed up shellac a handful of times. http://www.amazon.com/Wine-Decanting-Fu ... B00069KQJ0 |

I haven't tried it yet but I read somewhere to wrap the flakes in tee-shirt material before inserting into alcohol. Seems like all the filtering would be done for you when you pull out the tee-shirt. I'm going to try it next time. |

Save your coffee filters for the coffee pot. Go to the nearest auto paint distributor (for me that's NAPA) and get yourself some paper auto paint filters. Very cheap. |

Paper paint filters for me too. I think I got mine at a pro paint store. |

You can use de-waxed shellac, but I'm convinced the raw stuff is better. You can de-wax it in two stages: make a "tea bag" of t-shirt material and tie it up, suspend it in a wide mouth jar of alcohol for a day or so, depends on your alcohol and room temp. Pick out the swollen bag and the shellac is mostly wax-free, but let it sit for a day and "decant" it into a clean bottle, leaving the remainders in the original jar. Mostly I just throw my Kusmi seeds into a square shouldered glass bottle of alcohol, and decant off the clear stuff. It sometimes takes several decantings to get super clean stuff, but I like playing with the shellac. |

I use coffee filter paper (clipped to a disposable cup.) Got mine @ $.06 a piece. Then I put a small can upside down on it during filtering. It usually takes overnight or more. |

What is the purpose of filtering it? Just to clean out any type of sediment? or is there another reason? |

| Post subject: | Re: What do you use to filter shellac |
I have not filtered mine at all. I've been using the flakes from LMII, and have seen no sediment or other impurities in it. However, if you are using raw shellacs, they require filtering, to remove wax and impurities like bug parts, etc. |

Same here, never felt the need to filter it even with the darkest variety, however I always used dewaxed. I will soon switch to button and that will need filtering. I read too about dissolving it in a cloth bag suspended in the alcohol. |

I believe Al Carruth uses that method. |

I line a funnel with 3 layers of cotton tee shirt. The LMI Super Blonde has a wee bit of sediment; this method seems to clear it up. |

I just use a paper towel. One sheet will fit into the jar mouth and it filters fast and easy. |

Cheesecloth or paper paint filters with that cheesclothy stuff at the bottom. I start with dewaxed flake. Will a coffee filter remove all the wax from the not-dewaxed stuff? |

I tried coffee filters with a batch of button lac, it was very hard to remove all the wax. I ran it through clean filters 3 times, but there was still some residue. So I let the wax settle out and stuck it in the fridge for a while, it congeals wax and makes it easier to decant the clean shellac. |

You guys should really check out Vijay Velji in San Diego. I've been getting everything from him for 4 years. Super clean, super fresh, high quality and great prices. I've never had to filter other than through a disposable paint strainer to catch undisolved pieces because I was in a hurry. http://shellacfinishes.com/ Great article in Nov/Dec 2010 Finewoodworking about him and his family's Shellac business in India and the process of getting it from a bug to you. You have to have FWW.com access to download the whole article but here is an abstract: http://www.finewoodworking.com/Materials/MaterialsPDF.aspx?id=33678 |

I'm in the LMI flake (#2) non-filtering mode as well. In mixing a new batch I make a saturated soluton with undissolved residue at the bottom of the container. I then decant off the top for use. When I get toward the bottom I'll usually add a bit of alcohl to further dissolve the bottm material and let it sit a while before using. |

David, that's what I do too. Probably got that from you workshop at ASIA last summer. Walter |
