Statistically, the ANOVA (post hoc- Tukey) test was used for hardness testing analysis at a significant P-value of (P&le;0.05). The results show that the amber glass behaviour and composition elements seem similar to VITA ceramics. The addition of amber glass powder to ceramic shows an increase in the HV hardness of specimens. </span></span></span></span><span lang="EN-GB" style="font-size:11.0pt"><span style="line-height:95%"><span linotype="" palatino="" style="font-family:"><span style="color:black">Overall, it was concluded that the </span></span></span></span><span style="font-size:11.0pt"><span style="line-height:95%"><span linotype="" palatino="" style="font-family:"><span style="color:black">amber glass powder could be a promising material for ceramics to use as an additive powder.</span></span></span></span></i> Amber,Ceramic,Hardness,Zirconia,Powder 58 65 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5575-2&slc_lang=en&sid=1 Zainab Dhyaa Fawzy ecc0059@mtu.edu.iq 1800319475328460020400 1800319475328460020400 No Department of Dental Techniques, College of Health and Medical Techniques, Middle Technical University, Iraq Saja Ali Muhsin dr.sajaalshimmary@mtu.edu.iq 1800319475328460020401 1800319475328460020401 Yes Department of Dental Techniques, College of Health and Medical Techniques, Middle Technical University, Iraq Taha Hassan Abood dr.taha1967@mtu.edu.iq 1800319475328460020402 1800319475328460020402 No Department of Materials Techniques Engineering, College of Technical Engineering, Middle Technical University, Iraq
