Development of Red Ceramic Pigments with Perovskite Structure Prepared through a Traditional Route
Round 1
Reviewer 1 Report
The authors undertook the Development of red ceramic pigments with perovskite structure prepared by traditional route.
1.I did not find any novelty of the present work, please include in the introduction.
2. Authors need to discus how this work is combat associated issue at the end of introduction.
3. More SEM images are required.. Like edges.... to confirm the pervoskite structure.

Thank you for your review.
We have rewritten with an english native speaker in order to correct all mistakes.

Reviewer 2 Report
Miguel et al reported the study in obtaining solid solutions of ceramic pigments of red tonality with YAlO3 perovskite structure doped with chromium by means of conventional synthesis "Ceramic Route". The pigments obtained have been characterized by X-Ray Diffraction to identify the crystalline phases responsible for the color, highlighting the formation of the perovskite crystalline structure YAlO3 responsible for the red coloration, together with lateral phases of garnet Y3Al5O12 of lower intensity. Ultraviolet-visible spectrophotometry shows absorption bands corresponding to Cr(III) in octahedral position and appearance of Cr(IV) in both octahedral and tetrahedral positions. The morphology of the samples has been studied using a scanning electron microscope, obtaining information from the secondary and backscattered electrons. The work was carefully carried out and the results are nice and significant. It will provide valuable addition to the design of novel ceramic pigments. I recommend publication of this work in Eng after some revisions:
1. The quality of the figures presented in the manuscript can be improved.
2. The scale bar should be provided for the SEM micrography of pigment in Figs 12 and 13.
3. English language and style are fine, but minor spell check will be required.
4. In the introduction part, please provide more sufficient background and include more relevant references in the manuscript.
5. Based on the structural characterization, the structural illustration of the prepared ceramic pigments should be provided in the manuscript.
6. Some important review articles on other transition-metal or rare-earth-metal based pigments should be added for more balanced reference citation: (e.g., Chem. Rev. 2015, 115, 7589; Acc. Mater. Res. 2022, 3, 830; Light: Science & Applications 2022, 11, 177; Adv. Opt. Mater. 2020, 8, 2000985, etc.).

Dear reviewer,
First of all I want to thank you all your comments and suggestions, and I want to apologize for the delay in replying, but I have had some health problems that have prevented me from doing my job normally.

Sorry but those are the maximum quality we can obtain from software

Reviewer 3 Report
The paper draft provide a novel method to form pervoskite color glaze which is interesting. However, lots of language problem existed that reduce its readibility. The figures and data is not well organized as well. Therefore, major revision is needed.
(1) the academic writing of the manuscript need to be improved significantly since there are lots of grammatical error and typo. For example, Page 1, line 35, 41, subject is needed before "that must". Page 11, line 246, a comma is needed after as a pigment. There are other similar problem. Page 13, line 284, delete the blank in Cr(VI ).
(2) In the end of the Introduction, generally aim and scope of the research should be mentioned.
(3)the title 3.1 is unclear, should be crystalline characterization of .... same problem with title 3.2.2
(4) Figure 5, y-axis should start from 0, why is -0.2?
(5) The sem image in Figure 12, 13 is blurry, and hard to see. Besides, redraw the scale bar, remove the label.
(6) Figure 15, all fired at 1300 oC, why figure 15v is 1200C? why not make it consistent?
(7) Figure 18, the figure legend should put inside the figure. Please reorganize it.

(4) Figure 5, y-axis should start from 0, why is -0.2?
All figures related with UV-Vis are in this scale, because the software they have can not change the scalebar. All data are given as jpg image, and we don't have the data to replot. The only way to change is to repeat them, but they don't have availability until the end of January. Sorry

(6) Figure 15, all fired at 1300 oC, why figure 15v is 1200C? why not make it consistent?
Sorry it was a mistake. Really it was fired at 1300ºC. I have changed this value
(7) Figure 18, the figure legend should put inside the figure. Please reorganize it.
Done
