Physical Properties of Enamel &amp; How Damage Occurs<\/h2>\n<p>Understanding enamel&#8217;s properties helps you protect it better:<\/p>\n<ul>\n<li><strong>Hardness:<\/strong> Mohs hardness of approximately 5-6 (glass is ~5.5, copper is ~2.5-3). Harder than metal, but <strong>brittle<\/strong>.<\/li>\n<li><strong>Toughness:<\/strong> Nearly zero. When struck, it will crack or chip rather than deform.<\/li>\n<li><strong>Compressive Strength:<\/strong> Relatively high \u2014 resists damage under even pressure.<\/li>\n<li><strong>Tensile\/Flexural Strength:<\/strong> Very low \u2014 prone to cracking when bent or subjected to localized pressure.<\/li>\n<li><strong>Thermal Stability:<\/strong> Withstands high temperatures, but <strong>sudden temperature changes<\/strong> (e.g., from extreme cold to sudden heat) may cause cracking.<\/li>\n<li><strong>Chemical Stability:<\/strong> Resists acids, alkalis, and oxidation. However, prolonged exposure to strong acids or alkalis may still corrode the surface.<\/li>\n<\/ul>\n<h2>2.

Frequently Asked Questions (FAQ)<\/h2>\n<h3>Q1: Will high-fired enamel fade over time?<\/h3>\n<p>A: No. High-fired enamel uses mineral pigments permanently fused at high temperatures. Colors will not fade from sun exposure, age, or normal wear.<\/p>\n<h3>Q2: Can scratches on enamel be repaired?<\/h3>\n<p>A: Fine scratches cannot be removed but do not affect overall appearance. Enamel repair requires re-firing, which cannot be done by ordinary repair shops.<\/p>\n<h3>Q3: Can I wear enamel jewelry while washing my hands?<\/h3>\n<p>A: Occasional splashing is fine, but not recommended. Soap chemicals may affect enamel luster, and moisture trapped in metal crevices may cause oxidation. Remove before handwashing.<\/p>\n<h3>Q4: What if the enamel surface looks dull?<\/h3>\n<p>A: This is usually due to oil buildup. Gently wipe with a soft cloth to restore luster. If ineffective, the surface may have been corroded by chemicals.<\/p>\n<h3>Q5: Is chipped or cracked enamel covered by warranty?<\/h3>\n<p>A: Physical damage like chips and cracks is generally not covered by warranty. Please contact us \u2014 we may offer paid repair or replacement services.<\/p>\n<h3>Q6: How can I tell high-fired enamel from resin imitations?<\/h3>\n<p>A: High-fired enamel feels cool to the touch, produces a clear sound when lightly tapped, and has a hard surface. Resin feels warm, is softer, and may show marks when pressed firmly with a fingernail.<\/p>\n<h2>10.
