- Q:I want to get a ! curling iron.Which one is best? titanium, ceramic, or tourmalineShould I get Hot Tools or Baylis or is there a better brand? It will be used at home.Thank youEdie
- In general, ceramic plates are the best for all hair types, but if your hair is frizzy then get a tourmaline ceramic or if your hair is thick and tough to straighten then get a titanium ceramic flat iron. Either one, get a karmin, lol. Those have the most heat settings and features. Plus you get a heat mat and a bag aaaaand a moneyback guarantee if you order it from the right places. Look around online and make sure you get it from a professional hair site so you can get all the guarantees.
- Q:I have the chance to buy a lot of ceramic molds. How do i tell if they are good or damaged from inproper heat use or age?
- Ceramic molds normally mean plaster molds used with clay slip to make hollow thin shelled clay copies that are then fired and glazed. Generally collections of molds that have been used have very little value (I learned years ago) because the erosion that occurs in use distorts the details found on new copies and any physical mishandling chips the edges, resulting in a need to clean-up the molded clay. Also, many molds sold used are out-of-date in that they were made of topics popular for a while but passe now. Normally, if the plaster feels right not soft or discolored, heat or age are not involved. Check the inside surfaces of at least some to see if odd materials were molded that would affect use - I have made wax shells for lost wax casting in my own molds after making slip castings, but don't know what effect it would have on further use with slip.
- Q:I would like to start painting ceramics and was wondering what all i needed to do it? Do i still need to put it in a kiln?
- There are many places where you can purchase ceramic items that are ready to glaze or paint There are shops that will fire the glazed items for you. clay is transformed into ceramic by the firing process. It can simply be allowed to dry, but it will not be as durable.
- Q:plz help
- Most ceramics are insulators, because the bonds are covalent. Electrically conductive ceramics are mostly ionic conductors.
- Q:how do i paint Ceramic tile?
- It depends, ceramic surfaces that get wet need to be painted by professionals otherwise, you will be seeing paint chips within a matter of weeks. This articles explores how to diy painting ceramic tile. Enjoy
- Q:Came across a great pot roast recipe from Cooks Illustrated. but I do not own a dutch oven. Do I need one? And what is a popular size for 2 adults and 1 toddler? I am thinking 6 qt is just too big. What are some recipes that you must use a Dutch Oven for? My pot set has thick bottoms and glass lids, which probably don‘t go in the oven.Also, Ceramic bakeware. Do I need some? I have 3 glass baking 9x13 dishes, and 3 glass pie plates. Wondering why I have no ceramic? What are some recipes that you must use ceramic for? I am thinking glazed ceramic, not porous. But feel free to give opinion on porous bakeware.
- A metal pot and glass lid should work in your oven. Check manufacturer's specs for your item. Dutch oven just means heavy closed pot for slow-cooking. Could probably make the dish in a crock-pot or slow-cooker, as well. You don't need to buy ceramic bake-ware. In 30 years of cooking and raising a family, I never had a ceramic oven dish--except for my crock-pot. Heavy Creuset pots are sooooo expensive. And hard to clean. Here's a story for you. A woman wanted to make a roast for dinner, just like her mother used to make, so she called her for the recipe. Mom said: you take the roast and cut 3 inches off the end, set that aside for something else, and then add your onions, etc She followed her mom's instructions, and the dinner came out great. But she called her mother back and asked her why she had to cut off the end. Her mother said because that's what my mother always did. So they both decided to call Grandma, and ask her why. Grandma's answer was: Because your father and I were so poor when we were first married, I didn't have a pan big enough to hold a roast. Make do. Use it up. Or do without.
- Q:Should I use ceramic tile in a basement appartment?
- Ceramic needs a level floor. Most basement floors are pitched towards a floor drain. Ceramic is also cold and hard on the feet as well as expensive. Consider engineered wood, which is designed for below elevation installation. It will be more stable than laminate. If it's a starver's apartment, use a good basement epoxy paint, throw the chips around that come with, and add some bound carpet ends that you can find fairly cheaply in home improvement centers.
- Q:Which is more expensive, ceramic perm or digital ironing? Which one is better?
- I suggest you do SPA ceramic perm, this hair do not only do not hurt the hair, but also to supplement the nutrition of the hair, have been popular for some time, suggest going to the regular barber shop to do it, you can go online to check the information!
- Q:Because i‘m having brace this sembreakthank you very much. .),tc to all
- To cut off oxygen that can make the fire continue burning or get large !
- Q:I bough a ceramic bowl that says it is safe for dishwasher microwave ,and I want to make a pot pie in it, that needs to go in the oven ad be baked. is this ok?
- Has to be reset. I don't know if you can do that yourself. I have a Snap-on diagnostic scanning tool that does it. I don't know if the $30-$50 ones from Auto Parts stores will do that or not. I don't know if you disconnect the battery if that will work or not. It will temporarily mess up the computer and the security system on your radio. Both of which can be overcome but you must know the radio security code to make it work again. The computer will just have to run a while to reset the driveablility settings.
