|Long Description||Like clay, all glaze materials come from the earth. Traditionally, stones, plants, and other natural materials provided the elements for ceramic surface decoration. In an age of synthetic and mass-produced glazes, handmade glazes from locally sourced ingredients allow artists to produce unique pieces that reflect their surrounding landscapes. In Natural Glazes , Miranda Forrest guides readers through the process of experimentation and discovery to make amazing hues from organic materials. Whether a glaze is mixed from scratch or local items are added to a commercial glaze, this concise book teaches the essential steps. A variety of glaze materials is available in any location, and Forrest shows artists how to recognize and gather appropriate ingredients and prepare them for blending. She explains how to work with vegetation and organic materials such as grass, wood, and seashells, giving step-by-step directions for mixing glazes and testing sample blends for optimal results. Natural Glazes covers application and firing techniques such as raku and offers health and environmental safety information. Natural Glazes contains full-color photographs of completed works, charts and tables providing firing times and other data, and insightful essays from other ceramic artists specializing in natural glaze work. Using found materials in glazes is a creative way to add a local touch to ceramics. With Natural Glazes , inspiration may be as close as your own backyard.|

ISBN stands for International Standard Book Number. Originally this was a 10 digit number known as ISBN-10, but has been replaced with a 13 digit version known as ISBN-13 (aka EAN-13) to better fit in with the industry standard product numbering system.
The ISBN system offers a unique numbering system for books and publications of various types. ISBN offers 9 identification digits for each book or publication and one check digit. ISBN-13 expands the available number set by doubling the available numbers. You might think that the extra three digits would more than double the available numbers but ISBN is limited within the EAN-13 numbering system and will always start with 978 or 979 as the first three digits, leaving only 9 more digits for the actual identification digits and again the last digit is the check digit.
Any ISBN-10 number can be converted to ISBN-13. Any ISBN-13 number that starts with 978 can be converted back to ISBN-10. ISBN-13 numbers that start with 979 cannot be converted to ISBN-10.
The conversion process from ISBN-10 to ISBN-13 is a rather simple one. Start with the first 9 digits of the ISBN-10 number, place 978 in front and calculate the new check digit using the standard EAN check digit calculation.
If you want to calculate the check digit for ISBN-10, that is done using a MOD-11 calculation that is very different than the EAN check digit process.
- Lets start with ISBN-10 number 1-5905-9332-?
- Each digit is multiplied by its position for digits 1-9
- 1x1 + 5x2 + 9x3 + 0x4 + 5x5 + 9x6 + 3x7 + 3x8 + 2x9 = 180
- Now get the remainder 180 mod 11 = 4
- Now return the mod 11 again... 4 mod 11 = 4
- If the results is 10, return the letter X otherwise return the digit.
- For our example, the final number is 1-5905-9332-4
Look at the number above and below the barcode. You will see that except for the last digit in the ISBN number, all of the digits exist in the 13 digit version shown under the barcode right after the 978 and just before the new check digit of 5.
Now you can see how easy it is to convert between ISBN-10 and ISBN-13.
